SURVEY

Activities Regarding the Development and Design ofEnvironmentally Friendly Products
H. SEGAWA

We JTEKT have established six specialized environmental subcommittees under the Global Environmental
Conservation Committee, through which our entire company promotes environmental conservation activities. The
Environmental Responsive Products Subcommittee, which is one of these subcommittees, promotes conservation
within the development and design stages of environmentally friendly products. In 2003, this group laid down a"basic type of environmental efficiency" as the common benchmark for all JTEKT group products, and in 2016
the group changed the base year from the initial 2003 to 2010 when formulating the JTEKT mid-term target plan,
which has stricter targets to be fulfilled. The report introduces the activities within the Environmental Responsive
Products Subcommittee geared towards the fulfillment of the Environmental Action Plan 2020.
Key Words: Development, design, environment, products

1. Introduction
In recent years, there has been a growing interest inplanet environmental issues due to factors such as the
Kyoto Protocol, which was adopted in 1997 at Conferenceof Parties to the UN Framework Convention on Climate
Change (UNFCCC) III (COP3) entering into force in2005 and the establishment of legislation regarding
1)
environmentally hazardous substances . Moreover, at thest
21 Conference of the Parties to the UNFCCC, or COP21,
held in Paris in November 2015 each member country
submitted their CO2 reduction targets to the UNFCCC
secretariat. In Japan, an international commitment to
reduce CO2 by the year 2030 by 26% compared to 2013
levels (25.4% compared to 2005) was submitted, anda long-term target of achieving an approximate 80%
reduction by FY2050 was established. Of this, the 20%of Japan’s CO2 emissions is estimated to be produced by
the transport sector, which includes automobiles. Eachautomotive manufacturer and car parts manufacturer
considers response to environmental issues as a major
issue and engages in initiatives to broadly assess theimpact of corporate activities on the environment, as wellas contribute to the sustainable development of the planetand society. Automotive manufacturers are exerting
maximum effort to improve fuel efficiency of cars as themost effective means of reducing CO2 emissions. Car fuelefficiency is improving more and more each year withthe average fuel efficiency of gasoline-driven passenger
vehicles at 22.4 km/L in 2014, which greatly exceeds the

JTEKT ENGINEERING JOURNAL English Edition No. 1015E (2018)2015 fuel efficiency standard equivalent level (17.4 km/L)
2)
and even the 2020 one (20.7 km/L) .
JTEKT also delivers a high number of products to theautomobile industry and is being required to develop
and design environmentally friendly products to help
further improve vehicle efficiency. As part of this, inMarch 2011 we formulated JTEKT Group Environmental
Vision, which comprises of an Environmental Philosophy
and Environmental Policy which stipulates the content
of initiatives for conserving the planet’s environment.
JTEKT has established an action plan for achieving
targets and is promoting ongoing activities with the aimof realizing a sustainable society.

environmental management3), 4)
As one initiative to achieve our Corporate Philosophyof “Seek to contribute to the happiness of people andthe abundance of society through product manufacturingthat wins the trust of society.”, JTEKT established the
Global Environmental Conservation Committee, which
is chaired by our president, in the 1990s and engages inenvironmental management. The committee promotes
environmental conservation activities by discussing
and determining targets based on company policy andestablishing six specialized subcommittees in order topromote, and monitor the progress of, major themes
raised in our Environmental Policy (Fig. 1).

in JTEKT’s four business areas (steering, driveline,
bearings, machine tools & mechatronics) and offers
several environmentally friendly products to customers
around the globe. Below introduces an example of thetransition of environmentally friendly products offered by
JTEKT.
<Steering>
Of a vehicle’s basic functions, “traveling,” “turning”
and “stopping,” steering products serve the function of“turning.” In 1988, JTEKT developed the world’s firstelectric power steering (EPS) which offers approximately
3% better fuel efficiency than the conventional hydraulicpower steering (HPS) and greatly contributes to reductionof energy consumption. JTEKT’s EPS also boasts
excellent mountability and is our flagship environmentallyfriendly products. From the year 2000 onwards, there
was a rapid increase in the number of EPS adopted, and
JTEKT offers EPS tailored a variety of needs. As a result,in FY2015, EPS accounted for approximately 75% of all
steering product shipments (Fig. 2).

One of these is the “Environmental Responsive
Products Subcommittee”, which is comprised of members
across the development and design departments, andhas promoted initiatives from the development anddesign stages of environmentally friendly products fromthe perspective of reducing environmental burden, inparticular, prevention of global warming.

Bearing products contribute to “movement” in allindustries. JTEKT provides many environmentallyfriendly products leveraging low-friction loss technology
targeting industrial machinery such as wind power
generation and high-speed rail, and the automotive
industry.
In regards to tapered roller bearings (TRB), throughthe control of lubricant amount and optimization ofthinternal design, we have developed the 4 generation
TRB-LFT (LFT: Low Friction Torque), which achieves
a reduction in friction loss as much as 50% compared tond
2 generation TRB-LFT through implementation of low
torque measures. This product was added to the lineup
in October 2015 and is greatly contributing to society
through helping to protect the environment, in particularin terms of lowering fuel consumption and achieving
high-efficiency of vehicles.
Since it was developed in 1980, JTEKT’s TRBLFT has been improved many times and, in FY2015,
accounted for approximately 50% of all TRB shipments(Fig. 4).

JTEKT ENGINEERING JOURNAL English Edition No. 1015E (2018)<Machine Tools & Mechatronics>
In the machine tools & mechatronics business, JTEKT
is supporting the “roots of manufacturing” by offering
grinders, machining centers, cutting machines and soforth. Based on an awareness that reducing energy
consumption and conserving resources to help prevent
global warming are important from the perspective ofprotecting our planet’s environment, JTEKT engages inthe below three items as our main initiatives to promote
the development and design of environmentally friendly
products which incorporate energy-saving technologies
to the maximum extent and such products accounted
for approximately 70% of all those shipped in FY2015(Fig. 5).
[Major initiative items]①Adoption of an eco-mode control (equipment idlestop) in order to reduce standby energy consumption②Adoption of energy-saving devices such as highefficiency variable capacity type vane pumps, etc. inorder to reduce regular energy consumption③Adoption of the fastest CNC and high-speed networkin order to reduce cycle time

status, this product has been adopted by many vehicles.
As efforts to improve fuel efficiency in considerationof the environment have progressed over the years, ademand has emerged for better fuel efficiency in AWD
vehicles also. In order to meet such needs, JTEKT has
made its ITCC increasingly environmentally-friendly
through improvements such as low viscosity of theinternal hydraulic oil and reduced torque through creative
clutch groove design. In FY2015, environmentallyfriendly product (ITCC) accounted for around 86% of all
JTEKT’s ITCC shipments (Fig. 3).

3. 2 Develop new technologies and products to leadthe way in reducing environmental burden
JTEKT has defined its own unique basic formula forenvironmental efficiency in order to make numericalevaluations as an indication of a product’s effectivenessin reducing environmental burden. The higher thevalue derived from this basic formula is, the greater theenvironmental burden reduction and the Environmental
Responsive Products Subcommittee has focused on theenvironmentally friendly products developed each year to
select those which lead the way with respect to the mostimportant themes and engages in product developmentby establishing higher environmental efficiency value
targets and evaluating the level to which this target has
4)been reached . This section introduces the basic formulafor environmental efficiency and some initiatives of theEnvironmental Responsive Products Subcommittee.

3. 2. 1 Environmental efficiency3)
In 2003, the “environmental efficiency basic formula⑴” was established as a common indicator for all JTEKTGroup products. This basic formula divides a product’s
performance (positive impact on the environment) witha product’s environmental burden (negative impact on
the environment) to derive a weight term (W), a loss
term (T) and an energy term (E) as the fundamental
representative traits as it is difficult to accurately ascertain
the environmental burden value for each product. Here,the level of performance improvement for products is
not considered for the time being and, if the product type
differs greatly, conversions are made such as replacingwith other representative traits. Also, an environmental
efficiency value ⑵ and environmental burden reduction
rate ⑶ have been established as straightforward,
quantitative indicators for the environmental efficiency
improvement of environmentally friendly products. Thisis expressed as a ratio of the environmental indicator fora conventional product and the environmental efficiency
of a new product with the same purpose of application,
or a reduction ratio (percentage). At first, “conventional
product” referred to products existing in 2003 prior tothis formula being introduced, however when JTEKT’s
medium-term targets were established in 2016, thereference point for conventional products was revised andbecame based on 2010 products, thus making the criteria
even stricter.
By using this common indicator establishedindependently by JTEKT Group and evaluating theachievements of developing and designing all products
on an even playing field, JTEKT has endeavored to help
protect our planet’s environment.

3. 2. 2 Introducing leading activities
This section introduces an example of a themefocused activity engaged in over the past three years foreach JTEKT business area (steering, driveline, bearings,
machine tools & mechatronics) (Table 2).
<Steering>
JTEKT’s column-assist type electric power steering(C-EPS) is suitable for compact cars with minimalengine room space as its power assist unit is situatedin the vehicle cabin. JTEKT engaged in an activity to
reduce weight by primarily focusing on the composite
components of this power assist unit. By revising theinternal structure and components of the MCU (Motor
Controller Unit) and making the intermediate shaft andcolumn intermediate shaft hollow, we succeeded in
reducing weight without losing rigidity. Compared to theconventional product, weight reduction of 8% and energyconsumption reduction of 83% were achieved, which inturn achieved an environmental burden reduction ratio of21%.
<Driveline>
The ITCC, which controls distribution of front/rear
wheel torque, conveys torque to the rear wheels bycontrolling the main clutch via the control clutch and
JTEKT successfully improved the operating efficiency
during low temperatures by improving the control clutch
groove. We appropriated the maximum load capacitythat driveline components should possess and madecomponents smaller and lighter (13% mass reduction).
The improvement in operating efficiency resulted in atorque loss reduction of 27% and energy loss reduction of
68% in addition to achieving a 32% environmental burden
reduction ratio.

agitating loss reduction, low viscous grease oil, optimized
seal lip design and so on through the deepening oftribology technology focused on each bearing element
as well as the optimization of internal design and flow
control.
This achieved a reduction in torque to as much as
50% depending on bearing specifications and an average
environmental burden reduction ratio of 14%.
<Machine tools & mechatronics>
The PLC (Programmable Logic Controller) serves as
the brains of a machine tool and is required to be of aflexible structure to suit the equipment scale.
For the board-type safety PLC, we have simplified thestructure by abolishing the resin housing and reduced
the amount of materials used as well as concentrated
circuits to reduce microcomputer usage. Furthermore, asa result of reducing power consumption by 1.2kWh/year,
an environmental burden reduction ratio of 39% wasachieved.

3. 3 Promotion of 3R (Reduce, Reuse, Recycle)
design considering effective utilization of
resources
The “3R” activity aims to “reduce,” “reuse” and“recycle” through environmental designs. At JTEKT,
we promote development and design from the concept
phase keeping in mind the following points; “reducing
resource usage through making products smaller, lighterand longer lasting” and “product design enabling easy
recycling.” This section introduces an example of atheme-focused activity engaged in over the past three
years for each JTEKT business area (steering, driveline,
bearings, machine tools & mechatronics) (Table 3).
<Steering>
The EPS is equipped with a torque sensor to detect theamount of steering force needed for the driver to turn avehicle’s steering wheel. We improved the housing forthis torque sensor, which is also attached to the EPS,
by changing from the conventional aluminum die cast
to a resin sensor housing integrated molding. This hasachieved a weight reduction of 33% compared to theconventional product and helped to reduce the amount ofsteel used.
<Driveline>
In regards to vane pumps for CVT (Continuously
Variable Transmission) lubricant, we developed a standalone type vane pump to replace the coaxial inscribedgear pump and achieve size/weight reduction. By making
the diameter of the main unit’s rotating portion smaller(52% reduction) and changing the pump case material
from forged steel to aluminum, we succeeded in reducing

14

weight by 80%. By reducing resource usage and reducing
weight through material changes, we are helping to
improve the fuel efficiency of vehicles.
<Bearings>
Regarding low torque ball bearings supporting highaxial loads, by adopting an oil quantity controlling cageleveraging LFT technology, we have reduced torque loss
compared to conventional deep groove ball bearings.
Furthermore, by increasing raceway depth on the side
subjected to axial load, we have reduced the external
diameter by 10% as well as improved axial load resistance(by 1.8 times compared to the conventional product). Thiseffort is contributing to improved vehicle fuel efficiency
through reduction of torque loss and weight reduction bysize reduction.
<Machine tools & mechatronics>
Conventional safety PLCs used vanadium lithium
secondary batteries for the backup function of internal
memory and the internal clock. JTEKT has eliminatedthe need to use batteries by using a non-volatile memory
for PLC internal data and performing backup with an
IC super capacitor for the clock. This has resulted ineliminating battery waste altogether, thus contributing towaste reduction and reducing the weight of the productthrough removing the need for batteries.

3. 4 Environmental assessments during thedevelopment and design stages
In recent years, amidst growing awareness ofenvironmental issues, car parts manufacturers are also
being required to disseminate products with as little
environmental burden as possible throughout society.
As such, a trend has emerged whereby information
pertaining to environmental burden throughout aproduct’s entire lifecycle (from raw material procurement
to manufacturing, transportation, usage, disposal andrecycle) known as “LCA” or “Life Cycle Assessment” isdisplayed so that consumers can select environmentallyfriendly products. Regarding LCA, ISO standards
have been established amongst international standardsof environmental management published by the ISO(International Organization for Standardization). As such,many Japanese businesses are also incorporating LCA in
their CSR reports, etc.
JTEKT is a member of the LCA subcommittee for
JAPIA (Japan Auto Parts Industries Association), which
comprises of car parts manufacturers, and promotes thedevelopment and design of environmentally friendly
products through examining the concept of calculating
life cycle environmental burden effectively (for the
manufacturing and usage stages) and establishing various
internal institutions to perform checks for the proper

3. 5 Contribution to reducing CO2 emissions byproduct
At JTEKT, a company that promotes the development
and design of environmentally friendly products
contributing to reduction of CO2 emissions, promoting
improvement of products as part of the abovementioned
Environmental Action Plan 2020, we have set the newenvironmental indicators of reducing CO 2 emissions
during product use and contributing to the preventionof global warming through a product’s lifecycle. We
have adopted the “carbon neutral” concept, whereby ouroverall CO2 emissions is offset by the degree to which
we contribute to CO2 reduction, and we have set a goal
for the degree our products contribute to CO2 reduction
to be equal to or greater than JTEKT Group’s overall
4)CO2 emissions by the year 2020. The Environmental
Responsive Products Subcommittee is diligently working
to fast-track the 2020 target to 2019 (Fig. 6).

investigate the establishment of environmental indicators
incorporating this LCA perspective.
In the automotive industry, EV (Electric Vehicles) andFCV (Fuel Cell Vehicles) are expected to increase inpopularity moving forward, and, to respond to this trend,
JTEKT also has an obligation of offering its customers
many No. 1 & Only One products fusing the various
technologies of steering, driveline, bearings and machine
tools & mechatronics.
Moreover, in an effort to achieve our Environmental
Challenge 2050, the Environmental Responsive Products
Subcommittee is conducting technological training for
its engineers and spreading the concept of development/
design with an awareness of CO2 reduction throughout
the entire JTEKT Group in order to further strengthen
our cohesiveness and accelerate activities to send
environmentally friendly products out into the world.

4. Conclusion
This paper has introduced the Environmental
Responsive Products Subcommittee’s initiatives for thedevelopment and design of environmentally friendly
products.
Although not mentioned in this paper, world-wide
environmental restrictions relating to chemical substances
are intensifying every year. Last year, in order to properly
respond to environmental restrictions relating to chemical
substances contained in products, JTEKT establisheda Product Environmental Committee, which has begun
managing chemical substances contained in products.
Section 3. 4 of this paper introduced LCA-related
initiatives. However, with environmental restrictions
intensifying even further in the future, companies will be
under even more pressure to engage in environmentallyorientated initiatives. To meet such a demand, we need to16
