4Innovative Market Solutions

The Global Roller division which includes the sheet metal stamping plant is an integral part of the Tsubaki Nakashima
world wide organisation. The division comprises four roller plants, in the Netherlands, Bosnia, Poland and the USA
and a precision stamping facility also in the Netherlands.

Our industry position as the largest independent manufacturer of precision rollers allows TN the flexibility to offer
products matching a wide range of customer specifications. Our roller technologies have been proven to create lower
friction, bear heavier loads, and withstand the most severe conditions, ensuring that bearings containing TN rollers
have the longest possible service life.
Our products are used in a growing number of applications, including transmissions, engines, pumps, wheel bearings,
mining, heavy industry and railway.

Rollers for Hybrid and Electric Vehicles (EV’s)
The transformation from internal combustion engine vehicles to hybrids and electrics (EV’s) is growing rapidly. Thisevolution presents a challenge for bearing manufacturers, a big challenge to adapt and improve current product offerings to the specific requirements of these radical and exciting new vehicles.
Full electric vehicles, as opposed to hybrids, will havea significantly reduced number of bearings. For EV’s,
which are noiseless vehicles, the technological functionalities of these bearings are expected to improve. Energy
efficient solutions for hybrid and electric vehicles are key,
resulting in reduced friction and lightweight designs. The
technical challenges to optimize the performance of the
bearing must be combined with increased life.
The expectation is that full Electric Vehicles will provide 3
to 5 times more mileage compared to current internal
combustion engine vehicles.

To support our customers with the extended
requirements in bearing design, Tsubaki Nakashima hasdeveloped the Class 1 roller. These rollers (tapered andcylindrical) are the best fit for bearings specially designed
for hybrid- and electrical vehicle applications.

Class 1 rollers have optimized geometry, extremelysmooth superfinished end faces and the spread on all
quality parameters between the rollers in one bearing set
is less than one micron. This is achieved by packing therollers in a tube in the sequence they are produced. This
packing also guarantees that the raceway surfaces of therollers have not been in contact with each other after thelast superfinishing operation. This avoids any microdamages resulting in less noise and longer life. Please referto the table on page 11 for comparison of the TN Roller
Classes.

COMMERCIAL VEHICLES High Performance Solutions For A Growing Market
The safe and economical performance of commercial vehicles relies on high quality, precision components that go
the extra mile. From steering to stopping, commercial vehicles are subject to serious challenges. We understand thedemands of this growing market and produce components that will function safely, efficiently, and consistently for thelong term.

Non Destructive Testing
At a minimum, we guarantee that all rollers pass
extensive (NDT) Non Destructive Testing inspections.
If requested, TN can deliver EN 10204:3.1 certificatesfor each lot (pallet or other packing unit). Traceabilityof process data and quality records is guaranteed for aminimum of 20 years. NDT inspections are structured
and managed according to the requirements of ISO
9712:2012. Strict authorisation levels are applied before
release of batches.

The Heat Treatment process is compliant with CQI-9
requirements, defined by AIAG (Automotive Industry
Action Group). 100% eddy-current surface inspectionof raw material (wire and bars) by suppliers is also an
option. Peeled wire is available for optimal surface
quality.

CertificatesContinuous recording of process data, calibration of thermocouples with fixed intervals and daily supervision ofprocess data are some of the basics of this standard.

As the world’s largest independent producer oftapered rollers, TN manufactures rollers in a range ofsizes, materials and profiles according to customer
specification. Tapered rollers, typically found inautomotive, wind, rail and industrial applications, carryboth radial and axial loads and are able to carry higher
loads than ball bearings due to the line contact between
the roller and raceway.
