Robot Conveyance

High-power, High-speed, High-serviceability and High-accuracy
Linear Drive Positioning Unit Aiming for the Highest Performance
The Liner Unit is a high-speed, high-power, linear drive unit based on an adaptation of the cam mechanism.
Powered by a servomotor, and featuring a new mechanism that rotates a screw-shaped cam, the Liner Unit travels along a linear
rail, enabling high-speed, long-distance conveyance of heavy loads impossible with conventional mechanisms.
This enables conveyance of heavy materials, large multifunction robots and other production equipment. This exciting nextgeneration linear conveying unit will lead to advanced automation of production lines and improved productivity.

3. High-power

A motor size of 0.75 kW can move a heavy 300-kg load over 4 meters in
only 3.5 seconds.

Liner4 . Excellent durability

Drive power is transmitted by rolling contact for minimal wear andprolonged initial accuracy.
Retains initial repeatability of ±4 μm with virtually no loss even after 10,000
km of travel.
(Repeatability measured after 10,000 km: ±5 μm)

5. MaintenanceBearing

In case of accidents such as unit collisions, the affected bearing or unit canbe replaced separately, allowing quick and easy recovery of the entire
system.

2 . High-speed

Suitable for high-speed motions of 200 m/min or more for drasticallyreduced moving times. The screw rotates perpendicular to the direction oftravel, and has excellent acceleration and deceleration characteristics aswell as small residual vibration during sudden stops, reducing system
cycle times.

High thrust

The integrated drive and rail-guided motion unit solves the "rope jumping"effect caused by deflection in ball screws, and overcomes obstacles
created by supports that are commonly used between rails to prevent
deflection. Simply connect the rails for long stroke applications of 10
meters or longer (length is theoretically unlimited).

Capacity chart
The thrust values in the capacity chart represent the product of the total mass (the mass of the liner including the reducer and motor and the mass of theload) multiplied by acceleration. The speed is calculated based on the gear ratio, motor size, and roller follower life.
The capacity chart is based on a unit mounted with the reducer and servomotor given in the table below. The capacity depends on the actual reducer andservomotor used.
