Performance by Zero-Backlash Technology
The main part of the RollerDrive mechanism consists of an input shaft and an output turret in which roller followers are embedded. An integral cross-roller bearing supports the output turret with minimal run out.

Preloaded roller followers contact the input rib surfaces with a wedge-shaped cross section, which can be adjusted by moving the input axis, to eliminate backlash completely. No backlash means superior precision and stiffness for both CW and CCW rotation, as shown on the diagram to the right.

Even with preload and zero-backlash, the needle-bearing type roller followers transmit power by rolling rather than sliding making it possible for the RollerDrive to achieve an outstanding efficiency of 90% or more and life-time wear-free durability. All parts are made from only qualified alloy steels, and machined and ground with our ultra-precision machining system.

Be Distinctive
RollerDrive product series are widely used in various industries that require the highest in performance levels. Machine tool companies are not an exception and RollerDrive technology is already being applied to the world’s leading machine tools.
