Superior Movement Achieved with Zero Backlash Technology

RollerDrive Overview

In factory automation equipment, motion control using servo systems is crucial element which greatly affects equipment performance. Naturally, equipment specifications and performance are designed assuming the expected motion is attained. If there are factors such as backlash, insufficient rigidity, or control instability in the motion control section, then output motion will deviate from input control commands. It will be difficult to attain the expected performance. With the RollerDrive™ products, a servomotor is mechanically reduced while maintaining powerful torque, rigidity, and stability. An output motion, faithful to input control command can be attained by achieving zero backlash with our unique preloaded mechanism.
