Roller Drive FR Series

The roller cam consists of an input cam shaft and a roller turret.
The roller cam is designed with rolling contact, featuring high rigidity, high speed, and outstanding durability.
Engagement between the roller and cam are preloaded to fully eliminate ultra-high precision feature.
Besides, with rolling contact to transmit kinetic energy, energy consumption during drive can be dramatically reduced. This enables the roller cam to achieve over 90% of transmission efficiency.
