Roller Drive FR Series 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.
