Non-backlash Roller Cam Series / AR Series

1. Highly precise prepressing radial bearings with vapor-pressure type brake locking are used to increase the locking pressure, thus ensuring resistance to cutting forces.
2. An extremely accurate roller cam is highly efficient in any driving location, easily adjusts back clearance, and can rotate on line with a CNC machine or match a single-shaft controller for processing.
