About our Zero Backlash Geared Bearings

Based on Nexen's innovative Roller Pinion technology, the Roller Pinion System Geared Bearing (RPS-GB) comes complete with a precision zero backlash gear mounted and dialed in on a precision grade high capacity bearing.

Unlike some cam-driven systems, the Precision Ring Drive Systems can start and stop at any incremental position, allowing for maximum acceleration or deceleration at any point without the risk of damage. 

With many possible sizes and gear ratios, all with zero backlash, the Nexen Geared Bearing can be incorporated into any precision rotary motion control application.
