Nexen Group, Inc. offers a roller pinion system that is a durable alternative to rack and pinion, ball screw, and belt drive technology.

A stainless steel version of the patented precision roller pinion system (RPS) is available. The Nexen RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is also extremely quiet, and 99% efficient. Stainless steel makes the system extremely corrosion resistant, with a long life of up to 36 million meters.
