Roller-Pinion System

The RPS rack is a roller-pinion system designed to eliminate the shortcomings of linear-drive systems. It replaces spur-gear teeth with bearing-supported rollers that engage a rack-tooth profile. The rollers eliminate sliding friction with smooth rolling friction for a 99%-efficient rotary to linear-motion conversion.

Two standard factory lengths per size create runs of any length. Full lengths are around 1 m in length and half-lengths around ½ m in length, depending on tooth pitch. The RPS features positional accuracy up to 30, 50 and 80 μm to accommodate any application’s precision requirement.
