The TCG Cam Rack&Roller Pinion achieves light rotational-to-linear motion transmission through rolling contact between the rollers of the meshed pinion and the rack tooth surface.

This Cam Rack & Roller Pinion is made of stainless steel exactly taking over the features of Zero-backlash, high accuracy, low friction, low dusting, etc. of TCG Series. This product has excellent corrosion resistance and anti-rust effect.

A Zero-BacklashBall Reducer with roller pinions assembled. Its roller pinion set type simplifies the design and assembly processes, contributing to improved efficiency. This reducer can also be combined with TCG series cam racks and cam rings for high-precision positioning.

The internal gear of this differential reducer has a trochoid tooth profile, which enables high-precision positioning while maintaining the strength to withstand the maximum working load of the TCG series.

The combination between the cam ring formed by the trochoidal tooth profile and the roller pinion enables Zero-Backlash, high-precision positioning, and light rotational transmission.

A circular arc ring-type cam ring with a trochoidal tooth profile. Manufacturing the ring in circular arcs makes it possible to accommodate an infinite radius with the minimum space required, realizing large-diameter hollow shapes.

A Zero-Backlash reducer with high rigidity and large hollow diameter. Integrates a cam ring, roller pinion, and a Ball Reducer as a single unit, reducing design complexity and assembly man-hours.

The RGU Series has a circular arc ring model lineup.
