Zero Backlash Gear Systems

The Roller Pinion Gear System (RPG) is based on an innovative pinion consisting of bearing-supported rollers and a unique tooth profile. Solutions including gears, gear segments and geared bearings can be configured to fill your needs. This unique drive system provides very high positional accuracy, zero backlash, no cumulative error, low-velocity ripple, very high speeds, high rigidity, low noise, low maintenance, corrosion resistance, and long life. This opens up new machine design possibilities and provides the capability to achieve much higher levels of performance.

Geared Bearings

Combining a full ring gear and a high capacity cross roller bearing, the Geared Bearing solution is ready to be integrated into a machine. The standard product offering is available in a large range of sizes and ratios. Based on the Roller Pinion Gear technology, the product offers high accuracy, high load capabilities and zero backlash.

Gears

Gears

With external or internal teeth, a selection of standard and custom gears are available. Based on the Roller Pinion Gear technology, ring gears offers high accuracy with zero backlash.


Gear Segments

Gear Segments

Roller Pinion gear segments have the versatility to create a range of arc lengths or full rings. An alignment tool allows for precise joining of more than one segment. With external or internal teeth, the Roller Pinion Gear technology offers very high levels of rotary accuracy, zero backlash.


Pinions, Pre-loaders, and Adapters

Pinions, Pre-loaders, and Adapters

Roller Pinions are used with RPS rack and gear sets. The rollers are bearing supported for very low friction and long lives. RPS Preloaders precisely move the pinion into the rack and establish a small preload. RPS Flange Adapters allow flange mount pinions to mount to one reducer frame size larger than they would directly bolt to.
