RPS Pinions

  • RPS Pinions mount to ISO gearbox flanges or smooth output shafts.
  • The rollers are bearing supported for very low friction and long life.
  • Available in coated or stainless steel.

RPS Accessories

  • 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.
