XOMOX® Rack and Pinion Pneumatic Actuators

The unique features of XOMOX® XRP Pneumatic Rack & Pinion Actuators include a balanced pinion which does not require an external clip to prevent the pinion from blowing out. Optimally positioned, graphite infused, self-lubricating Teflon sliding bands on the piston ensure low friction operation with minimal risk of piston tilt, resulting in low wear.

Features And Benefits

  • Patented, pressure balanced shaft prevent axial forces acting on the bearings. This results in high reliability, long life and low wear.
  • Robust anodized aluminum bodies ensure even expansion under thermal influences; no jamming of the piston and a high level of corrosion protection.
  • Self lubricating piston guide bands prevent piston tilt under load, provide longer service life due to low friction, with no maintenance required.
  • Compact design allows extensive direct mounting orientations.
