High Performance Rack & Pinion Actuators

All RPA models consist of a solid, one-piece aluminum housing containing a gear rack and pinion gear. By driving the pinion, rotational motion is converted to linear motion; by driving the unit axially, linear motion can be converted to rotational motion. In either mode, these rack and pinion linear actuators deliver superior performance minimal backlash (as little as 2° backlash).

Our rack and pinion gearboxes feature relatively short strokes, with standard 10mm to 30mm options available. Custom stroke lengths are available to meet your specialized requirements. RPA actuators deliver up to 60 Kg max load output (varies by model).
