A rack and pinion (wheel gear) is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion (reciprocating motion). A circular called “Pinion”, and the engaged teeth on a linear gear bar called “Rack”. Rotational motion applied to the pinion causes the rack to move, thereby, translating the rotational motion of the pinion into the linear motion of the rack.

Advantages of a Rack and Pinions:

• High dynamic performance
• Available in 1045 & 4140 carbon steel and 303, 304 & 316 stainless steels. Special steels on request
• Straight or Helical RH/LH gearing
• Low cumulative error
• Unlimited travel distance
• Higher load capability
• Flexible for custom-made request
• Standard pinions bored to suit
• Maintenance free but only required few drops of light oil
• Constant Stiffness over the complete travel length plus good system performance
• Matching or exceeding the performance and accuracy of other electric and mechanical motion system, and are more efficient

Pinions are customised for your application
