Product Details

Description :

The gear rack is a long, straight bar with teeth along its entire length. The teeth have the same pitch as the pinion gear which engages with it.


Precision Gear Rack And Pinion is a type of linear actuator that comprise a pair of gears which convert rotational motion into linear motion. A circular gear called "the pinion" engages teeth on a linear "gear" bar called "the 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 racks. We are special manufacturing pinion Gear rack, large module CNC gear rack. straight racks, assembly gear rack, Slanting rack, round gear rack .the material refers to C45 Steel, 35CrMo, 42CrMo, stainless steel or according to request.


We are also special to manufacture gear, shaft, sprocket, shaft coupling, rope sheave, belt wheel, bearing block, machine frame, wear resistant parts and non standard machinery parts
