Racks

A rack and pinion is a type of linear actuator that consists of a bar with teeth on one face (the rack) and a matching toothed wheel (the pinion).

When the pinion’s teeth mesh with the rack’s teeth, the rotational movement of the pinion is converted into linear motion along the rack. This mechanism is commonly used in various applications, including vehicle steering systems, rack railways, robotics, water gates, actuators, machine tools, and presses, where it effectively transforms rotational motion into precise linear movement.

Rack and pinion gears are available in sizes ranging from 0.5 to 8.0 MOD/4 to 32 DP and can be made from a variety of materials to suit different needs. Options include steel EN8 (080M40/080M46/212A42), which can be normalized or equivalent, stainless steel, and materials with induction or flame hardening. Other materials include moulded nylon 6 (PA6) with 30% glass filling, white HOSTAFORM® C, DURACON® M25-44, and moulded acetal/DELRIN® with machined teeth.

Intermediate sizes and custom racks can be produced according to specific drawings.
