These gear racks convert rotary motion into precise linear travel, forming the heart of steering systems, linear actuators and positioning stages. The teeth are milled to an exact pitch along the bar so that the mating pinion advances the rack smoothly and accurately, without cumulative error building up along its length.
Straightness and tooth alignment are controlled along the whole rack, which keeps the pinion meshing evenly and prevents tight spots or backlash at the ends. The result is dependable, repeatable linear motion for steering and automation applications. Send your travel length and pinion module, and we will recommend a rack and pinion combination for accurate linear motion.
Key Features
- Accurate Tooth Pitch: Precise pitch along the bar prevents cumulative positioning error.
- Smooth Linear Travel: Even meshing gives quiet, consistent rack-and-pinion motion.
- Controlled Straightness: Alignment is maintained along the rack to avoid tight spots.
- Low Backlash: Consistent tooth form keeps play minimal for accurate positioning.
- Hardened Options: Heat treatment is available for wear resistance under sustained load.
- Custom Lengths: Racks cut and drilled to suit your steering or actuator design.
