Rack & Rack Pinions

Precision engineered racks and pinions from Perfect Gear Industries are available in both diametrical and metric module pitches. Rack and pinion can be used to provide a complete product, including bored holes, turned and milled integral shafts, and drilled and tapped hole patterns. A wide range of materials, metal finishes, and heat treat options are also available. Racks and pinions are used to convert rotary and linear motion. The rack is the flat, toothed part, while the pinion is the gear. Rack and pinion can convert from rotary to linear or from linear to rotary. The diameter of the gear fixes the speed, which the rack moves as the pinion turns. These are typically used in the steering system of cars to convert the rotary movement of the steering wheel to the side-to-side motion in the wheels. Rack and pinion gears give a positive motion especially when compared to the friction drive of a wheel in tarmac. Perfect Gear Industries is one of the leaders amongst manufacturers, suppliers and exporters of a comprehensive range of industrial gears, couplings, pinions, clutch plates, rolls, and more.
