Rack and pinion drive systems compare favorably to other types of linear drives, providing outstanding performance, positioning accuracy, unlimited travel distance, and cost efficiency. Racks and pinions are used in hundreds of applications such as packaging machines, conveying devices, printing equipment, and automated machinery.

QTC METRIC GEARS stock gear racks are manufactured for high-precision linear motion applications. Racks are available in Modules 0.5 thru 10 and lengths ranging from 100 to 2000 mm. Offered in steel, stainless steel, and plastic, characteristics include high precision, abrasion resistance, high strength, long life, rust resistance, low noise, and cost efficiency. Lubrication is the key to ensuring long life and ability to reach high speeds. The correct amount of grease is usually applied automatically resulting in little maintenance.
