Developed for complex environments
A rack and pinion system gives the ability to transfer rotary to linear motion, with all the accuracy expected of a geared system. Reliance Technology Racks and Pinions are an ideal choice for use in complex environments. Typical markets for racks and pinions include defence and life sciences.
Racks are available in two types – solid round and tubular – and can be manufactured from ground stainless steel or ground hardened stainless steel. Ground racks are a more accurate solution than hobbed racks and can be used for both measurement and actuation. In general, the smaller pitches (1 mm) suit measurement applications as the smaller pinion diameter gives higher linear resolutions. The larger pitches (2 mm and 2.5 mm) allow for a higher load capacity. For most applications the rack can be used for both the feedback and the actuation; however, in very precise applications it is best to us a non-drive section of the rack for feedback, alternatively a separate rack can be used.

Key Features and Benefits
Accurate conversion from rotary to linear motion.
Available with a choice of accuracies, pitches, and lengths.
Suitable for use in demanding applications in complex environments.
Can be manufactured from ground stainless steel or ground hardened stainless steel.
Round Racks
We offer two types of rack – solid round racks and tubular racks. These are available plain or hardened and can be supplied with a choice of accuracies, pitches, and lengths, plus the facility to provide modifications such as flats, journals or custom ends.
Solid Round Racks
Solid round racks are a more flexible alternative to rectangular racks when it comes to mounting. They can be used, for example, in XY stages.
Tubular Racks
Tubular racks allow for the passage of fluids, fibre-optics, gasses etc., making them ideal for medical and scientific applications, such as laboratory automation pick and place mechanisms.
Pinions
Pinions are available plain or anti-backlash, also with a choice of accuracies, pitches, bore sizes, alternative materials and coatings. Our pinions are supplied to a minimum quality class of AQ10, but the level of quality can be chosen to suit your requirements. Higher accuracies are available. For more information, please download the Reliance Technology Racks and Pinions Data Sheet.
Racks & Pinions Materials and Finishes
Reliance Technology Racks and Pinions are manufactured from ground stainless steel or ground hardened stainless steel though other materials are available. Hardened pinions provide longer pinion life, higher load capacity and higher thrust. For more information, please download the Reliance Technology Racks and Pinions Data Sheet.
