Precision gears are the type of gears that provide accurate motion, even when subjected to higher loads. It is a necessary component for many industrial equipment, such as gauges, measuring devices, automation instruments and industrial machining equipment.

A precision gear could be a spur gear, a helical gear, a bevel gear or a worm gear. Suppliers of precision gears provide precision gears of different material such as aluminum, brass, bronze, steel and plastic. Some industries that use precision gears are the aerospace, defense, oil and gas, textile and mining industries.

Some important parameters you must consider before buying a precision gear are:

1. Loads acting on the precision gears
2. Type of application
3. Transmission ratio (or gear ratio)
4. Dimensions of precision gears such as pitch, module, pressure angle and diameters
