Speed Reducer Manufacturers

Speed reducers, alternatively called gear heads or gear boxes, are used to decrease rotating speed, which is realized through an increment in torque and a decrement in output speed. Input, output shafts, and a set of gears are the constituents of the gear heads. The reducer receives input power from any source like motor and performs the task of converting this power into an output speed of lower magnitude; this lower-magnitude speed is transmitted to the connected load via an output shaft. These devices are employed in a variety of applications including printing presses, automation equipment, compressors, conveyors, pumps, generators and robotic applications.

Bristol Instrument Gears, Inc. (Forestville, CT)


AutomationDirect (Cumming, GA)


Gearboxes, also known as enclosed gear drives or worm gear speed reducers, are mechanical power transmission drive components that can drive a load at a reduced fixed ratio of the motor speed. The output torque is also increased by the same ratio, while the horsepower remains the same (less efficiency losses.) A 10:1 gearbox outputs approximately the same motor output horsepower, motor speed divided by 10, and motor torque multiplied by 10. Similar performance metrics are provided by 20:1 gearboxes and other ratios.
