A worm gear reducer is one type of reduction gear box which consists of a worm pinion input, an output worm gear, and features a right angle output orientation. This type of reduction gear box is generally used to take a rated motor speed and produce a low speed output with higher torque value based on the reduction ratio. They often can solve space-saving problems because the [worm gear reducer](https://www.torquetrans.com/worm-gear-speed-reducer) is one of the sleekest reduction gearboxes available due to the small diameter of its output gear.

Worm gear reducers are also a popular type of speed reducer because they offer the greatest speed reduction in the smallest package. With a high ratio of speed reduction and high torque output multiplier, it's unsurprising that many power transmission systems make use of a [worm gear reducer](https://www.torquetrans.com/worm-gear-speed-reducer). Some of the most common applications for worm gears can be found in tuning instruments, medical testing equipment, elevators, security gates, and conveyor belts.

**SW-1 and SW-5**

 Torque Transmission offers two sizes of worm gear reducer, the [SW-1 ](https://www.torquetrans.com/worm-gear-speed-reducer)and the [SW-5](https://www.torquetrans.com/right-angle-speed-reducers) and both are available in a range of ratios. The SW-1 ratios include 3.5:1 to 60:1 and the SW-5 ratios include 5:1 to 100:1. Both of these options are manufactured with rugged compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that is also compact, non-corrosive, and non-metallic.

**Features**

 Our worm gear reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox designs, making them ideal for demanding applications.
