Product Info Reducers
Reducers are mechanical device that outputs power obtained from the output shaft of a power source such as a motor by reducing the rotational speed using gears.
The ratio of the number of gear teeth on the input and output sides is the reduction ratio, and the torque at the output shaft is inversely proportional to the reduction ratio.
Our line-up includes three gear types - helical gears, hypoid gears and worm gears - which can be selected according to the motor specification, shaft arrangement (parallel or right-angle shaft) and output shaft shape (solid or hollow) to suit the purpose.

※Self-Locking: This is a function of the worm gear that the input shaft side cannnot be turned from the output shaft side.
Generally, reduction ratio is 1/60 as a single-step reduction.
