Selection Guide 　Reducers

・Four types of gears are available depending on applications.

・Helical Gear
(Low Noise ・High Efficiency )

・Hypoid gear
(Extremely compact )

・Worm gear
(Practically silent ・Self-Locking ※)

・Bevel gears
(High Efficiency ・Abundant variations )

※What is self-locking

This is a function of the worm gear that the input shaft side cannot be turned from the output shaft side. Generally, reduction ratio is 1/60 as a single-step reduction.

・Selecting conditions will display the compatible series.
