Thinning

Thin cross roller bearings are used at the output shaft to achieve product thinning and meet the requirements of relevant design schemes.
Zero backlash

The deceleration structure uses steel balls instead of traditional gears. By maintaining constant rolling contact through preloading, eliminating backlash and achieving high precision.
Compact and concise structure

The deceleration structure and input/output bearing parts are built into the housing, making installation simple.
Widely adaptable

There are various shapes and styles of input and output shafts to choose from, which can cope with various motor models without installation direction restrictions. They can be installed immediately after purchase.
maintenance-free

Internally sealed with lubricating grease, no maintenance or lubrication is required within the rated lifespan.
high efficiency

By utilizing the rolling contact and multiple meshing of steel balls, a light and efficient drive is achieved, fully unleashing the motor's capabilities.
