High Torque & High Efficiency
Capable of transmitting high torque due to lack of torque limitation at a low output rotation with a high reduction ratio. Delivers high efficiency and cost savings with less sliding compared to worm types.
Long Service Life
Provides an average of more than 10,000 hours operating life, top level in this class.
The flange mounting dimensions are the same as those of other Japanese manufacturers and compatible with them.
Flexible Installation
Upper and lower mounting pitches of the case are the same, making installation in different application easy.
Wide Reduction Ratio Range
A reduction ratio can be selected from between 1/5 and 1/240.
Outdoor Type Equivalent to IP65
All outdoor types are waterproof, and equivalent to IP65 under IEC standards.
