Standard Ball Reducer BR series
The standard Ball Reducer model.
Its reduction mechanism uses steel balls in the meshing section to achieve Zero-Backlash, high efficiency, and low noise.

Highlights
Supports a Wide Range of Designs
Features a wide variety of output and input shaft shapes to flexibly meet various design needs.
Zero-Backlash
Uses a steel ball in the deceleration mechanism instead of a gear. Eliminates backlash and enables prevision feeding and high-precision positioning through constant rolling contact via preload.
Compact & Simple
Has a reduction mechanism and input/output bearings built into its housing for compactness and ease of installation.
Maintenance-free
Its grease-filled reducer can be used without lubrication for its entire rated life. Also has no mounting position restrictions.
High Efficiency
Its transmission mechanism uses a large number of steel balls to achieve a high-efficiency drive. The rolling contact of the balls is similar to that of a ball screw, allowing extremely light operation and maximized capacity of any motor.
