World’s smallest zero-backlash positioner
With the RollerDrive MR Series, a motor is mechanically reduced while maintaining, and stability. An output motion faithful to input control commands can be attained by achieving zero-backlash with our unique preloaded mechanism. This is a revolutionary Ultra Small FA motion control unit, which combines rolling transmission for high-efficiency and elimination of wear, an orthogonal layout of input and output axes for greater compactness, and standard features like a hollow shaft for greater ease-of-use.
