Features

The FR series component type is a flat, thin type for high torque.
It consists of four parts like the FB series and operates using the same principle as the cup type.
It is basically structured in the same way as the FB series and supports high torque capacity by arranging the wave generator bearings in two lines and widening the tooth width of the circular spline and the flexspline.

      • Flat shape type
      • High torque capacity
      • Compact and simple design
      • High positioning and rotational accuracies
      • Coaxial input and output
