Features

The FB series component type has pursued flatness and thinness.
It consists of four parts and operates using tha same principle as the cup type of the CSG/CSF series.
The flexspline of the pancake type is shaped like the flexspline of the cup type with a cut bottom and is structured to have an additional circular spline with the same number of teeth as the flexspline.

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