• Use as is to make shaft smaller
  • Keyways provide added torque capacity and fixed shaft phasing
  • Fully machineable to change size or configuration
  • Eliminates need for complete shaft replacement.
  • No welding required.
Shaft Adapters are designed to modify, extend or repair an existing shaft and provide a fully machineable male output shaft with minimum effort and expense. Standard keyways provide added torque capacity and fixed shaft phasing.

For use on standard hardened round shafts, Shaft Adapters are precision machined, non-marring, easy to adjust, with high clamping power.
