Features

Features 
Versus Traditional Keyed Connections
  • No Backlash due to fit tolerances
  • No impact effect from reversing loads
  • Ability to adjust axial position and angular timing
  • No fretting corrosion due to movement at the fit interface
Versus Traditional Interference Fits
  • Easier and quicker to install
  • Higher contact pressures can transmit greater torques
  • Easy and quick to remove without damaging the shaft or hub - even after years of service
Design Benefits
  • Eliminate cost of machining keyways or splines
  • Reduce the shaft stress by removing keyways or splines
  • Eliminating keyways often allows the use of a smaller diameter shaft
  • Can place anywhere on shaft, and allows for easy angular timing
  • Easy removal without damaging the shaft or hub means easier maintenance for your customer
