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
