Attaching to a shaft

There are many ways to attach to a shaft (e.g., a motor shaft). Below are a few examples.

• Press fit or interference fit; see also the wikipedia page (note: be careful not to apply axial press forces large enough to damage the motor; the shaft should be supported to avoid this)
• Set screws
• Split clamp

• Keyway

• Epoxy

Some companies that provide shaft couplings:

• Fenner Drives
• McMaster-Carr (split collars, trantorque bushings)
• Stock Drive Products (shaftloc and other couplings)
• Lovejoy
• Ringfeder
