Keyless Shaft Bushings

 ETP keyless bushings are shaft locking devices used to create precise shaft-to-hub connections in high-demanding applications. They are ideal for positioning and locking shaft components in a system, and provide the best alternative to keyways and tapers, which can weaken or cause excess wear to shaft couplings 

 Posi-Lok (PSL) keyless shaft bushings are locking devices that provide a secure shaft-to-hub connection. Most models feature socket-head cap screws for easy tightening and distribution of pressure over the full length of the connection to reduce fretting, corrosion, and backlash.  Posi-Lok bushings are ideal for positioning and locking shaft components in a system, and eliminate the need for keyways, tapers, and tapped holes, which can weaken or cause excess wear to shaft couplings.
