ETP-POWER® Keyless Shaft Bushings
Keyless shaft bushings provide a secure shaft-to-hub connection and are ideal for positioning and locking shaft components in a system. Their keyless design allows for quick and easy adjustment and prevents excessive stress and wear on shaft components.
ETP-POWER keyless shaft bushings from Zero-Max consist of a double-walled hardened steel sleeve and flange filled with a specially designed pressure medium. The flange contains a single actuation screw piston with a seal that is used to pressurize and maintain pressure in the connection. The design is optimized to provide higher radial load capacity than the other single-screw models. Also, in the flange are two pre-machined bores that can be used to attach ETP-POWER to the mounted components when the connection is not pressurized.

Features and Benefits of ETP-POWER Keyless Locking DevicesETP-POWER keyless shaft bushings are easily adjusted and handle a full range of shaft size and transmittable torque ranges. When the actuation screw is tightened, the double-walled sleeve expands uniformly against the shaft and hub and creates a rigid connection. Uninstalling is done by loosening the screw which returns the ETP-POWER to its original dimensions. It can then easily be removed.
Additional features include:
- High radial load capacity
- Fast mounting/unmounting with only one screw
- Small built-in dimensions
- Radial tightening of the screw saves space along the shaft
- Accurate positioning, no axial movement when mounting
- Excellent concentricity even after several mountings
- Handles temperatures ranging from 32°F to 158°F
