  • Provide high strength connection between components and shafts
  • Keyless
  • Transmit very high axial and torque loads
  • Easy to install
  • Will not damage shafts or components
    •
PowerRing™ Shaft-Hub Locks provide a keyless, extreme high strength connection between components and round shafts. They feature a smooth, non-marring bore which contracts securely onto a shaft while expanding the OD tightly into the I.D. of a hub. Fully adjustable, they are balanced to minimize vibration at high speeds, and prevent backlash damage caused by heavy loads.

They are easy to install by tightening the locking bolts around the device’s face. When these bolts are tightened, multiple internal taper rings produce the frictional forces necessary to join the shaft and hub allowing the transmission of high torque and axial loads.

Simplifying the timing of matched components, PowerRing™ Keyless Shaft-Hub Locks are ideal for mounting gears, sprockets, pulleys and related devices.
