Keyless shaft bushings are locking devices that provide a secure shaft-to-hub connection and provide easy and accurate positioning of mounted components. PSL-G keyless shaft bushings provide the highest transmittable torque capacity of our Posi-Lok bushings.  The flangeless design of this model allows the keyless locking device to be recessed within the hub to save space.   
Our PSL-G keyless locking devices are ideal for mounting timing belts, pulleys, cams, gears, and other motion components. Select from models accommodating shafts from 19mm to 120mm in diameter and providing transmittable torque ranging up to nearly 10,000 ft-lb.  Request a quote for PSL-G Posi-Lok keyless shaft bushings or contact us for additional information.

PSL-G Keyless Shaft Bushing Features

PSL-G Posi-Lok keyless shaft bushings feature a mechanical locking double-tapered wedge that is formed as the actuation screws are tightened, pressing the inner sleeve against the shaft and outer sleeve against the hub. The resulting locking connection transmits torque and resists axial forces. Additional features and benefits:
  • Provides a solid connection between the shaft and mounted component
  • Features a simple locking design that eliminates the need for keyways
  • Mounts and tightens quickly and easily using socket head cap screws
  • Has excellent concentricity – only minimal radial and axial runout
  • Designed with 2 tapered rings to increase the contact pressure at the hub and offer a higher transmittable torque capacity
