Keyless shaft bushings provide a solid hub-to-shaft connection and are ideal for mounting timing belts, pulleys, cams, gears, and other motion components.
 
Our PSL-K Series Posi-Lok keyless shaft bushings offer high torque capacity and feature a flanged design that better exposes the compression screws to simplify installation and disassembly. The small ID and OD sleeve dimensions allow for smaller components to be mounted for space, inertia, weight, and cost savings.  PSL-K keyless locking devices also support smaller shaft sizes and are available in both metric and some inch sizes with transmittable torque ranging up to 553 ft-lb.

PSL-K Keyless Shaft Bushing Features

PSL-K Posi-Lok keyless shaft bushings feature a simple locking design that does not require the use of keyways. Tightening of actuation screws draws two opposing conical tapers against their mutual contact surfaces. This forces the inner and outer sleeves to expand against the shaft and hub, fastening components to the shaft.  The resulting locking connection transmits high torque and resists axial forces. Additional features include:
  • Socket head cap screws tighten quickly and easily for fast mounting
  • Excellent concentricity – only minimal radial and axial runout
  • Small ID / OD sleeve dimensions allow a smaller component to be mounted, saving on the moment of inertia, cost, and weight
  • Compatible with smaller shaft sizes
