Shaft Collars

  • Related terms: locking collars, set screw collars, clamp collars, split shaft collars
  • Rings that clamp or screw onto a shaft to locate components, act as a mechanical stop or limit axial movement. Available in solid set screw and split clamp designs, they are used in gearboxes, conveyors, motors and general machinery assemblies.

Drivelock Bushes

  • Related terms: drive lock bushes, drivelock bushings, shaft locking bushes, drive bushes
  • Bushes designed to lock drive components such as pulleys, sprockets and gears securely onto a shaft for reliable torque transmission. They offer a quick, accurate way to mount and remove drive parts while reducing the need for machining.

Keyless Bushes

  • Related terms: keyless bushings, keyless shaft bushes, friction lock bushes, keyless hubs
  • Bushes that clamp a hub onto a shaft using friction rather than a keyway, spreading the load evenly around the shaft. They eliminate the stress points and wear caused by keys, allow precise positioning and make fitting and removal straightforward.

Keyless Locking Elements

  • Related terms: locking assemblies, keyless locking devices, shaft locking elements, ring feder elements
  • Heavy-duty locking assemblies that use tapered rings and clamping screws to create a strong, backlash-free connection between shaft and hub. Suited to high torque and reversing loads, they are used in conveyors, gearboxes, printing machinery and heavy industrial drives.

Tapered Locking Bushes

  • Related terms: taper lock bushes, taper bushes, taper bore bushes, taper lock bushings
  • Split, tapered bushes that fit into matching tapered-bore pulleys, sprockets and couplings, clamping them tightly onto the shaft when the screws are tightened. Available in a wide range of bore sizes, they allow one component to suit different shafts and make installation and removal quick and easy.
