Taperlock Bushes, Weld Hubs & Shaft Locking Products in the ACT

Taperlock bushes are tapered, non-flanged, split bushings that utilise screws to tighten them to the shaft, thus providing excellent clamping force. These bushes are utilised on pulleys, sprockets, couplings and other associated items to increase the clamping force over standard bored-to-size products that only use a keyway and set screw to lock onto the shaft.

Taperlock bushes have a bore diameter from 10mm or ⅜” up to 125mm or 5″, through a series of 16 different Taperlock sizes. CBS carries a range of products (sprockets, pulleys, couplings etc.) that are used in conjunction with taper lock bushes.

A range of industry-standard weld-on hubs with a shoulder and tolerance outer diameter is available to provide an easy and convenient way to weld a machined hub onto parts such as fan rotors, pulleys, sprockets, impellers and other devices. This allows firm location on a shaft by using a Taperlock bush.

Self-locking assemblies provide reliable, high strength keyless connections by converting locking screw clamp loads into radial contact pressures applied simultaneously to both the shaft and the bore of the mounted component. The resulting zero-backlash mechanical interference fit will accommodate a high torque, thrust, bending and/or radial loads, and unlike other mounting technologies will never wear or pound out, even for high cycle fluctuating or reversing loads.

When the locking unit’s bolts are tightened, plates engage with both the shaft and the inside circumference of the driven component. The locking assembly distributes the applied pressure evenly. No keyways or grubscrews are required with this device.
