The B-LOC BCH20 Series 1" Compression Hub is an external locking device that provides a way to mount component(s), without the need for a hub, to a 1" diameter shaft. This is accomplished by creating a mechanical interference fit that will transmit 97 ft lb of torque. Best Suited For: Applications mounting thin components or components made from materials that do not perform well under tensile (hoop) stresses. The most common use is mounting flat chain sprockets to a shaft. The B-LOC BCH20 Series 1" Compression Hub is an external locking device that provides a way to mount component(s) without the need for a hub. This is accomplished by creating a mechanical interference fit that will never wear out. Features of Fenner Drives Compression Hubs: • No Hub Required • Ability to transmit high torques • True zero-backlash • Less equipment downtime • Ability to mount over existing keyways • Complete axial and radial adjustability • Simple installation, adjustment and removal • Extremely concentric and well-balanced mechanical interference fit • No axial movement during installation The basic function of B-LOC Compression Hubs is similar to other Fenner Drives Keyless Locking Devices. Axial force is applied by tightening a series of screws to engage sets of mating tapered rings. The inner tapered rings create radial force on the shaft resulting in a high pressure frictional connection. However, the difference from other keyless locking devices arises in how B-LOC Compression Hubs engage the mounted component.
