PRODUCT DESCRIPTION

| Description: | |||
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. Rather than creating a radial force on the mounted component, the outer tapered rings are drawn together to generate an axial clamping force. In this way, the mounted component is not subjected to tensile (hoop) stresses. This operating principle also allows narrow components to be mounted with excellent runout. |
