PRODUCT DESCRIPTION

Fenner Drives - Power Transmission - Keyless Locking Devices - B-LOC® BCH20 - Light Duty - Metric


Overview:
  • The B-LOC BCH20 Series 60 mm Compression Hub is an external locking device that provides a way to mount component(s), without the need for a hub, to a 60 mm diameter shaft. This is accomplished by creating a mechanical interference fit that will transmit 1445 Nm of torque.
Description:
  • 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.


  • 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. 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.
