PRODUCT DESCRIPTION

Fenner Drives - Power Transmission - Keyless Locking Devices - B-Loc® B112 - Steel - Heavy Duty - Metric


Overview:
  • The B-LOC B112 Series 24mm Keyless Bushing provides a high capacity, zero-backlash shaft to hub connection for shafts measuring 24mm in diameter by means of a mechanical interference fit and also transmits up to a maximum of 755 Nm torque.
Description:
  • B-LOC B112 Series 24mm Keyless Bushings provide a zero-backlash frictional connection that will never wear or pound out and can accommodate a high torque, thrust, bending, and/or radial loads. Their wide, double taper design enhances torque transmission and bending moment capacity while maintaining exceptional concentricity with thru-bored hubs. There is no axial movement during installation. The B-LOC B112 Series eliminates the need to hold the shaft or lock machine while applying installation torque, making for fast and easy component repositioning. Since the B-LOC B112 Series Keyless Bushings do not have a flange, the external diameter along the unit's entire length is the same, therefore allowing the unit to be completely inserted into the component bore for flushed or recessed mounting. This series is also self-centering and RoHS compliant.


  • Best Suited For: Applications that require a recessed installation of the bushing with no axial movement of the mounted component relative to the shaft during tightening.


  • Wide, double taper design for enhanced torque transmission and bending moment capacity
  • Exceptional concentricity with thru-bored hubs
  • No axial movement during installation
  • Self-centering
  • Eliminates need to hold shaft or lock machine while applying installation torque
  • Recessed installation without the need for a counter bore
  • RoHS compliant


  • Features of Fenner Drives Keyless Bushings:
  • Ability to transmit higher torques
  • True zero-backlash
  • Less equipment downtime
  • Ability to mount over existing keyways
  • Complete axial and radial adjustability
  • Simple installation, adjustment and removal


  • All Fenner Drives keyless locking devices operate using the simple wedge principle. An axial force is applied- by either a hex nut (Trantorque) or a series of annular screws (B-LOC)- to engage circular steel rings with mating tapers. The resulting wedge action creates a radial force on the tapered rings, one of which contracts to squeeze the shaft while the other expands and presses into the component bore.
