PRODUCT DESCRIPTION

Fenner Drives - Power Transmission - Keyless Locking Devices - B-Loc® B - 400 - Steel - Inch


Overview:
  • The B-LOC B400 Series 3/4" Keyless Bushing provides a high capacity, zero-backlash shaft to hub connection for shafts measuring 3/4" in diameter by means of a mechanical interference fit and transmits up to a maximum of 234 ft lbs of torque.
Description:
  • B-LOC B400 Series 3/4" Keyless Bushings provide a zero-backlash frictional connection that will never wear or pound out and can accommodate high-torque, thrust, bending, and/or radial loads. Their self-releasing double taper design permits simple adjustment and removal and there is no axial movement during installation. Since the B-LOC B400 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.


  • 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.


  • Self-releasing double taper design permits simple adjustment and removal
  • No axial movement during installation
  • Recessed installation without the need for a counterbore


  • Note: This product is not self-centering but Fenner Drives offers pilot bushings that provide pre-centering when required. The pilot bushings are supplied in sets of three (3) bushings and three (3) longer screws (replace plated locking screws).

    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.
