The B-LOC B400 Series 75mm Keyless Bushing provides a high capacity, zero-backlash shaft to hub connection for shafts measuring 75mm in diameter by means of a mechanical interference fit and transmits up to a maximum of 6300 Nm of torque.

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.

B-LOC B400 Series 75mm 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.Self-releasing double taper design permits simple adjustment and removal. No axial movement during installation. Recessed installation without the need for a counterboreNote: This product is not self-centering but Fenner 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 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 removalAll Fenner 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.
