B401200 by Fenner Drives | B-Loc B400 | 200mm | Steel

Overview:
The B-LOC B400 Series 18mm Keyless Bushing provides a high capacity, zero-backlash shaft to hub connection for shafts measuring 18mm in diameter by means of a mechanical interference fit and transmits up to a maximum of 302 Nm of torque.
Description:
B-LOC B400 Series 18mm 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.
Notes:
B-LOC pilot bushings: for series B400 Keyless Bushings to provide pre-centering in applications with either straight through hub bores or narrow hubs. Pilot bushings are supplied in sets consisting of three (3) bushings and three (3) longer screws (replacing plated locking screws). Recommended pre-centering length in installations without pilot bushings. Provide a minimum .001" clearance (hub concentricity depends on fit clearance).
