B0551 B-LOC Shrink Disc 55-10

The B-LOC SD10 Series 55-10 Shrink Disc is an external locking device that provides a high capacity, zero-backlash shaft to hub on shafts ranging from 1 1/2” to 1.773” in diameter by means of a mechanical interference fit and transmits between 1014 ft lbs and 1707 ft lbs of torque depending on the specific shaft size.

Best Suited For: Applications needing to connect a hollow shaft over a solid shaft. Commonly used on hollow output shaft gear boxes or flange couplings.B-LOC SD10 Series 55-10 Shrink Discs are external locking devices that provide a zero-backlash frictional connection that will never wear or pound out and can accommodate high-torque, thrust, bending, and/or radial loads. The SD10 Series Shrink Discs are also extremely concentric and maintain a well-balanced mechanical interference fit. There is no axial movement during installation of this product.Extremely concentric and well-balanced mechanical interference fit. No axial movement during installationFeatures of Fenner Drives Keyless Bushings: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 removalAll 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.
