The B-LOC SD10 Series 140-10 Shrink Disc is an external locking device that provides a high capacity, zero-backlash shaft to hub on shafts ranging from 4” to 4.514” in diameter by means of a mechanical interference fit and transmits between 19648 ft lbs and 26440 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 140-10 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 installation Features 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 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,
