B1101 B-LOC Shrink Disc 110-10

The B-LOC SD10 Series 110-10 Shrink Disc is an external locking device that provides a high capacity, zero-backlash shaft to hub on shafts ranging from 3-1/8” to 3.547” in diameter by means of a mechanical interference fit and transmits between 9013 ft lbs and 12602 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.

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 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.
