PRODUCT DESCRIPTION

Fenner Drives - Power Transmission - Keyless Locking Devices - B-LOC® Shrink Disc SD10 - Standard Duty


Overview:
  • The B-LOC SD10 Series 24-10 Shrink Disc is an external locking device that provides a high capacity, zero-backlash shaft to hub on shafts ranging from 5/8" to 0.774" in diameter by means of a mechanical interference fit and transmits between 138 ft lbs and 278 ft lbs of torque depending on the specific shaft size.
Description:
  • B-LOC SD10 Series 24-10 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.


  • 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.


  • 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, one of which contracts to squeeze the shaft while the other expands and presses into the component bore.
Notes:
  • Inner rings of all shrink discs are supplied with one lengthwise slit.
  • Shrink discs are available for shafts up to 40" diameter and in a variety of special designs.
  • Maximum shaft sizes listed for Shrink Disc Series SD10 and SD30 re.ect equal section moduli of shaft and hub (maximum shaft diameter = d/1.221).
  • Larger shrink discs for shafts up to 40" diameter are available on request. Please call customer service
