PRODUCT DESCRIPTION
Fenner Drives - Power Transmission - Keyless Locking Devices - B-Loc® B - 400 - Steel - Inch
|
Overview: |
- The B-LOC B400 Series 3/4" Keyless Bushing provides a high capacity, zero-backlash shaft to hub connection for shafts measuring 3/4" in diameter by means of a mechanical interference fit and transmits up to a maximum of 234 ft lbs of torque.
|
|
Description: |
- B-LOC B400 Series 3/4" 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.
