6410044 by Fenner Drives | Trantorque Mini | 7/16" | Steel

Overview:
The Trantorque Mini Series 7/16" Keyless Bushing provides a high capacity, zero-backlash shaft/hub or coupling connection of mounted components to shafts measuring 7/16" in diameter by means of a mounted mechanical interference fit and transmits up to 669 inch lbs of torque.
Description:
Trantorque Mini Series 7/16" 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. This product has exceptional concentricity and the ability to accommodate bending loads. The Trantorque Mini Series has limited axial movement during installation. All Trantorque units use a single hex nut for speed and simplicity of installation. Best Suited For: Small shaft applications where speed and simplicity of installation and repositioning are critical. Exceptional concentricity and ability to accommodate bending loads Limited axial movement during installation All Trantorque units use a single hex nut for speed and simplicity of installation Features of Fenner Drives Keyless Bushings: Ability to transmit higher torques than keyed connections 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.
