TTQM1832 by Fenner Drives | Trantorque OE | 18mm | Steel

Overview:
The Trantorque OE Series 18mm Keyless Bushing provides a high capacity, zero-backlash shaft/hub or coupling connection of mounted components to shafts measuring 18mm in diameter by means of a mounted mechanical interference fit and transmits up to 221 Nm of torque.
Description:
Trantorque OE Series 18mm 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. While maintaining a minimal OD/ID ratio, The Trantorque OE Series Keyless Bushings also have exceptional concentricity and the ability to accommodate bending loads. They also have 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.
