Keyless Bushing for 1/2 in Shaft

The Fenner Drives 6410050 is a flange-type keyless bushing designed for a 1/2 in bore and 7/8 in outside diameter. It suits maintenance teams and machine builders who need a backlash-free shaft-hub connection without keyway machining.

Capacity and Headroom

The single-nut locking assembly transmits up to 737 ft-lb of torque while generating 17,864 psi hub contact pressure. Its 1 in overall width and oil-dipped steel finish handle shock loads in conveyors and packaging lines, but the fixed bore limits use to 1/2 in shafts only.

Critical Fit Specification

Outside diameter tolerance is held to +/- 0.0015 in, so the mating hub bore must be machined to match. Verify this tolerance before ordering; the bushing cannot accommodate larger or smaller shaft sizes.
