QD Bushing Series F 3 in Bore

The TB Wood's QD bushing is a quick-detachable steel component designed for power transmission assemblies. It fits a 3 in keyed shaft and uses a split flange for straightforward mounting and removal without special tools.

Upgrades from pressed-on or set-screw hubs

This bushing replaces hubs that require heating or hammering for installation. The taper of 3/4 in per foot and three included SAE Grade 5 cap screws on a 5.63 in bolt circle provide a secure, repeatable fit when frequent changes are needed.

Suits maintenance crews

It suits teams that standardise on Series F dimensions and need a 3 in bore with a 4.438 in bushing diameter. Shops using a different bore series or a non-keyed shaft should look at another bushing type.
