SK-Style QD Bushing for Sheaves & Pulleys — Ductile Iron, Keyed
The SK-style QD (Quick-Disconnect) bushing provides a fast, secure way to mount SK-bored sheaves, sprockets, and pulleys onto a drive shaft. Its tapered, flange-split design draws tight as the cap screws are torqued, locking the component concentrically to the shaft for true running and easy removal — no pullers required.

- Supplied with three Grade-5 cap screws plus a set screw over the keyway for added holding power
