Bushings firmly connect components to a shaft. Three main types of bushings are quick-detaching, taperlock, and keyless. Both quick-detaching and taperlock bushings have tapered sides and a split. This design allows them to obtain very high clamping forces. They also contain a keyway that connects to the shaft using a key. Keyless bushings do not utilize a keyway or machined keyseat in the shaft. As a result, they can be used with smaller shafts. The absence of keyways and tapers also decreases stress on the bushing.
