Quick-Disconnect (QD) Bushings
The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

Vibration-Damping Flexible Shaft Couplings
Coupling Shown
Assembled
A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock.
A complete coupling consists of two hubs, one tire, and two quick-disconnect bushings.
Quick-disconnect bushings are easy to install and remove. Tighten their cap screws to secure them to your shafts. For information on quick-disconnect bushing styles, see Quick-Disconnect (QD) Bushings.
