Quick-Disconnect (QD) Bushings
Clamp On
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.

Hub-Mount Screw-Clamp Bushings
Transfer torque directly from a shaft to a hub. These bushings install over your hub to mount a sprocket, pulley, or gear to a shaft at the same time. Common in industrial gearbox applications, they can also connect a hollow shaft over a solid shaft. As screw-clamp bushings, they're good for shock loads. When you tighten the included clamping screws, the outer rings compress against a sprocket, pulley, or gear in between them, causing the inner rings to tighten around the shaft.

(Each Component Sold Separately)
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.
