High-Misalignment Tire Couplings
 |
With a large, flexible rubber tire, these withstand the highest misalignment of any coupling while reducing vibration. For a complete coupling, select two hubs, one tire, and two bushings. Choose components of the same trade size to ensure they'll fit together.
Hubs
 |
The metal body mounts onto shafts to transmit torque from one shaft to the other through the flexible center.
Iron and Steel Hub—Best for dry environments, since moisture will cause these hubs to rust.
Clamp-On Shaft Mount—Grip shafts evenly without marring them and hold tighter than set screws. Tighten the clamping screws to secure.

Tires
 |
Fit these highly flexible rubber tires over the two hubs. They transmit torque, compensate for misalignment, and isolate shock and vibration.
Buna-N—Highly tear resistant.
Taper-Lock Bushings
 |
Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing trade number. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.
Quick-Disconnect (QD) Bushings
 |  |
Clamp-On Shaft Mount |
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 trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
