Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed. As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Stainless steel bushings are corrosion resistant for use in harsh environments.

Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads. When you tighten the included clamping screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.

Corrosion-Resistant Flanged Screw-Clamp Bushings

Made from stainless steel or plated with nickel, these bushings resist corrosion. A mounting flange prevents movement during tightening. As screw-clamp bushings, they're good for shock loads. When you tighten the clamping screws, the bushing's inner sleeve tightens onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Nickel-plated steel bushings have good corrosion resistance in wet environments. However, the plating may begin to flake with long-term use.
Stainless steel bushings have excellent corrosion resistance and can withstand prolonged exposure to moisture.

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.

Insert these nickel-plated steel bushings into the bore of your sprocket for flush or recessed mounting in wet environments. When you tighten the included clamping screws on these bushings, their inner sleeve contracts onto the shaft and their outer sleeve expands to hold your sprocket, pulley, or gear. This keeps bushings from slipping during sudden starts and stops.

A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit. Made of spring steel, they flex under stress and shock and can handle oscillating or slow rotational motion.

Quick-Grip Flanged Hydraulic Bushings

Tighten just one set screw to clamp these bushings evenly around your shaft. The screw forces hydraulic fluid in between the double-walled sleeve, expanding the two walls against the shaft and the hub of your sprocket, pulley, or gear for a tight hold. Since you don’t have to tighten multiple screw clamps individually, these bushings are quick to adjust and more likely to stay aligned on your shaft. They’re also good for shock loads. A mounting flange prevents movement during tightening. Use a hex key to tighten.
Note: To avoid deforming the sleeve walls, make sure to fully tighten the screw.
Stainless steel bushings have excellent corrosion resistance in most environments.

Keyless Locking Shaft Couplings for Overhung Loads
![](/prerenderstable/mvPRE/contents/gfx/imagecache/345/3456n11p1-d03c-digitall@halfx_636996537110067868.png?ver=imagenotfound)
Support the weight of a motor and transfer torque to another shaft at the same time with these couplings. Often used to hang motors from conveyor belts and other driven equipment, or to connect long sections of shafts, these couplings eliminate the need for support brackets. Use a torque arm to prevent hanging motors from spinning.
The clamping screws on the coupling face squeeze two outer collars against an inner ring, pressing it tight against shafts to lock them together. This ring-locking mechanism leaves no room for backlash, meaning that all of the turning force created by the motor is passed on to the second shaft. These couplings grip shafts of any shape, so you can install them onto existing keyways and splines without using a key.
To install these couplings, use a torque wrench to tighten each screw to the fastener tightening torque listed for each coupling size. To remove, gradually loosen each screw in sequence until you can slide the coupling on the shaft. Warning: Do not remove any clamping screws from the coupling until the outer collars are separated from the inner ring. The ring is under tension, and a sudden release of the collars can cause serious injury.
Overhung load capacity is the amount of downward force that a coupling can withstand from a motor or other object that it is supporting. To calculate the overhung load, measure the distance from the center of the coupling to the center of gravity of the motor. Multiply that distance by the combined weight of the motor and the portion of the shaft between the coupling and the motor. Do not exceed the overhung load capacity for a coupling.
