Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

With twice as many contact points as angular-contact ball bearings, these bearings resist any combination of radial, thrust, and moment (twisting) loads. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.

A reliable classic—these babbitt bearings are strong and corrosion resistant.

Bearings with split housing have a removable section for easy maintenance.

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.

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 style. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

Engineered for simultaneous linear and rotary motion, these bearings are used with round end-supported shafts. The fixed-alignment design is for use where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).

Tighten the set screw to bite into an unhardened shaft for a secure hold. The two-piece design allows you to install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Clamping screws provide extra grip.

Carbon steel collars are strong and wear resistant. Their black-oxide finish is somewhat corrosion resistant, but only in dry environments. Their dark color can be useful for matching other parts in your system.

303 stainless steel collars are corrosion resistant and highly machinable.

Three tapped counterbored holes and three unthreaded holes provide mounting flexibility. Collars clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screws to secure.

Collars with keyway have a standard ANSI keyway for use with keyed shafts, keys, and key stock.

Black-oxide steel collars are stronger than aluminum and stainless steel collars. They have some corrosion resistance. Aluminum collars are lightweight and have good corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

Two tapped holes on the face of these collars allow you to fasten them to gears, pulleys, and sprockets. Collars clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screw to secure.

These couplings have the gripping strength to handle higher torque than most other couplings. Couplings clamp evenly around the shaft to create a mar-free hold. Slide onto the end of your shaft and tighten the clamping screws to secure. Good for high-torque applications, rigid couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.

When your shafts are not close enough to use standard couplings, these have the length to bridge the gap. Install them anywhere on a shaft without removing components or having access to the ends of the shaft. Tighten the clamping screws to secure.

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.
