About Plain Bearings

About Ball and Roller Bearings

About Shaft Collars

Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components. With an open design, they dissipate heat more efficiently than one-piece thrust ball bearings.

Corrosion-Resistant Thrust Ball Bearings

A combination of stainless steel and nylon components provide increased corrosion resistance over standard thrust ball bearings. With an open design, they dissipate heat more efficiently than one-piece thrust ball bearings.

Light Duty Dry-Running Flanged Sleeve Bearings

Use where high loads and speeds are not required.

Thermoplastic-blend bearings have low moisture absorption and create very low friction in applications with light loads, and frequent starts and stops.

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.

Washdown Clamping Shaft Collars

Suitable for use in washdown applications, these plastic collars also offer good chemical resistance. They 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.

Acetal collars have a naturally slippery surface and resist swelling when exposed to moisture.

Quick-Grip Screw-Clamp Bushings

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.

Self-Centering Screw-Clamp Bushings

A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket. They are also good for shock loads. When you tighten the included 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.

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

Split-Tapered Bushings

Steel and Cast Iron

The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered 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.
