Set Screw Collar Ball Bearings
Slip these bearings onto a shaft and secure with the included set screws, no special tools required. All have an extended inner ring for additional shaft support.
Bearings with a black-oxide steel ring have some corrosion resistance.
Shielded bearings dissipate heat more efficiently than sealed bearings.
Sealed bearings block out dust and other contaminants better than shielded bearings.
Bearings with a retaining ring have a removable retaining ring that holds the bearing inside a housing.

Clamp-On Collar Ball Bearings
Quickly secure these bearings onto shafts with the clamp-on collar for a concentric, mar-free hold. Tighten the single screw on the locking collar around its inner ring on your shaft to center and secure the shaft in the bearing bore. The collar’s firm grip reduces vibration and noise in your system. The steel rings on these bearings have a black-oxide finish for some corrosion resistance.

Washdown Set Screw Collar Ball Bearings
Secure these bearings in washdown areas, such as food, beverage, pharmaceutical, and chemical plants, by tightening the set screw onto a shaft—no additional collar needed. Similar to 304 stainless steel, the nickel-coated steel rings on these bearings won’t break down from water. The extended inner ring increases shaft support. All of these bearings have NSF registered H1 lubrication, which is certified for incidental contact with food.

Washdown Clamp-On Collar Ball Bearings
Designed to stand up to frequent washdowns, you can quickly secure these ball bearings onto shafts with the clamp-on collar in food, beverage, pharmaceutical, and chemical plants. The collar centers your shafts and secures them better than set screw ball bearings, which reduces vibration and noise. To install these bearings, tighten the single screw on the collar around its inner ring on your shaft for a mar-free hold.
Coated with nickel, the steel rings on these bearings won’t corrode from water and harsh cleaners, similar to 304 stainless steel. The inner ring is extended for added shaft support. All of these bearings have NSF registered H1 lubrication, which is certified for incidental contact with food and is suitable for food and beverage applications.

High-Load Mounted Linear Ball Bearings for Support Rail Shafts
Designed to handle heavy loads, these bearings have higher load capacities than comparable standard mounted linear ball bearings for support rails. Use them for applications that require maximum rigidity. All are self-aligning to compensate for shaft misalignment and have end seals to keep lubricant in and dirt out.

Bearing Retaining Locknuts
With a nylon insert that grips your threaded shaft or spindle without damaging its threads, these locknuts—also called shaft nuts—hold bearings, bushings, gears, and pulleys prone to vibration tightly in place. They come as one piece, so you can easily clamp them onto your shaft or spindle. But, since they aren’t made entirely of metal, they don’t stand up to heat as well as all-metal locknuts. Slots in their sides mean you can tighten and loosen them with a spanner wrench or spanner socket. Their face is also chamfered to help keep the size and weight of your assembly at a minimum. All meet international standards for bearing locknut dimensions.
When choosing your thread spacing, consider the precision of your application. The finer the threads, the more control you have when making adjustments.
All carbon steel locknuts are strong and resist wear, though they don’t stand up to corrosion as well as stainless steel locknuts.

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.
