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.

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing.

Sealed bearings have even better resistance to dust and contaminants than open bearings.

Food Industry Permanently Lubricated Stainless Steel Ball Bearings

Good for applications with incidental food contact, these 440C stainless steel bearings have a food-grade, solid polymer lubricant between the balls and ring that eliminates the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing.

Sealed bearings have even better resistance to dust and contaminants than open bearings.

Ultra-Thin Ball Bearings

Open

Shielded

These bearings have twice as many contact points as angular-contact ball bearings. 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.

Open bearings dissipate heat more efficiently than shielded bearings.

Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Combination Ball/Needle-Roller Bearings

A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle rollers support high radial loads. Install anywhere you would use separate bearings for radial and thrust loads.

Needle-Roller Bearings

Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.

Open bearings dissipate heat more efficiently than sealed bearings.

Sealed bearings block out dust better than open bearings, but retain more heat.

Bearing Retaining Locknuts

Carbon Steel

Stainless Steel

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. 303 stainless steel locknuts resist corrosion better than steel locknuts but aren’t as strong. They withstand washdowns and chemicals.

Bearing Retaining Nuts

Stepped

Chamfered

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle. They have slotted sides, so you can tighten and loosen them with a spanner wrench or spanner socket. Made of carbon steel, they’re strong and wear resistant.

Use stepped-face retaining nuts with DIN 462 spring lock washers. You can also use them in pairs or with other bearing retaining nuts as jam nuts. For the nut closer to the bearing, position the stepped face towards the bearing. All meet DIN standards for bearing lockout dimensions.

Chamfered-face retaining nuts weigh less and produce less heat than stepped-face nuts. They meet ISO 2982 (formerly DIN 981), an international standard for bearing locknut dimensions. Their sizes correspond to SKF KM series. Use them with DIN 5406 spring lock washers.
