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.

Precision Angular-Contact Thrust Ball Bearings
These bearings have angular raceways for combined thrust and radial loads—install them where precision tolerances are required for accuracy and high speeds. They’re often used in spindle applications. To handle thrust loads in both directions, they have a double-row construction. Pair them with cylindrical roller bearings to better handle radial loads. They have an open construction to dissipate heat efficiently.

Needle-Roller Thrust Bearings
Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings. Because of the large contact area between the rollers and washers (not included), these bearings are great for medium to heavy duty, low-friction jobs. For use on hardened and ground surfaces.
Washers allow you to use the bearing on unhardened and unground surfaces.

Bearing Retaining Locknuts
With a nylon insert that grips your threaded shaft or spindle without damaging the threads, these locknuts—sometimes called shaft nuts—keep bearings, bushings, gears, and pulleys in place. They won’t shake loose from vibration. However, their nylon insert also means you shouldn’t use these locknuts in applications with high temperatures. Their sides are slotted, so you can tighten and loosen them with a spanner wrench or spanner socket. To reduce the total size and weight of your assembly, they have chamfered edges.
All meet international standards for bearing locknut dimensions.
Carbon steel locknuts are strong and wear resistant. When choosing your thread spacing, consider the precision of your application. The finer the threads, the more control you have when making adjustments.

Bearing Retaining Nuts
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.
