Ball Bearings
Open bearings dissipate heat more efficiently than shielded and sealed bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Permanently Lubricated Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the 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.

Angular-Contact Thrust Ball Bearings
Install these bearings for use with combined radial and thrust loads. They are often used in spindle applications and can be combined with cylindrical roller bearings to better handle radial loads.
Single-row bearings handle thrust loads on one side. For applications with thrust loads on both sides, mount them in pairs.
Open bearings dissipate heat more efficiently than shielded and sealed bearings.

Spherical-Roller Bearings
Two rows of rollers give these bearings dynamic radial load capacities over five times higher than comparably sized tapered-roller bearings. Also known as rock crusher bearings, they handle heavy shock loads and are used for metal milling machinery, mining and oil field equipment, and in paper mills.
For technical drawings and 3-D models, click on a part number.
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 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. Zinc-plated steel locknuts resist rusting from some moisture, but you shouldn’t use them with salt water or chemicals.

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.
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.

Bearing Retaining Jam Nuts
Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle. Threading two nuts tightly against each other makes it harder for vibration to loosen your assembly than if you used only one nut. For the nut closer to the bearing, position the stepped face towards the bearing. These jam nuts have holes on the side, so you can tighten and loosen them with a pin spanner wrench. Made of carbon steel, they’re strong and wear resistant. All meet DIN 1816, an international standard for bearing locknut dimensions.
