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

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.

One-Way Locking Ball Bearing Clutches

Internal locking elements (sprags) lock to transmit torque in one direction while turning freely in the other direction. Use them in applications where precision movement is required, such as pick-and-place and automated indexing conveyor systems. Shields keep out dust and contaminants.
Shielded bearings dissipate heat better than sealed bearings, but don’t keep out as much dust.

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.
Double-row bearings handle thrust loads in both directions.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

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 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.
