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.

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.
For dirty or dusty environments, sealed bearings are the best choice, since they block out contaminants better than shielded bearings.

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.

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.

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.
Chamfered-face retaining nuts weigh less and produce less heat than stepped-face nuts. Some 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.
Carbon steel retaining nuts are strong and resist wear.
