Permanently Lubricated Stainless Steel Ball Bearings
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.

Ultra-Thin Ball Bearings
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.

High-Load Crossed-Roller Bearings
The thicker inner and outer raceways on these bearings can handle heavier loads than the thin-profile crossed-roller bearings. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.
Open bearings dissipate heat more efficiently than sealed bearings.
Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

Multipurpose Sleeve Bearings
These 932 bearing bronze bearings are strong, wear resistant, and excellent at handling shock loads. They’re sometimes called 660 leaded bronze bearings.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Multipurpose Sleeve Bearings with Groove
A figure-8-shaped groove provides a flow path for lubricant, distributing it evenly along the bearing’s surface. Bearings are cast bronze, making them strong, wear resistant, and excellent at handling shock loads. 932 bearing bronze is sometimes called 660 leaded bronze.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.
