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.

Precision Ball Bearings

Shielded

Sealed

For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings.

Shielded bearings dissipate heat more efficiently than sealed bearings.

Sealed bearings block out dust and other contaminants better than shielded bearings.

Self-Aligning Ball Bearings

Open

With a spherical raceway and two rows of balls, these bearings compensate for shaft misalignment.

Open bearings dissipate heat more efficiently than sealed bearings.

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance.

Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Ultra-Thin Ball Bearings

Open

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.

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.

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.
