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.

Electrically Insulated Ball Bearings

Shielded

Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently.

Shielded bearings block out dust and other contaminants.

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.

Angular-Contact Thrust Ball Bearings

Open

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.

Ultra-Thin Ball Bearings

Shielded

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.

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.

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.
