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.

Electrically Insulated Ball Bearings

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. Shields keep out dust and contaminants.

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.
Open bearings dissipate heat more efficiently than shielded and sealed 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.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Crossed-Roller Bearings

With a considerably larger ID than our Face-Mount Crossed-Roller Bearings, use these to run hydraulic lines, electrical wiring, and other components through the inside of the bearing. 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.
Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

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.
