Precision Ball Bearings
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.

High-Load Plastic Ball Bearings
With two rows of balls, these lightweight bearings have greater durability and load capacity—and a wider profile—than single-row plastic bearings. They’re commonly used in bottle-filling machines and other food-processing applications. The acetal body doesn’t absorb water, so it can operate in liquids or be washed down without losing strength. The balls are made of either glass or 316 stainless steel—both materials are corrosion resistant. Since there’s no metal-on-metal contact between the balls and the body, these bearings don’t require lubrication.

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.
