Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

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.

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.

Self-Aligning Flanged Ball Bearings
No need to worry about precisely aligning these bearings—they swivel to compensate for up to 5° of shaft misalignment. The flange ensures proper positioning inside a tube or housing.
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.
