About Ball and Roller 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.
