Double-Row Ball Bearings | McMaster-Carr

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 appliions. The acetal body doesn’t absorb water, so it can operate in liquids or be washed down without losing strength.
