    Dry-Running Ball Bearings

    Image of Product. Front orientation. Ball Bearings. Dry-Running Ball Bearings.
    Made of naturally slippery plastic so there's no lubricant to maintain or make a mess. These bearings are ideal for spic-and-span spaces since oil won't drip off, wash out, or collect dust over time. They won't rust or warp from moisture, so they stand up to thorough cleanings.
    Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, reducing wear and extending the life of the bearing.
    Acetal—The most common choice for plastic bearings, acetal is economical yet still stands up to daily wear and tear.
    Chemical-Resistant PVDF—A step up from acetal, PVDF won't corrode when exposed to most strong acids and solvents.
    High-Temperature Chemical-Resistant PEEK—The most heat- and chemical-resistant plastic bearings we offer. Even inside autoclaves as hot as 330° F, PEEK won't melt. It also won't degrade when exposed to harsh acids and bases.
    316 Stainless Steel Balls—Won't corrode from salt water or harsh chemicals, such as bleach and chlorine found in cleaning solutions.
    Glass Balls—Nonmagnetic, so they won't interfere with sensors and other sensitive electronics.

    Ball Bearings

    Smoother than smooth—the balls inside these bearings roll nearly friction-free. You’ll often find them on rapidly rotating parts, from the whirring chuck on a power drill to the spinning shaft on an electric motor.
    Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.
    Highly Corrosion-Resistant 316 Stainless Steel—The most corrosion-resistant metal bearings we offer. They won't pit or weaken from salt water or harsh chemicals, such as bleach and chlorine found in cleaning solutions.
