Basic Concepts of Metal Ball Bearings

Metal ball bearings are composed of precision-formed, hardened steel or stainless steel balls held together by a metal ring or cage. The balls roll smoothly within the cage, providing a low-friction surface that allows for efficient and precise motion. This design enables smooth rotation under heavy loads and minimizes energy loss due to friction.
