600 Pcs Precision Ball Bearings, Stainless Steel Bearings Balls Set, 13 Sizes Bicycle Bearing Steel Ball Assortment Kit for Bicycles, Skateboard, Motorcycles, Casters

•Exquisite Material: All bearing balls are made of high-quality stainless steel with smooth polished surface, corrosion resistance, rust resistance, strong toughness, strong oxidation resistance, and can maintain high performance in harsh environments, and durable.

•Function of Steel Ball Bearings: A ball bearing is a rolling bearing used to carry loads, reduce friction and position movement. Ball bearings use stainless steel ball bearings to reduce surface contact and friction between moving planes.

•Easy to Use: The purpose of a stainless steel ball bearing is to reduce rotational friction and support radial and axial loads, used to installed between the inner and outer rings, which can be used to reduce the friction when the bearings rotate, thus reducing the speed of the ball bearings and extending the life of the machine.

•Wide Range of Applications: The stainless steel balls set is an ideal tool for bicycles to replace front and rear wheel bearings and bottom brackets, keeping the pedaling process smooth and efficient. Widely used in bicycles, motorcycles, auto parts, bearings, casters, drawer slides, door locks, home furniture, aerospace, instrumentation, and many other applications.
