For much of the history of manufacturing, steel has been the material of choice for manufacturing ball bearings. Modern steel bearings are typically made from either 52100 steel or 440C stainless steel. However, steel has one major weakness: it rusts. This makes steel a poor choice for any application that involves large amounts of water, such as food processing, swimming pools, boating, and medical applications. Plastic bearings, on the other hand, are easily machined or molded for such purposes, and have several advantages over conventional steel. In this blog, we will list several of those advantages.
