CHROME & STAINLESS STEEL STEEL BALL MATERIAL For years, the ball bearing has helped maintain smooth, flawless machine operations. The lowly steel ball and bearing were critical to creating the Industrial Revolution, just as they are essential components in today’s endless variety of manufacturing, recreational and high-technology equipment. 52100 Chrome Steel: Contains chromium and, due to through hardening, has excellent surface quality and high load capability. A universal material for many applications. 440C Stainless Steel: A martenistictype stainless steel used extensively in bearing...
