Materials and Manufacture of Ball and Roller Bearings

Materials and Manufacture of Ball and Roller Bearings Points : materials and manufacture of ball and roller bearings As the rolling elements and races are subjected to elevated local stresses of unstable magnitude by each revolution of bearing, thus material of rolling element (that is. steel) must be of high quality. Balls are commonly prepared of high carbon chromium steel. Material of equally balls and races are heat treat to provide extra hardness and toughness. Balls are affected through hot forging on hammers as of steel rods. They are then heat treated, ground and polished. The races are too produced through forging and then heat-treated, ground and polished.
