Shaft bearing material selection

Axis material selection of the bearing axis bearing is even a simplified double support bearing structure, two supporting bearings without inner ring, rolling body race done directly on the shaft, two supporting bearing outer ring to make a whole, two with packing seal ring, shaft sleeve assembly. Even regular shaft bearing steel ( Including shaft, outer ring, roller ball) For the high carbon chromium bearing steel ( GCr15） 。 Because of the high quality of bearing steel smelting by vacuum deaeration, electromagnetic stirring, oxide content is less, in can contact under high compressive stress at the same time also can bear larger high tensile stress, after heat treatment, raceway hardness of 58 - axis 62HRC。 In the ring raceway hardness of 60 64 HRC, ball and roller hardness is 61 - 65HRC。 When the shaft, the outer ring is made of carburizing bearing steel, roll hardness of 60 64HRC。 Maintains a material usually choose reinforced nylon 66, materials commonly used nitrile butadiene rubber sealing ring, when the demand is higher, also can choose fluorine rubber seal.
