Auto water pump shaft bearing choose materials

For conventional car water pump shaft bearing choose the material is steel, including the steel roller, outer ring, shaft and other materials are high carbon chromium bearing steel ( GCr15） 。 High quality bearing steel by vacuum deaeration, electromagnetic stirring and oxide content is less. So in can contact under high compressive stress at the same time also can bear larger high tensile stress. Bearing steel after heat treatment, the axis of the raceway hardness of 58 - in general 62HRC。 Ball and roller hardness is 61 - 65 HRC, ring raceway hardness of 60 64HRC。 When even auto water pump shaft bearing outer ring is made of carburizing bearing steel, the hardness of the raceway is 60 64HRC。 A: on the axial clearance of the bearing under a: water pump bearings how maintenance is better?
