AISI440C Stainless Steel bearings are heat treated to a hardness usually from Rockwell C 58 to Rockwell C 61+. All RMB German Product is manufactured to a minimum of Rockwell C 61. The maximum recommended operating temperature is 177o Celsius (350o farenheit).
SAE52100 chrome steel Bearings are usually slightly harder than AISI440C bearings. RMB heat treats their SAE52100 chrome steel bearings to Rockwell C 61-64. The maximum recommended operating temperature of chrome steel bearings is 120o Celsius (248o farenheit).
Operating temperatures higher than those shown above will need special treatment. Please consult SPB.
Bearings for very corrosive environments are made from 316 stainless steel or acetal, but it must be noted that tolerances for these bearings are not as precise as for AISI440C or SAE52100. The available range of these types is limited.
