How to properly mount bearings | PI Process InstrumentationOct 15, 2014 — Normally, a bearing temperature of 150 F (83 C) above that of the shaft is sufficient. Unless otherwise specified, open bearings should never be heated to a temperature greater than 257 F (125 C). Extreme heat can cause the bearing's metallurgy to change, which can alter bearing dimensions and/or hardnessHow do you avoid damage when heating a bearing whileApr 8, 2019 — In addition, the temperature must be high enough (maximum of 130°C for a bearing) to generate sufficient expansion and temporarily loosen the
