Fitting a Bearing on the Shaft
Thermal Mounting
  • Use oven, hot plate, or NSK bearing induction heater
  • Clean heating apparatus
  • Exercise care when using hot oil bath
  • Do not heat above 248 deg F (120 deg C)
  • Reference inner ring expansion chart in NSK catalog, fig. 14.3

Under no circumstances should you heat a bearing by directly putting the torch on the bearing surface.

  • Advantages
    • Heat Large Heats Efficiently
    • Safe For Bearing
  • Disadvantages
    • Oil Can Contaminate Bearing
    • Heating Oil May Not Compatible with Lube
    • Can Not Heat Sealed Bearings By This Method
  • Precautions
    • Make Sure Oil Is Free of Sludge
    • Control Temperature, Do Not Overheat
    • Keep Tank Covered When Not In

Without using flames or oil uniform heating in short time is possible, making shrink fitting efficient and clean.
