Cautions for handling • Store condition • Clean • Non-Humid • Place which is not exposed to direct sunshine • Air flow between the box and floor
No Good !! Danger Dusty Humidity Untidy Sunshine
Fitting a Bearing on the Shaft Always press the ring to be fitted.
Fitting a Bearing into a Housing Always press on the ring to be fitted.
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 Without using flames or oil uniform heating in short time is possible, making shrink fitting efficient and clean. • Precautions • Make Sure Oil Is Free of Sludge • Control Temperature, Do Not Overheat • Keep Tank Covered When Not In
Bearing Removal Procedures • Mark position/orientation of bearing • Remove very carefully to avoid damage to shaft/housing • Use appropriate tools (not hammers) • Apply pressure to the ring with the interference fit
Misalignment Misalignment due to the bearing being mounted out of square.
