SKF Bearing Knowledge: Heat bearing mounting - lubsys

Normally a bearing temperature of 80 to 90 (144 to 162 ) above that of the shaft is sufficient for mounting. Never heat a bearing to a temperature greater than 125 (257 ), unless otherwise specified. Extreme heat can cause the material to change metallurgically and produce alterations in diameter or hardness.

Tapered Roller Bearings - BSC

Tapered roller bearings are designed with a cone assely and a cup. The cone assely consists of inner ring, rollers, and cage, while the cup is simply the outer ring. This construction enables tapered roller bearings to support both radial and axial loads, while offering low friction during operation. More rigid bearing appliions can be
