Temperature limit
The permissible operating temperature of self-aligning ball bearings is limited to:
Dimensional stability of bearing ring and steel ball
cage
The seals
lubricant
When the expected temperature exceeds the allowable range, contact the DSR bearing
Bearing ring and steel ball
Self-aligning ball bearings have thermal stability up to 120 °C (250 °F).
cage
The working temperature of the steel or brass cage is the same as that of the bearing ring and ball.For temperature limits for polymer retainers, see Polymer retainers.
The seals
The allowable operating temperature of NBR seals is -40 to +100 °C (-40 to +210 °F).It can withstand temperatures up to 120 °C (250 °F) in a short time.
Usually, the peak temperature is located in the sealing lip.
lubricant
The diagram lists the temperature limits of greases used in SKF sealed self-aligning ball bearings.
