Permitted working temperature of deep groove ball bearing depend on：
Dimension stability of bearing ring and steel ball
Material of cage
Material of sealing
When the temperature exceed the working temperature range, please contact with LYC project service department.
Bearing ring and steel ball
Normal deep groove ball bearing can working stably under the temperature of 120°C (250°F).
The temperature of steel，brass is the same as bearing ring and steel ball. Temperature limiting value of other polymer material cage， please refer to cage material.
Sealing part permitted working temperature depends on material：
NBR sealing part：from -40 to +100 °C，even can bear 120 °C in short times.
FKM sealing ring：from-30 to +230 °C(-20 to +445 °F)
