- Dip the bearings in oil bath when this is still cold.
Avoid contact between bearings and container.
- Use an appropriate amount of oil (approx.1 l)
- Gradually heat the container with a thermal gun
until the oil temperature reaches approx. 150°.

ded with thermal probe
N.B.
IF THE BEARINGS WERE IMMERSED INTO
HOT OIL, THEY WOULD BE IMMEDIATELY
DAMAGED.
