Dec 20 2017High-Temp Wheel Bearing Grease For high-temperature components such as wheel bearings a high-temperature silicone-based grease is required These greases are designed to hold stable under high temps and against the elements commonly seen in wheel bearings You can use this grease for chassis components as well but chassis grease is not
Basics of Marine Engineering: BEARING DESIGNATIONS AND
The bearings also have C2 C3 C4 or C5 designation after the bearing number This indicates that the internal fit (the inner race to the ball to outer race) is not standard Always remember that bearings with these designations need to be replaced with the same designators i e a C2 bearing is to be replaced with a C2 bearing only
