Line 22:

*"Internal clearance”, or fit: Many people get confused when they find out that a bearing can be ordered with different internal clearances (which is the space between the races and the rolling element) and think that one is better than another. A ball bearing is usually supplied with either "normal" or "c3" internal clearance. A ball bearing with "c3" fit simply has more internal clearance (space) than a bearing with "normal" clearance.

:You can use either when replacing a bearing. The main thing to remember is that THE QUALITY IS THE SAME. If given a choice, use the c3 fit; it has more internal clearance to allow for expansion from heat and improper shaft and housing dimensions.

*Ball bearings can be open, or have a seal or shield on one or both sides. The dimensions are the same as an open bearing. If a bearing has a seal/shield on both sides, it does not have to be re-lubricated. The lube that comes from the factory is designed to last for the life of the bearing. This does not mean that a high pressure washer will not blast water in and grease out, so avoid a direct blast from a car wash if you use one.
