Bearings are a wear item and should never be re-used. If you are building an engine, put a good of bearings in it. We use Clevite often and they never give us problems. These are STD size bearings. If you need help with bearing size, please contact us now to help you get the right parts the first time, and get your engine back up and running as quickly as possible.
P-Series main bearings are the oldest members of the Clevite 77 bearing family and are intended for high-revving engines. To compensate for the high-load factors and distortion in these engines, these bearings have higher eccentricity and a high crush factor. P-Series bearings are built on steel backings with extra-thin overlays to prevent overlay fatigue. In addition, the oil grooves on most applications extend all the way around both halves for better oiling.
