Clevite MS1566P P-Series Main Bearing Set

The Clevite MS1566P is a P-Series main bearing set designed for high-performance and heavy-duty engine applications. Part of the legendary Clevite 77 bearing family, P-Series bearings have been trusted by engine builders since they were first introduced as Clevite's original performance bearing line.

Tri-Metal Construction:

• Precision steel backing for maximum strength and support
• Cast copper-lead intermediate layer provides superior load-carrying capacity
• Electroplated babbitt overlay on running surface delivers excellent conformability and embedability
• High crush factor ensures proper retention and seating in the bearing bore

Performance Features:

• Higher eccentricity design compensates for high-load factors and bore distortion in demanding applications
• Optimized for high-revving engines and heavy-duty use
• Superior fatigue resistance compared to standard bimetal bearings
• Enhanced heat transfer properties through improved crush characteristics

Clevite P-Series main bearings are ideal for rebuilding engines where more demanding use is anticipated, including motorsports, street performance, heavy-duty commercial, and marine applications. The tri-metal construction provides the best overall combination of conformability, embedability, and fatigue resistance.
