Clevite MS1621P10 P-Series Main Bearing Set

The Clevite MS1621P10 is a P-Series main bearing set designed for high-revving performance engines. Part of the Clevite 77 bearing family, this set delivers professional-grade durability and precision for demanding engine applications.

Construction and Materials:

• Tri-metal cast copper lead construction for superior strength
• Hardened steel backing for structural support
• Cast copper lead lining to withstand heavy operational loads
• Electroplated babbitt overlay on running surface for optimal bearing characteristics

Performance Features:

• Higher eccentricity design compensates for high-load factors and engine distortion
• High crush factor ensures proper bearing retention
• Oil grooves extend around both halves for enhanced lubrication
• Engineered for conformability, embedability, and fatigue resistance

P-Series bearings are ideal for high-performance and competition engines where reliability under extreme conditions is critical. The tri-metal design provides superior performance compared to standard bimetal bearings, making them a trusted choice for engine builders and enthusiasts.
