Clevite MS-2022P-30 P-Series Performance Main Bearing Set

The Clevite MS-2022P-30 is a high-performance main bearing set designed for racing and performance applications. This P-Series bearing features full groove design to maximize oil flow to connecting rod bearings, making it ideal for engines experiencing oil starvation issues at the rod bearings.

Key Features:

• P-Series design with maximum eccentricity for severe rod bore close-in conditions
• Full grooved upper shells for enhanced oil delivery to connecting rods
• High crush design ensures maximum bearing retention
• Reduced overlay thickness prevents overlay fatigue and hen tracking
• Hardened steel backing for added strength and fretting resistance
• TriMetal construction for superior strength and durability
• No flash plating for improved bearing seating

Application Guidelines:

P-Series main bearings are recommended when higher bearing eccentricity is needed to narrow contact patterns and increase oil flow to rod bearings. These bearings excel in high-RPM applications where rod bearing oil starvation is indicated by surface polishing, smearing, or discoloration concentrated at the bearing's axial center. The full groove design provides critical lubrication pathways that help prevent rod bearing failure in demanding performance conditions.

These bearings utilize Clevite's proven TriMetal construction with lead-tin-copper overlay, combining exceptional load-carrying capacity with excellent conformability. The hardened steel back provides structural rigidity while the precision-engineered bearing surface maintains the critical oil film necessary for reliable operation under extreme loads.
