Clevite MS-2200P-20 High Performance Main Bearing Set P-Series

The Clevite MS-2200P-20 is a high-performance P-Series main bearing set designed for demanding racing and performance engine applications. This bearing set features advanced engineering to maximize oil delivery to connecting rod bearings while maintaining optimal shaft support and load capacity.

P-Series Performance Design:

• Full groove design maximizes oil flow to rod bearings for improved lubrication
• High eccentricity construction narrows bearing contact patterns for concentrated load distribution
• High crush design ensures maximum retention in the bearing bore
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Hardened steel backing provides added strength and resistance to fretting
• TriMetal construction delivers legendary Clevite durability

Engineered Oil Film Technology:

This bearing set utilizes optimized 180-degree grooving in the upper main shell, which research has proven provides the best overall performance for high-output engines. The upper shell's groove efficiently supplies oil to connecting rods, while the ungrooved lower shell maintains a thicker oil film for superior load-carrying capacity and extended bearing life under high-stress conditions.

Ideal Applications:

Use P-Series main bearings when extremely high RPM operation causes severe rod bore close-in, or when rod bearing oil starvation is indicated by surface polishing, smearing, or discoloration concentrated at the bearing's axial center. These bearings are specifically engineered for competition engines requiring maximum oil delivery to prevent rod bearing failure.

Each main bearing features precise manufacturing tolerances and is designed without flash plating for improved seating characteristics. The P-Series represents Clevite's original high-performance bearing design, proven in countless racing applications across multiple motorsports disciplines.
