Clevite MS-2200P Engine Crankshaft Main Bearing Set

The Clevite MS-2200P is a high-performance crankshaft main bearing set designed for demanding engine applications. This P-Series bearing set features specialized engineering to optimize oil film strength and bearing life in performance and racing engines.

P-Series Performance Features:

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

Advanced Bearing Design:

Clevite's engineering research confirms that proper main bearing groove design is critical for performance. This P-Series set utilizes a 180-degree groove in the upper shell, which provides optimal oil distribution to the connecting rods while maintaining maximum oil film thickness in the loaded lower shell. The upper shells handle lower loads and feed oil to the rods, while the ungrooved lower shells develop a thicker oil film for superior load capacity and extended bearing life.

Applications:

P-Series main bearings are ideal for engines experiencing rod bearing oil starvation, indicated by surface polishing, smearing, or discoloration concentrated at the bearing's axial center. These bearings excel in applications requiring maximum oil delivery to rod bearings and where higher eccentricity is needed to optimize contact patterns. They're particularly effective in extreme RPM conditions where conventional bearings show excessive bore close-in.

This main bearing set represents decades of bearing technology refinement, combining high crush retention, optimized groove geometry, and proven TriMetal construction for reliable performance in street performance and competition engines.
