Clevite MS-2240P High Performance Main Bearing Set

The Clevite MS-2240P is a high-performance P-Series main bearing set engineered for racing and high-RPM applications. This bearing set features full groove design to maximize oil flow to connecting rod bearings, high crush for maximum retention, and reduced overlay thickness to prevent overlay fatigue. Rod bearing oil starvation protection is a key design priority.

Key Features:

• P-Series high performance construction with unique core part numbers
• Full grooved design maximizes oil flow to rod bearings
• High crush design ensures maximum retention in demanding applications
• Reduced overlay thickness prevents overlay fatigue and hen tracking
• Hardened steel back (rod bearings) for added strength and fretting resistance
• High eccentricity design narrows bearing contact patterns and increases rod bearing oiling
• TriMetal bearing construction for strength and durability

Important Notes:

• Use with thrust washer set Part# TW-618S (thrust washers required but not included)
• Ideal for extremely high RPM applications where severe rod bore close-in occurs
• Best suited where increased oiling to rod bearings is needed
• Contact patterns should cover 2/3 to 3/4 of bearing surface for optimal performance

P-Series bearings are Clevite's original high-performance bearing line, offering the greatest amount of eccentricity in rod bearings. These bearings are designed to address rod bearing oil starvation, typically indicated by polishing and smearing of the bearing surface with possible discoloration concentrated at the axial center.
