Clevite MS-2022P Engine Crankshaft Main Bearing Set

The Clevite MS-2022P is a high-performance engine crankshaft main bearing set designed for demanding applications. This precision-engineered bearing set features Clevite's proven P-Series design, specifically developed for racing and performance engines where reliability under extreme conditions is critical.

P-Series Performance Design:

• Full groove design maximizes oil flow to connecting rod bearings
• High crush construction ensures maximum bearing retention in the housing
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Hardened steel backing provides added strength and fretting resistance
• High eccentricity design narrows bearing contact patterns for optimal performance

Advanced Bearing Technology:

Clevite's P-Series bearings utilize optimized grooving patterns that balance oil film development with adequate rod bearing lubrication. The 180-degree groove in the upper main shell provides the best overall performance by maintaining oil supply to the connecting rods while preserving the critical oil film on the loaded bearing surfaces. The lower shells remain ungrooved to maximize load-carrying capacity and bearing life.

Ideal Applications:

• Extreme high-RPM racing engines experiencing severe rod bore deformation
• Applications requiring increased oil delivery to rod bearings
• Engines showing signs of rod bearing oil starvation
• Performance builds demanding maximum bearing retention under high loads

This bearing set features Clevite's legendary TriMetal construction, combining a precision steel backing with a high-strength intermediate layer and carefully controlled overlay thickness. The result is a bearing that delivers exceptional durability, embedability, and resistance to fatigue in the most demanding performance applications.
