Clevite MS-2202A-.50MM Engine Crankshaft Main Bearing Set .50mm Undersize

The Clevite MS-2202A-.50MM is a precision-engineered crankshaft main bearing set designed for .50mm undersize applications. This complete main bearing set provides the critical interface between your engine's crankshaft and block, maintaining proper oil film thickness and load distribution under demanding operating conditions.

Key Features:

• .50mm undersize for reground crankshafts
• TriMetal construction with copper-lead lining and lead-tin-copper overlay
• Optimized 180-degree upper shell grooving for maximum oil film strength
• High crush design for superior bearing retention
• Reduced overlay thickness prevents overlay fatigue and hen tracking
• Hardened steel backing for added strength and durability

Engineering Design:

Clevite main bearings utilize proven 180-degree upper shell grooving that provides optimal oil delivery to connecting rod bearings while maintaining maximum oil film thickness in loaded bearing areas. The ungrooved lower shells ensure the thickest possible oil film where loads are highest, providing superior protection and extended bearing life compared to fully-grooved designs.

Application Notes:

This bearing set is engineered for engines with reground crankshafts requiring .50mm undersize bearings. The TriMetal construction offers excellent load capacity, conformability, and wear resistance for both street and performance applications. Proper installation requires thorough cleaning of all bearing surfaces and verification of proper oil clearances before assembly.
