Clevite MS-2202A Engine Crankshaft Main Bearing Set

The Clevite MS-2202A is a precision-engineered crankshaft main bearing set designed for high-performance and racing applications. This bearing set features advanced TriMetal construction that provides exceptional durability and wear resistance under extreme operating conditions.

Key Features:

• Premium TriMetal construction with optimized overlay thickness to prevent fatigue
• High crush design for maximum retention in the bearing bore
• Engineered grooving pattern to balance oil delivery and film strength
• Enlarged chamfers for improved crankshaft fillet clearance
• No flash plating on steel back for superior seating characteristics
• Hardened steel backing for added strength and fretting resistance

Performance Design:

Clevite main bearing sets utilize a 180-degree groove in the upper shell to optimize oil flow to connecting rod bearings while maintaining maximum oil film thickness in the loaded lower shell. This design provides the best balance between lubrication delivery and bearing load capacity, reducing peak oil film pressure and minimizing horsepower loss compared to fully-grooved designs.

Applications:

Ideal for performance street engines, drag racing, circle track, road racing, and other high-stress applications where bearing reliability is critical. The precision-engineered eccentricity and crush specifications ensure proper contact patterns and oil film development across a wide range of operating conditions.

Clevite bearings are manufactured to exacting tolerances and feature reduced overlay thickness to resist hen tracking and surface fatigue. Each bearing set is designed to work with standard or modified crankshafts and can accommodate the thermal expansion and deflection common in high-output engines.
