Clevite MS-2199A-10 Performance Engine Crankshaft Main Bearing Set

The Clevite MS-2199A-10 is a high-performance engine crankshaft main bearing set engineered for demanding applications. This main bearing set features Clevite's proven tri-metal construction, combining a steel backing with a performance-optimized overlay designed to maintain proper oil film thickness under high loads and temperatures.

Key Features:

• Tri-metal construction with steel backing for maximum strength and durability
• Optimized bearing grooving design for superior oil film development and rod bearing lubrication
• High crush design ensures positive retention in the main bearing saddles
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Precision-manufactured to exacting tolerances for consistent performance
• Designed for both street performance and racing applications

Engineering Design:

This bearing set utilizes a 180-degree groove in the upper main shell, which provides optimal oil distribution to connecting rod bearings while maintaining maximum oil film thickness in the loaded lower bearing shell. This design delivers the best balance between adequate rod bearing lubrication and main bearing protection, reducing peak oil film pressure and minimizing parasitic horsepower loss.

Applications:

Ideal for rebuilt engines, performance builds, and racing applications where reliable main bearing performance is critical. The MS-2199A-10 provides the durability needed for high-RPM operation while maintaining the oil film characteristics necessary for long bearing life.
