Clevite MS-2208A Engine Crankshaft Main Bearing Set

The Clevite MS-2208A is a precision-engineered crankshaft main bearing set designed for automotive engines requiring reliable, high-performance lubrication and durability. This bearing set features optimized oil film technology to ensure proper shaft separation and maximum bearing life under demanding operating conditions.

Key Features:

• Tri-Metal bearing construction for superior strength and durability
• Optimized groove design for efficient oil distribution to connecting rods
• 180-degree upper shell grooving provides ideal balance of oil flow and film strength
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• High crush design ensures maximum retention in the engine block
• Precision-manufactured to OEM specifications for proper fitment

Engineering Design:

This main bearing set utilizes advanced bearing grooving technology to optimize oil film performance. The upper main shells feature a 180-degree groove that effectively supplies oil to the connecting rod bearings while maintaining maximum oil film thickness in critical load areas. The lower main shells are designed without grooving to develop a thicker oil film, providing greater safety margins and improved bearing longevity compared to older full-grooved designs.

Performance Series Options:

Clevite offers multiple bearing series to match specific engine requirements and operating conditions. The P-Series bearings feature maximum eccentricity and full grooving for high-RPM applications with extreme rod bore close-in. H-Series bearings provide medium eccentricity with enlarged chamfers for oversize crankshaft fillets, making them ideal for medium to high RPM racing applications. K-Series bearings incorporate proprietary moly/graphite TriArmor coating for enhanced wear protection. V-Series bearings utilize lead-indium overlay for superior conformability, while M-Series micro bearings offer exceptional conformability for engines experiencing severe crankshaft deflection.

This bearing set delivers the precision fit, durability, and lubrication performance required for both stock rebuilds and performance applications.
