Clevite MS-2199H-10 High Performance Crankshaft Main Bearing Set

The Clevite MS-2199H-10 is a high-performance crankshaft main bearing set designed for demanding racing and performance engine applications. This H-Series bearing set features advanced engineering specifically developed for NASCAR-type racing and competition engines operating in medium to high RPM ranges.

H-Series Performance Features:

• Medium level of eccentricity for optimal load distribution and contact patterns
• High crush design for maximum bearing retention under extreme conditions
• Hardened steel backing for superior strength and resistance to fretting
• Thin overlay construction to prevent overlay fatigue (hen tracking)
• Enlarged chamfers providing greater crankshaft fillet clearance
• No flash plating for improved bearing seating and conformability
• Standard 180-degree upper shell grooving for optimal oil distribution

Why H-Series Design Matters:

The H-Series bears Clevite's legendary TriMetal construction with design parameters optimized for high-performance applications. The 180-degree groove in the upper main shell provides the best overall performance by supplying adequate oil to connecting rod bearings while maintaining maximum oil film thickness in the loaded lower bearing area. This design delivers superior bearing life and protection compared to full-grooved alternatives.

Ideal Applications:

Choose H-Series bearings when working with crankshafts that have oversized fillets or when you need contact patterns covering 2/3 to 3/4 of the bearing surface. These bearings are the recommended starting point for most performance engine builds where you need a balance of durability, oil flow, and load-carrying capacity. If P-Series bearings produce contact patterns that are too narrow, H-Series bearings provide the solution.

Clevite engine bearings are trusted by professional engine builders and racers worldwide for their consistent quality, precise manufacturing tolerances, and proven performance under the most demanding conditions.
