Clevite MS-1432H-10 Engine Crankshaft Main Bearing Set

The Clevite MS-1432H-10 is a high-performance engine crankshaft main bearing set designed for demanding racing and competition applications. This H-Series bearing set features advanced engineering specifically developed for NASCAR-type racing and other high-performance engines operating in medium to high RPM ranges.

H-Series Performance Features:

• Medium level of eccentricity for optimal load distribution and bearing contact patterns
• High crush design ensures maximum bearing retention under extreme conditions
• Hardened steel backing provides superior strength and resistance to fretting
• Thin overlay construction prevents overlay fatigue and "hen tracking"
• Enlarged chamfers deliver greater crankshaft fillet clearance for oversize fillet crankshafts
• Non-flash plated for improved bearing seating and retention
• Standard 180-degree upper half grooving optimizes oil film thickness while supplying connecting rod bearings

Advanced Bearing Technology:

Clevite's H-Series bearings utilize proven TriMetal construction with a carefully engineered groove design. The 180-degree groove in the upper main shell provides the optimal balance between oil delivery to connecting rods and maintaining maximum oil film thickness for shaft protection. This design prevents the performance losses associated with extended grooving while ensuring adequate lubrication throughout the engine.

Application Guidelines:

H-Series bearings are the recommended starting point for most performance engine builds. Use these bearings when working with crankshafts featuring oversize fillets, or when P-Series bearings produce contact patterns that are too narrow. Ideal bearing contact should cover approximately 2/3 to 3/4 of the bearing surface for optimal performance and longevity.

The MS-1432H-10 set delivers the reliability and performance characteristics demanded by professional engine builders and serious racers who require consistent, predictable bearing performance under the most challenging operating conditions.
