Clevite MS-1010H-10 High Performance Crankshaft Main Bearing Set

The Clevite MS-1010H-10 is a high-performance 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 eccentricity design for optimal load distribution and bearing contact patterns
• High crush construction ensures maximum bearing retention under extreme conditions
• Hardened steel back with thin overlay for enhanced strength and durability
• Enlarged chamfers provide superior crankshaft fillet clearance
• Non-flash plated finish promotes better bearing seating and bedding
• Standard 180-degree upper half grooving maximizes oil film thickness while supplying adequate oil to connecting rod bearings

Advanced Bearing Design:

This bearing set utilizes Clevite's legendary TriMetal construction, which creates an oil film through shaft rotation that keeps bearings separated from the crankshaft surface. The 180-degree groove design in the upper shell provides the optimal balance between oil delivery to rod bearings and maintaining maximum oil film pressure on the loaded lower bearing surface. Unlike older full-grooved designs, this configuration delivers superior bearing life and performance.

Ideal Applications:

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