Clevite MS-2220H High Performance Engine Main Bearing Set H-Series

The Clevite MS-2220H is a high-performance engine crankshaft main bearing set from the H-Series line, engineered specifically for competitive racing applications including NASCAR and other motorsports. These bearings feature advanced TriMetal construction designed to withstand the demanding conditions of high-RPM performance engines.

H-Series Performance Features:

• Medium eccentricity design for optimal load distribution and bearing contact patterns
• High crush specification 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 accommodate crankshafts with oversize fillets
• Non-flash plated for improved bearing seating and performance
• Standard 180-degree upper half grooving optimizes oil film thickness

Advanced Bearing Technology:

H-Series bearings utilize engineered grooving patterns that balance connecting rod lubrication with maximum oil film development. The 180-degree groove in the upper main shell efficiently supplies oil to connecting rod bearings while the ungrooved lower shell maintains the thickest possible oil film for superior load-carrying capacity and extended bearing life.

Application Guidelines:

H-Series bearings are the recommended starting point for most performance engine builds operating in medium to high RPM ranges. They work exceptionally well with crankshafts featuring oversize fillets and provide ideal contact patterns covering approximately 2/3 to 3/4 of the bearing surface. These bearings offer the perfect balance between the high eccentricity of P-Series and low eccentricity of V-Series bearings.

Clevite's legendary TriMetal bearing construction combines a precision-engineered copper-lead lining with lead-tin-copper overlay, delivering exceptional strength, durability, and wear resistance for competitive racing applications.
