Clevite MS-2199H-1 High Performance Engine Crankshaft Main Bearing Set

The Clevite MS-2199H-1 is a high-performance main bearing set engineered for demanding racing and performance applications. Part of Clevite's renowned H-Series line, this bearing set delivers the durability and precision required for competition engines operating in medium to high RPM ranges.

H-Series Design Features:

• Medium eccentricity profile optimized for performance applications
• High crush design ensures maximum bearing retention under extreme loads
• Hardened steel backing provides exceptional strength and fretting resistance
• Thin overlay construction prevents overlay fatigue and "hen tracking"
• Enlarged chamfers accommodate crankshafts with oversized fillets
• Non-flash plated for superior seating and contact
• Standard 180-degree upper shell grooving for optimal oil delivery

Advanced Bearing Technology:

This bearing set utilizes Clevite's proven TriMetal construction, which creates a critical oil film that separates the bearing from the shaft surface during rotation. The 180-degree groove design in the upper main shell provides essential oil supply to connecting rod bearings while maintaining maximum oil film thickness in high-load areas. The ungrooved lower shells deliver superior performance by maintaining a thicker oil film for increased safety margin and extended bearing life.

Applications:

Originally developed for NASCAR racing applications, H-Series bearings are suitable for all competition engines requiring crankshafts with oversize fillets. The medium eccentricity design produces ideal contact patterns covering 2/3 to 3/4 of the bearing surface, making H-Series the recommended starting point for most high-performance builds. These bearings excel in applications where P-Series contact patterns prove too narrow or where consistent performance across varying RPM ranges is critical.

Professional Grade Quality:

Clevite H-Series bearings represent decades of bearing technology development and real-world racing validation. The combination of high crush, hardened steel backing, and optimized eccentricity makes this bearing set an excellent choice for engine builders who demand reliability under the most punishing conditions.
