Clevite MS-2056A-.75MM High Performance Engine Main Bearing Set

The Clevite MS-2056A-.75MM is a high-performance engine crankshaft main bearing set designed for demanding applications. This bearing set features precision-engineered TriMetal construction that provides exceptional strength and durability for both competition and high-performance street engines.

Key Features:

• TriMetal bearing construction with superior strength and wear resistance
• Optimized 180-degree upper shell grooving for maximum oil film thickness
• High crush design for maximum bearing retention
• Reduced overlay thickness to prevent overlay fatigue
• Available in .75mm undersize for reground crankshafts
• Engineered without flash plating for improved seating characteristics

Advanced Bearing Technology:

Clevite main bearings utilize advanced grooving technology based on extensive performance testing. The upper main shells feature a 180-degree groove that provides optimal oil delivery to connecting rod bearings while maintaining maximum oil film thickness in critical load zones. The lower main shells are ungrooved, allowing the crankshaft to develop a thicker oil film for improved bearing life and greater safety margins under high-load conditions.

Performance Series Options:

Clevite offers multiple bearing series to match specific engine requirements. P-Series bearings provide maximum eccentricity and oil flow with full grooving, ideal for applications experiencing rod bearing oil starvation. H-Series bearings feature medium eccentricity with enlarged chamfers for increased fillet clearance, making them suitable for most performance applications. K-Series bearings incorporate proprietary moly/graphite TriArmor coating for enhanced protection during start-up and high-load conditions. V-Series bearings utilize lead-indium overlay for superior conformability. M-Series micro bearings feature .006-inch thick babbitt lining for extreme conformability in engines with severe crankshaft deflection.

This bearing set is engineered for engines operating in medium to high RPM ranges where reliability and performance are critical. Proper bearing selection and clearance checking are essential for optimal performance and longevity.
