Clevite MS-2022A Engine Crankshaft Main Bearing Set

The Clevite MS-2022A is a precision-engineered crankshaft main bearing set designed for performance and racing applications. This set features Clevite's proven tri-metal construction, combining a steel backing with a high-strength copper-lead intermediate layer and a lead-tin-copper overlay for exceptional durability and load-carrying capacity.

Key Features:

• Tri-metal construction with hardened steel backing for maximum strength
• Optimized bearing groove design for superior oil film retention
• High crush design ensures positive retention in the housing
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Enlarged chamfers provide clearance for oversize crankshaft fillets
• No flash plating for improved seating characteristics
• Engineered for high-RPM performance and racing applications

Technical Design:

This bearing set utilizes an optimized 180-degree groove in the upper main shell, which provides the ideal balance between oil delivery to connecting rod bearings and maintaining maximum oil film thickness. The lower shells are ungrooved to maximize the hydrodynamic oil film, resulting in improved bearing life and a greater safety margin under high loads.

Application:

Ideal for performance street engines, road racing, drag racing, and oval track competition. The design accommodates crankshafts with oversize fillets and excels in medium to high RPM applications where bearing reliability is critical.

Installation Note:

Proper clearancing and fitment verification are essential. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface for optimal performance and longevity.
