Clevite MS-2028A Engine Crankshaft Main Bearing Set

The Clevite MS-2028A is a precision-engineered crankshaft main bearing set designed to provide reliable lubrication and durability in performance engine applications. This bearing set features optimized grooving technology that balances oil delivery to connecting rods while maintaining maximum oil film thickness for superior bearing life.

Key Features:

• TriMetal bearing construction for exceptional strength and durability
• Optimized 180-degree upper shell grooving for efficient oil distribution
• Ungrooved lower shells maintain maximum oil film thickness under load
• High crush design ensures positive bearing retention
• Reduced overlay thickness prevents overlay fatigue
• Precision-engineered for proper shaft clearance and alignment

Engineering Design:

Clevite main bearings utilize advanced grooving technology based on extensive performance testing. The upper main shells feature a 180-degree oil groove that efficiently supplies connecting rod bearings while the ungrooved lower shells maximize load-carrying capacity. This design develops a thicker oil film for improved safety margins compared to fully-grooved vintage designs, while reducing horsepower loss and peak oil film pressure.

Application Notes:

This main bearing set is engineered for engines requiring OEM replacement specifications with performance-grade materials. The bearing design ensures proper oil flow to connecting rod journals while maintaining optimal clearances for reliable operation across varying load and temperature conditions. Compatible with standard crankshaft journal sizes and fillet radii.

Clevite bearings are manufactured to strict tolerances and quality standards, making them suitable for both street performance and professional racing applications where bearing reliability is critical.
