Clevite MS-1432A-30 Engine Crankshaft Main Bearing Set

The Clevite MS-1432A-30 is a precision-engineered crankshaft main bearing set designed for high-performance and racing engine applications. This bearing set utilizes Clevite's proven TriMetal construction, featuring a steel back, copper-lead intermediate layer, and a protective overlay for exceptional durability under extreme loads and temperatures.

Key Features:

• TriMetal construction provides superior strength and wear resistance
• Optimized bearing grooving design for improved oil film thickness and bearing life
• High crush design ensures maximum retention in the housing
• Reduced overlay thickness prevents overlay fatigue and hen tracking
• Enlarged chamfers provide increased crankshaft fillet clearance
• No flash plating for improved seating characteristics

Performance Design Benefits:

Modern main bearing technology has evolved to remove grooving from lower main shells, resulting in a thicker oil film for the crankshaft to ride on. This design provides a greater safety margin and improved bearing life. The upper main shells retain a 180-degree groove to supply connecting rods with oil while maintaining optimal bearing performance.

Application:

This main bearing set is ideal for performance street engines, racing applications, and engine rebuilds requiring precision-fit components. The design balances optimal oil delivery to rod bearings while maximizing load-carrying capacity and durability in high-RPM operating conditions.
