Clevite MS-1545A-30 Engine Crankshaft Main Bearing Set

The Clevite MS-1545A-30 is a high-performance engine crankshaft main bearing set designed to deliver exceptional durability and reliability in demanding applications. This complete bearing set provides the foundation for smooth crankshaft operation and extended engine life.

Advanced Bi-Metal Construction:

Clevite's bi-metal aluminum engine bearings feature a 100% lead-free aluminum silicon alloy construction that meets modern environmental standards without compromising performance. The advanced metallurgy incorporates 60% more silicon content compared to competitive replacements, which enhances the bearing's ability to condition crankshaft journal surfaces during operation.

Key Features:

• Complete main bearing set for crankshaft installation
• Bi-metal aluminum construction with superior silicon content
• 100% lead-free design for environmental compliance
• Enhanced journal surface conditioning capabilities
• Improved seizure resistance for reliable operation
• Superior wear resistance for extended bearing life
• Precision-manufactured to OE specifications

Performance Benefits:

The higher silicon content in these Clevite bearings provides multiple performance advantages. Better journal conditioning helps maintain optimal clearances and oil film thickness throughout the bearing's service life. The improved seizure resistance protects against catastrophic failure during high-load conditions or momentary oil starvation, while the enhanced wear characteristics extend time between overhauls.

Clevite continues their legacy as a trusted name in engine components, providing professional-grade bearings suitable for stock rebuilds, performance applications, and demanding commercial use.
