Clevite MS-829A-10 Engine Crankshaft Main Bearing Set

The Clevite MS-829A-10 is a high-performance engine crankshaft main bearing set designed for demanding automotive applications. This precision-engineered bearing set provides reliable protection and optimal oil film development to keep bearing surfaces properly separated from the crankshaft during operation.

Key Features:

• TriMetal bearing construction for exceptional strength and durability
• Optimized 180-degree upper shell grooving for ideal oil distribution to connecting rods
• Ungrooved lower shells maintain maximum oil film thickness for improved bearing life
• High crush design ensures maximum bearing retention
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Engineered for performance and racing applications

Technical Design:

This bearing set features advanced grooving technology that balances lubrication needs with bearing performance. The upper main shells incorporate a 180-degree groove that efficiently supplies oil to the connecting rod bearings while maintaining optimal oil film pressure. The lower main shells remain ungrooved to develop the thickest possible oil film, providing greater safety margin and extended bearing life under high-load conditions.

Performance Applications:

Clevite main bearing sets are available in multiple series (P-Series, H-Series, K-Series, V-Series, and M-Series), each engineered for specific performance requirements ranging from street performance to professional racing. The bearing design minimizes horsepower loss while reducing peak oil film pressure transmitted to the bearing surface. These bearings are ideal for builders who demand precision-engineered components that deliver consistent performance under extreme operating conditions.

Clevite bearings are trusted by engine builders worldwide for their proven reliability in high-RPM, high-load applications where bearing failure is not an option.
