Clevite MS-829VX High Performance Main Bearing Set

The Clevite MS-829VX is a high-performance engine crankshaft main bearing set designed for competition and performance applications. This V-Series bearing set features lead-indium overlay construction on a hardened steel back, offering superior conformability for demanding engine conditions.

V-Series Technology:

• Lead-indium overlay provides excellent conformability with slightly reduced wear resistance compared to lead-tin-copper overlays
• Low to medium eccentricity design for optimal bearing contact patterns
• Hardened steel backing for exceptional strength and durability
• Single-piece thrust bearing construction for reliable performance
• Non-flash plated steel back for improved bearing seating
• Extra clearance (VX designation) provides .001" additional clearance for select fitting

Advanced Bearing Design:

This main bearing set utilizes optimized grooving technology. The upper main shells feature a 180-degree groove that efficiently supplies oil to connecting rod bearings while maintaining maximum oil film thickness. The lower main shells are ungrooved, which allows for a thicker protective oil film and improved bearing life under high loads.

Applications:

V-Series bearings are ideal for builders who have prior experience with lead-indium overlay bearings or applications requiring enhanced conformability. The TriMetal construction combines a hardened steel back, copper-lead intermediate layer, and lead-indium overlay for exceptional durability in high-performance and racing engines.

This bearing set is engineered for performance engines operating across a wide RPM range where reliable lubrication and load distribution are critical for engine longevity.
