Clevite MS-1702A-.50MM High Performance Crankshaft Main Bearing Set

The Clevite MS-1702A-.50MM is a high-performance crankshaft main bearing set designed for demanding racing and performance engine applications. This oversized bearing set (.50mm oversize) features Clevite's proven TriMetal construction, delivering exceptional strength and durability under extreme operating conditions.

Key Features:

• TriMetal bearing construction for superior strength and longevity
• .50mm oversize dimension for machined crankshaft journals
• Optimized upper shell grooving design for maximum oil film thickness
• High crush design ensures positive bearing retention
• Reduced overlay thickness prevents overlay fatigue and hen tracking
• Enlarged chamfers provide clearance for oversize crankshaft fillets
• Non-flash plated for improved bearing seating

Performance Engineering:

Clevite's main bearing design features a 180-degree groove in the upper shell, which has been extensively tested to provide the best overall performance. This configuration maintains optimal oil film pressure while ensuring adequate oil supply to connecting rod bearings. The lower shells are ungrooved to maximize load-bearing surface area and oil film thickness, resulting in improved bearing life and increased safety margins.

This bearing set is engineered for engines operating in medium to high RPM ranges and is compatible with crankshafts featuring oversize fillets. The advanced design minimizes horsepower loss while maintaining proper lubrication throughout the engine's operating range.
