Clevite MS-1704A-10 Engine Crankshaft Main Bearing Set

The Clevite MS-1704A-10 is a precision-engineered main bearing set designed to provide reliable crankshaft support in demanding engine applications. This bearing set utilizes Clevite's proven tri-metal construction technology to deliver optimal performance, durability, and load-bearing capacity.

Key Features:

• Tri-metal bearing construction for superior strength and wear resistance
• Optimized grooving design to maximize oil film thickness while maintaining proper connecting rod oiling
• High crush design ensures maximum bearing retention in the housing
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Hardened steel backing provides exceptional structural integrity
• Precision-manufactured to OEM specifications for proper fitment

Performance Engineering:

Clevite main bearings feature strategically designed oil grooves that balance two critical requirements: providing adequate oil supply to connecting rod bearings while maintaining the thickest possible oil film for crankshaft support. The upper bearing shells incorporate a 180-degree groove that effectively supplies oil to the connecting rods, while the lower shells remain ungrooved to develop maximum oil film thickness in the heavily loaded area. This design provides superior bearing life and increased safety margins compared to older full-grooved designs.

Application:

This main bearing set is engineered for engines requiring precise crankshaft support with optimal oil flow characteristics. The tri-metal construction and engineered overlay thickness make this bearing set suitable for both street performance and racing applications where reliability and longevity are essential.
