Clevite MS-516P Engine Crankshaft Main Bearing Set

The Clevite MS-516P is a high-performance main bearing set designed for demanding engine applications. This P-Series bearing set features full groove design to maximize oil flow to connecting rod bearings, making it ideal for performance and racing engines where optimal lubrication is critical.

P-Series Performance Features:

• Full grooved main bearing design for maximum oil delivery to rod bearings
• High crush design for superior bearing retention in high-stress applications
• Reduced overlay thickness to prevent overlay fatigue and hen tracking
• Hardened steel backing on rod bearings for added strength and fretting resistance
• High eccentricity design to narrow bearing contact patterns and improve oiling
• TriMetal construction for legendary Clevite strength and durability

Application Benefits:

P-Series bearings are engineered for extreme high-RPM applications where severe rod bore close-in occurs. The increased eccentricity helps narrow bearing contact patterns while ensuring adequate oil supply to rod bearings, preventing the oil starvation that causes surface polishing, smearing, and discoloration. The 180-degree groove in the upper main shell provides optimal oil film development while supplying connecting rods with necessary lubrication.

This main bearing set is ideal for performance builds requiring maximum oil flow, high retention strength, and resistance to bearing fatigue under extreme operating conditions. The design balances oil supply to critical components while maintaining proper oil film thickness for extended bearing life.
