Clevite MS-2206P-.50MM Main Bearing Set Oversize Performance P-Series

The Clevite MS-2206P-.50MM is a high-performance main bearing set designed for demanding racing and competition engine applications. This P-Series bearing set features 0.50mm oversize dimensions for use with precision-machined crankshafts.

P-Series Performance Features:

• High crush design for maximum bearing retention in extreme conditions
• Reduced overlay thickness to prevent overlay fatigue and "hen tracking"
• Full groove configuration in upper shells to maximize oil flow to connecting rod bearings
• Hardened steel backing for added strength and resistance to fretting
• High eccentricity design to narrow bearing contact patterns and improve lubrication
• TriMetal construction combining durability with performance characteristics

Oil Distribution Technology:

This bearing set utilizes a 180-degree groove in the upper main shell to supply oil to connecting rods while maintaining optimal oil film thickness. The lower shells are ungrooved to provide maximum load-carrying capacity and improved bearing life. This proven design delivers the best balance between oil supply and bearing performance in high-RPM applications.

Ideal Applications:

P-Series bearings are specifically engineered for engines experiencing extremely high RPMs that cause severe rod bore close-in. These bearings are the optimal choice when increased oil flow to rod bearings is critical, or when rod bearing oil starvation is evident through polishing, smearing, or discoloration of bearing surfaces. The higher eccentricity design helps prevent rod bearing failure in demanding competition environments.

The 0.50mm oversize dimension accommodates crankshafts that have been precision-ground for bearing journal restoration or performance modification.
