Clevite MS2318P25MM P-Series Main Bearing Set .25mm Undersize

The Clevite MS2318P25MM is a P-Series main bearing set designed for high-revving engine applications with crankshafts reground .25mm undersize. As part of Clevite's original high-performance bearing family, P-Series bearings are engineered to handle the high-load factors and distortion encountered in performance engines.

Key Features:

• Tri-metal construction with hardened steel backing for superior support
• Cast copper-lead lining engineered to withstand heavy engine loads
• Electroplated babbitt overlay on running surface for excellent wear characteristics
• Higher eccentricity design to narrow bearing contact patterns and maximize oiling
• High crush factor ensures maximum retention in the engine block
• .25mm undersize dimension for use with reground crankshafts
• Full groove oil distribution on most applications for enhanced lubrication
• Reduced overlay thickness to prevent overlay fatigue

P-Series main bearings deliver exceptional conformability, embedability, and fatigue resistance for demanding performance applications. The high eccentricity design provides increased oil flow to rod bearings, helping prevent oil starvation under extreme operating conditions.
