Clevite MS154P20 P-Series Main Bearing Set Undersize - 020

The Clevite MS154P20 is a P-Series main bearing set designed for high-performance and high-revving engine applications. This bearing features .020 inch undersize dimensions for use with reground crankshafts.

Key Features:

• TriMetal construction with cast copper-lead for superior fatigue strength
• Precision steel backing provides structural support and strength
• Electroplated babbitt overlay on running surface for excellent wear characteristics
• High crush factor ensures maximum bearing retention and proper seating
• High eccentricity design compensates for bore distortion under load
• Reduced overlay thickness prevents fatigue in high-stress applications
• 360-degree oil grooves on lower bearings for continuous lubrication

Clevite P-Series bearings are the traditional choice for high-performance builds, offering exceptional conformability, embedability, and fatigue resistance. The TriMetal design combines the strength of copper-lead with the surface qualities of electroplated babbitt, making these bearings ideal for engines that experience high loads and sustained high RPM operation.
