Clevite MS651P10 P-Series Main Bearing Set Undersize - 010

Clevite MS651P10 P-Series Main Bearing Set

The Clevite MS651P10 is a precision-engineered main bearing from the legendary P-Series performance bearing family, designed for high-revving engines where reliability and durability are critical. This bearing features a .010" undersize dimension for use with reground crankshafts.

Tri-Metal Construction for Maximum Durability

P-Series bearings utilize advanced tri-metal construction consisting of a hardened steel backing for structural support, a cast copper-lead intermediate layer to withstand heavy loads, and an electroplated babbitt overlay on the running surface for superior bearing characteristics. This three-layer design delivers exceptional conformability, embedability, and fatigue resistance that surpasses original equipment bimetal bearings.

Engineered for High-Performance Applications

As the oldest members of the Clevite 77 bearing family, P-Series main bearings are specifically intended for high-RPM engines where load factors and distortion are elevated. These bearings feature higher eccentricity and a high crush factor to compensate for the demanding conditions found in performance, racing, and heavy-duty applications.

Key Features:

• Tri-metal cast copper lead construction for superior load capacity
• Hardened steel backing provides structural integrity
• Electroplated babbitt overlay ensures excellent bearing surface properties
• High eccentricity and crush factor compensates for high-load distortion
• .010" undersize for reground crankshaft applications
• Suitable for performance, racing, and heavy-duty engine builds
• Manufactured by MAHLE, the trusted name in engine bearings since 1948

Application Notes

This bearing is ideal for engine rebuilds where more demanding use is anticipated, including motorsports, street performance, and heavy-duty applications. P-Series bearings represent a significant upgrade from standard bimetal bearings and are suitable for most OE replacement applications where enhanced durability is desired.
