Clevite MS1642P10 P-Series Main Bearing Set Undersize - 0.010

The Clevite MS1642P10 is a P-Series main bearing set featuring 0.010 inch undersize dimensions for precision engine rebuilding. Part of the legendary Clevite 77 bearing family, P-Series bearings are engineered specifically for high-revving engines where demanding performance is required.

Construction and Design:

• Tri-metal cast copper lead construction for superior strength and durability
• Hardened steel backing provides structural support under high loads
• Cast copper lead lining withstands the extreme forces of engine operation
• Electroplated babbitt overlay on running surface for excellent bearing surface qualities
• Higher eccentricity and high crush factor compensate for high-load factors and bore distortion

Key Features:

• 0.010 inch undersize for crankshaft machining or wear compensation
• Enhanced conformability and embedability characteristics
• Superior fatigue resistance compared to competitive bimetal bearings
• Extended oil grooves on most applications for improved lubrication
• Manufactured to meet or exceed OE specifications

Ideal for engine rebuilds where heavy duty use, motorsports, or street performance applications are anticipated. The tri-metal design offers increased load capacity, making it an excellent upgrade from standard bimetal bearings. Clevite bearings have been the choice of performance engine builders and NASCAR champions since 1948.
