Clevite P-Series Main Bearing Set Undersize

The Clevite P-Series main bearing set is an undersize engine crankshaft main bearing for engine rebuilds where the crankshaft journals have been machined smaller. These bearings are also called crankshaft main bearings or engine main bearing sets. They help restore proper oil clearance and support smooth, reliable crankshaft rotation.

Key Features:

• Undersize design for use with reground or machined crankshaft journals
• P-Series construction from Clevite, a long-established engine bearing brand
• Precision-manufactured bearing shells for consistent wall thickness and proper fit
• Designed to maintain correct oil film and oil clearance under load
• Suited to engine rebuilds, restorations, and general replacement

Each part number in the P-Series line is made for a specific engine application and bearing size. Choose the correct undersize for your crankshaft journal measurements. Follow the engine builder's recommended clearances and installation procedures for the best results.
