Clevite MS-1949P High Performance Main Bearing Set, P-Series, Flanged

The Clevite MS-1949P is a high performance engine crankshaft main bearing set. It is a flanged design that includes a .15mm oversize length, and it is supplied for .25mm and .50mm undersize crankshaft journals.

Key Features:

• High performance main bearing set for engine crankshafts
• Flanged bearing design with .15mm oversize length
• Set covers .25mm and .50mm undersize applications
• P-Series construction, the oldest series of Clevite high performance bearings
• P-Series main sets are typically full grooved to maximize oil flow to the rod bearings
• High crush for maximum retention and a reduced overlay thickness to help prevent overlay fatigue

About P-Series Bearings: Use P-Series mains where higher eccentricity is desired to narrow bearing contact patterns and to increase oiling to the rod bearings. P-Series parts have unique core part numbers that differ from the standard passenger car and light truck parts for the same application, even though those parts may also carry a P suffix.

Bearing Grooving: Grooving in a main bearing exists mainly to supply oil to the connecting rods. Clevite testing found that a simple 180-degree groove in the upper shell is the best overall design. Extending the groove into the lower half takes away from upper bearing performance without benefiting the lower half, and longer grooves increase horsepower loss and peak oil film pressure.

Choose the Clevite MS-1949P for performance and competition engine builds where increased oiling to the rod bearings and secure bearing retention are priorities.
