Perfect Circle MS590P10 Crankshaft Main Bearing Set 0.010 Undersize P-Series

The Perfect Circle MS590P10 is a crankshaft main bearing set featuring P-Series design with 1/2 groove configuration and 0.010 inch undersize dimensions. This tri-metal cast copper-lead bearing set is engineered for engine rebuilds where more demanding use is anticipated, including heavy-duty applications, motorsports, and street performance vehicles.

Key Features:

• P-Series tri-metal construction with cast copper-lead design for superior load capacity
• 0.010 inch undersize for machined crankshafts requiring oversized bearings
• 1/2 groove design for optimal oil distribution
• High eccentricity and crush factor to compensate for high-load factors and distortion
• Suitable upgrade from bi-metal engine bearings due to increased load capacity
• Versatile replacement suitable for most OE applications

The tri-metal design reduces drag and increases horsepower while withstanding up to 60% higher loads compared to conventional bearings. Perfect Circle P-Series bearings are ideal for rebuilding engines that will experience demanding conditions, providing the durability and performance required for heavy-duty, performance, and racing applications.
