Perfect Circle MS1106P P-Series Engine Crankshaft Main Bearing Set

The Perfect Circle MS1106P is a high-performance P-Series engine crankshaft main bearing set designed for demanding applications. This bearing set is part of the Clevite 77 family and is engineered specifically for high-revving engines that require superior durability and oil flow characteristics.

Key Features:

• P-Series tri-metal construction with steel back, cast copper lead lining, and electroplated babbitt overlay
• Full grooved design on both upper and lower halves to maximize oil flow to connecting rod bearings
• High eccentricity and high crush factor to compensate for high-load factors and distortion
• Reduced overlay thickness to prevent overlay fatigue (hen tracking)
• Hardened steel back provides maximum retention and resistance to fretting
• Designed for performance engines with exceptional conformability and embedability

The MS1106P main bearing set delivers the degree of conformability, embedability, slipperiness, and fatigue resistance required for high-performance applications, surpassing standard original equipment bearings. The full groove design ensures optimal lubrication to connecting rod bearings under demanding operating conditions.
