Clevite MS-590A-20 Engine Crankshaft Main Bearing Set

Carrying on a tradition of durability and dependability, Clevite Bimetal (aluminum) engine bearings feature 100% lead-free aluminum silicon. Engineered with 60% more silicon than comparable competitive replacements, they provide better conditioning of journal surfaces. This results in greater seizure and wear resistance.

• Manufactured from cast copper-lead, increases fatigue strength by approximately 20% compared to powdered metal processes, referred to as sintering, which is used by the competition
• Relatively harder aluminum alloy wears well, interacts closely with journal surfaces for strength
• Recommended for use with nodular iron crankshafts
• Manufactured with 100% bored inside diameters for optimum surface characteristics and consistent precision
• Manufactured to meet or exceed OE specifications
