Clevite MS-2245A-.50MM Crankshaft Main Bearing Set Undersize

The Clevite MS-2245A-.50MM is an undersize crankshaft main bearing set engineered for demanding engine rebuilds. This precision-manufactured bearing set features Clevite's advanced bi-metal construction with a steel backing and aluminum-silicon bearing surface, designed to deliver exceptional durability and performance in high-stress applications.

Key Features:

• 100% lead-free aluminum-silicon alloy bearing material for environmental compliance
• 0.50mm undersize for use with reground crankshafts
• 60% higher silicon content than competitive bearings for superior journal conditioning
• Bi-metal construction combining steel backing with aluminum bearing surface
• Enhanced seizure resistance to prevent catastrophic bearing failure
• Improved wear resistance for extended engine life
• Precision tolerances for proper oil clearance and bearing crush

Clevite engine bearings are trusted by professional engine builders and mechanics for their consistent quality and reliability. The increased silicon content in these bearings actively conditions crankshaft journal surfaces during operation, creating smoother surface finishes that reduce friction and wear. This undersize bearing set is specifically designed for crankshafts that have been machined 0.50mm undersize during rebuilding.
