Clevite MS-2226A-.25MM Engine Crankshaft Main Bearing Set

The Clevite MS-2226A-.25MM is an undersized crankshaft main bearing set designed for precision engine rebuilding and repair. This bearing set features a -.25MM (0.25 millimeter) undersize specification, making it ideal for crankshafts that have been machined or require dimensional compensation.

Advanced Bi-Metal Construction:

• 100% lead-free aluminum silicon alloy composition for environmental compliance and superior performance
• Engineered with 60% more silicon content than comparable competitive bearings for enhanced durability
• Bi-metal design combines a steel backing with an aluminum bearing surface for optimal strength and wear characteristics
• Superior conditioning of crankshaft journal surfaces reduces break-in time and improves long-term performance
• Enhanced seizure resistance protects against catastrophic engine failure under high-load conditions
• Exceptional wear resistance extends bearing life and maintains proper oil clearances

Clevite engine bearings are trusted by professional engine builders and technicians for their proven durability and dependability. The advanced aluminum silicon formulation provides the ideal balance of conformability, embedability, and load-carrying capacity required for modern high-performance and stock engine applications.
