Sealed Power 7369MA .50MM Engine Crankshaft Main Bearing Set

The Sealed Power 7369MA .50MM Engine Crankshaft Main Bearing Set is an A-Series bi-metal aluminum main bearing set engineered for reliable performance in demanding engine rebuild applications. Designed as a 0.50mm undersize replacement, this set meets or exceeds OEM specifications and is manufactured under ISO and QS certified processes.

Sealed Power's MA-Series main bearings feature a proprietary aluminum-tin alloy bearing surface with a small percentage of silicon added for superior wear resistance. This silicon content also helps polish crankshaft journals during break-in, making these bearings an excellent choice even when the crank surface has not been fully optimized. The bearing surface alloy is bonded to a high-strength 1010 steel backing for structural integrity and dimensional stability.

Key Features:

• A-Series bi-metal aluminum alloy construction for long service life
• 0.50mm crankshaft undersize for use on reground crankshafts
• Silicon-enhanced surface alloy provides greater hardness and wear resistance
• Superior seizure resistance compared to conventional tri-metal bearings
• High-strength 1010 steel backing for improved wall variance control
• Minimizes debris embedding to protect crankshaft journal surfaces
• Meets or exceeds OEM specifications
• Manufactured under ISO & QS certified processes

Sealed Power is a Federal-Mogul brand with a long history of supplying both OEM manufacturers and the professional aftermarket. These main bearings deliver the precision tolerances and material quality required for a successful engine rebuild.
