Mercedes-Benz OM457 Cylinder Block

The Mercedes-Benz OM457 cylinder block is a core component for heavy-duty truck and coach engines, widely applied in long-haul transportation, passenger transport and engineering vehicles. It provides stable rigid support for crankshaft, piston and valve train assembly, meeting the maintenance and replacement demands of fleets with Euro III/Euro IV/Euro V emission OM457 engines.

Built upon Mercedes-Benz classic heavy-duty engine design, this cylinder block adopts high-strength gray cast iron casting technology, with optimized internal cooling water channel and lubricating oil passage layout. It effectively improves heat dissipation and lubrication efficiency, lowering failure risks and extending engine service life under continuous heavy load.

Product Advantages

High Structural Strength

• High-strength cast iron material, strong anti-deformation capacity under long-time high-load operation
