Cylinder liner for Scania MD70B

The cylinder liner, part number 88868110, serves as the internal wall of the cylinder block in the Scania MD70B engine. It provides a precise surface for the piston and its rings to slide against during the compression and power strokes. By maintaining this interface, the component helps manage the thermal energy produced during combustion and transfers heat away from the piston assembly to the engine block cooling system.

This component is compatible with the Scania MD70B engine model. It is engineered to maintain the specific tolerances required for proper piston movement and effective sealing within the combustion chamber. Proper installation ensures that the engine maintains its compression levels and prevents oil bypass, which is necessary for the efficient operation of the engine under load.

In heavy machinery and industrial engines, cylinder liners are used to define the bore of the cylinder. They act as a replaceable wear surface that protects the engine block from direct contact with the piston rings. This design allows for the restoration of cylinder geometry during engine overhauls without requiring the replacement of the entire engine block.
