Cylinder liner for Caterpillar D315

The cylinder liner WS-522H acts as the internal wall of the combustion chamber within the engine block. It provides a defined surface for the piston and its rings to travel against during the combustion cycle. This component is responsible for maintaining the seal necessary for compression while facilitating the transfer of heat from the combustion area to the engine cooling system.

This part is compatible with the Caterpillar D315 engine. It is installed directly into the engine block to protect the block structure from the direct friction and heat produced by the piston assembly. Proper installation ensures that the piston rings maintain contact with the wall, which helps manage oil consumption and maintains the required pressure levels within the cylinder.

In heavy machinery engines, cylinder liners are used to create a replaceable wear surface. By housing the piston, the liner manages the high-temperature environment and mechanical stress generated during operation. Replacing these liners allows for the restoration of engine tolerances without requiring the replacement of the entire engine block.
