Product Description:

What are the main functions of cylinder liner?

The cylinder liner acts as inner wall of the cylinder and forms a sliding surface for the piston rings while retaining the lubracant within. The most important function of cylinder liners is the excellent characteristics as sliding surface.

Why use cylinder liner?

The cylinder liner prevents compressed gas and combustion gas from escaping. All that is needed is a cylinder liner that is difficult to replace with the high pressure and high temperature in the cylinder.

How do you know if your cylinder liner is bad?

Check the cylinder liner for cracks, freeting or scoring. If any crack, fretting or scoring is detected, the cylinder must be replaced with a new one. If this is not the case, continue looking for cavitation erosion on the liner. Erosion results from poor cooling system maintenance.

How does a cylinder liner work?

A cylinder liner provides a smooth sliding surface that allows the reciprocating motion of a piston. The friction resistance offered by the inner walls of the liner is negligible; this allows the piston rings to slide over the inner walls of the liner.

What are the 3 main types of cylinder liners?

Three basic types of liners are used: hot, dry and finned. The purpose of each type is to protect the piston from heat and impurities using slightly different methods. Cylinder liners are expensive, precisely manufactured products and are primarily purchased from specialty shops.
