DRY CYLINDER LINERS SLEEVES

DRY CYLINDER LINERS / SLEEVES made of grey cast-iron, manufactured by the "CENTRIFUGAL CAST PROCESS" is acknowledged to be the best method. It possesses the bearing metal qualities that cause skin healing after abrasion and a structure that is readily wetted by oil and retains an oil film. 
Corrosion resistance is further improved by adding Chromium in the metal. In the centrifugal casting process, the molten metals is poured into a metal mould or die which is revolving at a high speed. 
The centrifugal force causes the metal to distribute itself evenly around the die. The resulting castings are of much finer grain structural and free from blow holes or porosity and the hardness is very good. It has enough hardness, toughness strength and wears resistance. 
The allowance for the fitment between liner and bore holes is 0.050 to 0.075mm. these are available in Semi-Finish (SF) and Fully-Finish (FF) condition. The available ranges are suitable for light, medium and heavy duty applications.
