cylinder liner

  • Shri Ram Engineers are manufactures of full range of marine cylinder liners and all types of marine industrial products. OEM quality marine cylinder liners are developed as per customer’s requirement including the specified chemical and metallurgical specifications. These marine cylinder liners are developed in gray cast iron using centrifugal casting and utilizing special compositions to enable both the wear resistant properties as well as enhanced lubrication. We ensure technological standards in our manufacturing process which includes casting as per modern technology. Bore size for the marine cylinder liner ranges from to 180mm to 400mm, we also provide a semi-finish or finished marine cylinder liner as needed in various types of marine engines. Casting capacity weight ranges from 150kg to 500kg. And for heavy marine cylinder liner, we maintain the following chemical composition:-
  • Carbon::2.80-3.50%
  • Silicon::1.70-2.30 %
  • Manganese::0.60-0.90 %
  • Chromium::0.20-0.50 %
  • Copper:: 0.20-0.50 %
  • Sulphur::0.15 Max. %
  • Phosphorus::0.15 Max. %
  • Molybdenum::0.20-0.50 %
  • Nickel::0.08-0.25 %
  • Hardness is maintained during various kinds of casting process, ranging from 220 to 280 BHN. Annealing stress is relieved after rough machining. We can provide chrome plating, phosphating, nitriding etc. as per the client's specifications.

  • Pistons up to 350mm diameter are developed.
  • Material used includes aluminum LM 13, graded cast iron etc.
  • Die casting for piston is also provided according to customer requirements.
  • The piston helps in giving compression to the engines, improving efficiency.

piston ring

  • We manufacture piston ring with up to 680mm diameter and is made from special cast iron, piston rings are used for sealing the gap between a piston and the cylinder wall. Its main features are:
  • Helps in sealing of combustion or expansion chamber
  • Supports heat transfer from piston to cylinder wall
  • Regulates engine oil consumption
  • Types of piston ring includes, top compression ring (rectangular ring, keystone ring, half keystone ring), intermediate ring (napier ring undercut, scraper ring stepped) and oil control ring (slotted oil control ring, beveled-edge and double beveled oil control ring).
  • Materials for manufacturing the piston rings includes, chrome plating, Ductile Iron (S G Iron), Steel, Phosphor Bronze, Sintered Iron, Sintered Bronze, Brass, Inlaid Moly coating, Copper Alloy Coating, Ptfe Coating etc.
