- 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:-
- 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.
- 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.
- We produce perfect piston pins (gudgeon pin) which are duly heat-treated with 60 HRC with smooth grinding/mirror finish.
- Materials include Alloy Steel grade SAE8620 / EN353 / 16mncr5 etc.
- Customized piston pins are developed according to customer's requirement.
- We develop both inlet valves as well as exhaust valves which are made by gathering Metal upset forging process and bimetallic valves are friction welded. Various processes such as chrome flash on stem, stellite on the seat and tip area with nitriding-tuftriding etc. processes.
- EN24(BS817M40), EN52(BS401s45),21-4N(BS349S52) etc. materials are used.
- Our valve guides are made with graded cast iron and with proper specification. They are heat treated for toughness and machined with high precision. Closely maintained inner-outer diameter with highly smooth inner surface and finely grinded outside ensures correct fitment.
- Non ferrous valve guides made from phosphorus bronze and special alloys are offered.
- Tip induction hardening is done to ensure high wear & tear.
- We present a wide range of valve seat inserts which are made from forging / casting with nickel, chrome, cobalt and iron based alloys that display superior wear and heat resistant properties. Valve seat inserts can be used in more than 60 type of engines running by light fuel oil, heavy fuel oil as well as natural gas with light-load high speed and heavy-load high speed respectively.
- We provide a wide range of fuel injection parts and fuel cams and also offering plunger barrel, nozzle, delivery valve. They include a lot of dimensions and specifications. These precision engineered fuel injection parts and cams are manufactured by our team of engineers and technical experts at our state-of-the-art manufacturing unit.
- Other parts include fuel pump rake, pipe, stud, automizer(nozzle holder) and pinion.
- Our quality rocker arms are made from carbon steels, case hardening steels, or as per specifications by forging & investment casting process. rocker arms with chilled surface profiles are offered as well. Correct hardness and heat treatment cycle with accurately machined parameters ensures the trouble-free performance.
- Other products include rocker arm lever.
- High precision big end bearings, main bearings, and bushings are offered in bi-metal (copper-lead based & babbitt/white metal based) & tri-metal (steel backed copper-lead with over lay of babbitt metal). We manufacture bearings and bushings with centrifugal as well as by sintered process, made from high grade materials they are durable in quality assuring higher performance and they are widely used as replacement in various marine engines and diesel generators, compressors & earthmovers.
- Made from aluminum pressure die casting these turbo charger components are used in various marine engines and diesel generators.
- Components include bearing, nozzle ring, sealing bush etc.
