Product Description:
We offer a high reliable range of liners & sleeves, which find applications in Marine Engines, Main Engine, industrial and diesel engine, Compressors, automobiles, tractors etc. .
We manufacture these liners in various dimensions ranging:
Outside Dia - 50 mm to 700 MM Dia
Max Length - 1500 MM
Weighting - 1000 Kg
We also accept the customized orders of our clients and manufacture these products in accordance with the samples and drawings with the given material & coating.
Cylinder Liners - Sleeves, made of gray cast-iron, ought to have desired casting and machining qualities, viz. strength, toughness, hardness and wear resistance. These are mainly of two types – Dry liner-sleeves and Wet liner-sleeves. The liners-sleeves are ‘cast-in fit’, force (press) fit or slip fit. The interference between its outer diameter and bore-hole walls depends on fit-type from 0.050 to 0.075 mm. These are available in wide range suitable for light, medium and heavy duty application.
In order to meet with industrial quality standards, we manufacture these liners & sleeves from sand casting and centrifugal casting, which enables us to maintain the uniform hardness all over. Apart from this, we also keep into consideration various factors including distortion-less bore and low thermal expansion to meet with the requirements of our clients. These liners & sleeves are available in semi-finished as well as full finished sizes. Cross honing is done on the full finished products to make the inner bore distortion-less. The inner bores are cross honed to provide maximum smoothness to the surface, which in turn reduces friction, when this inner bore is contacted with Piston Rings.
WET CYLINDER LINERS 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.
Quality:
- Centrifugally cast cylinder liners of actual quality along with precise machining.
- A very good plateau honing and cylindrical grinding that matches the geometrical parameters.
- Manufactured with chromium and nickel elements maintaining the BS4K6 material standard.
- Stringent material along with microstructure analysis of all the batches individually.
- Complete dimensional inspection of the finished components included in the process.
- Inspection of honing angle, structure and surface roughness at a random.
- Tests of profiles, tensile strength and crack detection at regular intervals in a random way.
- Manufacturing experience for the past 25 years and an expertise with single roof manufacturing outlet.
- A very wide range and suitable for up to 1500 models for worldwide cars, trucks, tractors and industrial engines.
- Can produce liners in bulk as well as small quantity in our patch production unit.
Process
In the centrifugal casting process, the molten metal is poured into a metal mould or dies which is revolving at a high speed. The centrifugal force causes the metal to distribute itself evenly around the die. The resulting casting is of much finer grain and free from blow holes or porosity.
