Dry Cylinder Liners Manufacturer

Dry Cylinder Liners / Sleeves
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 is poured into a metal mould or die which is revolving at a high speed. The centrifugal forces causes the metal to distribute itself evenly around the die. The resulting casting are of much finer grain and free from blow holes or porosity. A further important advantage is that the impurities, being lighter than the iron, are forced centrifugally to the bore surface from which they are removed by machining.

Cylinder Blocks / Barrels
Cylinder Blocks / Barrels Air cooled cylinder barrels made from special " Shell Moulding Process" cause wear resisting close grained iron casting and this ensures long life and efficient cooling.
-

Pistons Exporter

Pistons
Pistons are manufactured in a new alloy of exceptional wear resistance and strength at working temperatures. The high conductivity of this material promotes cool running and the light but robust design ensures efficient operation over extended periods. Resistance to wear ring grooves, skirt, and gudgeon pin hole is greatly increased. To ensure dimensional stability in service, all alloy piston castings are correctly heat treated and aged.
-

Piston Pins Manufacturer

Gudgeon Pins / Piston Pins
Gudgeon Pins / Piston Pins for single cylinder engine applications are made from 15MnCr3 grade steel alloy.
All automobile Gudgeon Pins are manufactured from 20MnCr5 grade steel alloy having hardness between 55 to 65 HRC.
All Gudgeon pins are case hardened for high wear resistance surface, coupled with tough cores to resist shock loads and strength to give larger service life.

Pisten Rings
Pisten Rings are individually cast and close material control ensures high tensile strength, resistance to wear and scuffing and to collapse at operating temperatures. Each Ring is double turned and ground to maximum accuracy for smoother performance and low fuel consumption.

Engine Valves
Engine Valves Inlet mace from chrome-silicon alloy steel and exhaust from chrome-nickel-silicon alloy steel ( to operate under high temperature and high stress conditions). Valves are also supplied with liquid nit riding process or hard chrome plating which increases the surface hardening of the Stem. This improves resistance to corrosion with consequent sliding ease

Bushes
Bushes are of four types.

Bi-metal Bushes : The most popular being Steel back with Copper Lead Alloy lining. This is specially used for high loads.

Hard Bronze castings having 90% Copper and 10% Tin are used for several working conditions and heavy pressures specially for applications like Connecting Rod Bushes and Valve Guides.

Red Brass Bushes having 85% Copper, 5% Tin, 5% Lead and 5% Zinc are generally used for water pump Impellers and Slow Speed Engines.

Valve Guides Manufacturer
View Enlarge
Valve Guides
Valve Guides are made from two kinds of material

1) Grey Cast Iron

2) CuZnAl-alloy

GREY CAST IRON of perlitic structure with high phosphorous content. The perlitic structure and the reticular phosphide distribution along with the good graphite formation give high wear resistance and improved running properties in poor lubrication condition.

CuZnAl-alloy Guides are with excellent wear resistance and low coefficient of friction. Used for highest stressed guides.

All our Cast Iron Guides are manufactured having minimum hardness of 93 HRB (200 BHN).

Engine Bearings Manufacturer

Engine Bearings
“ARROW” Brand Engine Bearings are made up of best quality steel back lined with different kinds of Alloys best suitable for the applications for which the bearings are used.

With an experience of over 50 years we have developed 4 types of different Alloys which are then bonded to a steel back to produce the finished product.

A bearing surface has to be strong to withstand high oil filling pressures. It needs to be hard to minimize wear and prevent failure from fatigue.

In contrast, a bearing surface needs to be soft to allow the bearing to tolerate the shaft and sustain when the Cylinder Block distortion occurs and thereby protect the journal as well from damage by absorbing hard foreign particles. The Bearing materials being used by us are:
