Reliable Production For Their Uninterrupted Service


Hydraulic cylinders are the actuators for high pressure application. Fluid (Hydro) is the media used to actuate the actuators and hence the actuators are termed as Hydraulic Cylinders. Fluid is a non compressible media. Hence it transmits all the pressure applied on it. Therefore it exerts maximum force in application. The hydraulic cylinders are designed for high pressure application and hence the size of the cylinders is compact as compared with the conventional pneumatic cylinders.

Tie Rod Construction

Mounting Types:
1. Front Flange
      2. Rear Flange
      3. Clevis
      4. Foot
      5. Trunion

Actuation Media:
Mineral oil

Construction Advantage:
1. Very Easy to dismantle and
     assemble during maintenance.
      2. Avoids duplication in
     manufacturing process.
      3. Cost of production is

1. Machine Tool
     (Jigs, Fixtures, Clamping)
      2. Automation
      3. Robotics.
      4. Material Handling
      5. Injection Moulding
      6. Pressure Die Casting
      7. Mobile Hydraulics.
      8. Scissor Lifts.

All the loose parts in a hydraulic cylinder are tied together with high tensile threaded rods. Hence the type of the cylinder is called as Tie Rod Construction. The cylinders are designed to withstand normally up to 300 Kg/Sq. Cm. (4250 Lbs/Sq. Inch). Hydraulic seals in a cylinder play a vital roll in its application. The company selects the seals to suit the working conditions of the cylinder.

Water Based

Mounting Types:
1. Front Flange
      2. Rear Flange

Actuation Media:
    Water + Glycol

1. Low Pressure Die Casting          
      2. All the areas where the
    application is near direct heat.


In Low Pressure Die Casting (LPDC) application normally the dies are pre-heated with flame. Oil being an inflammable media, chances of fire catching is more. Hence a fluid which is less fire hazardous is used as actuation media. A compound of Water + Glycol is normally used in lieu of mineral oil. Hence the cylinders are termed as Water Based Cylinders. The features of these cylinders are same as Tie Rod Construction. The cylinders are designed to withstand normally up to 160 Kg/Sq. Cm. (2250 Lbs/Sq. Inch). A special types of hydraulic seals are used in these type of cylinders.

Threaded Neck Mounting

Mounting Types:
     Threaded Neck

Actuation Media:
     Mineral oil

     High Pressure Die Casting (HPDC)

Available Bore:
50 mm
      63 mm
      73 mm
      80 mm
      100 mm
      110 mm
      125 mm

Maximum Stroke:
250mm up to 80mm bore cylinders
200mm above 100mm Bore cylinders

Max. Working Pressure:
200 Kg/Sq. Cm (2800 Lbs/Sq. Inch)

High Pressure Die Casting (HPDC) is an area where bigger castings are cast with many intricacies. Many cores are involved to form internal cavities in the castings. The cylinders are directly mounted on the dies in application. The cylinder parts are machined, since carburized material. Piston Rings are used as piston seals. A set of Chevron packing is used as rod seal. The cylinder mounting is on the threading provided on the projection (Neck) of the cylinder body itself. Hence the cylinders are termed as Threaded Neck Mounting.

Neck Mounting Combination

Mounting Types:
 Threaded Neck

Actuation Media:
Mineral oil

     High Pressure Die Casting (HPDC)

Available Bore:

Maximum Working Pressure:
     160 Kg/Sq. Cm
     (2250 Lbs/Sq. Inch)

     Refer Tie Rod Construction

Since a lot of pressure is exerted from Pressure Die Casting Industries, the company designed and developed hydraulic cylinders with combination of Threaded Neck Mounting and standard Tie Rod Construction. The main features of the cylinders are as follows.

1. Cushioning by default at both ends.
2. Viton seals by default.
3. Construction material is same as Tie Rod
4. Honed tube & Hard Chrome plated shafts
    improve the seal life.
5. Total weight of the cylinder is less as
    compared with Neck Mounting Cylinder.
6. Internal pressure drop minimal since
    piston seals are used in lieu of piston
7. Cylinder cost is controlled.


Special Cylinders

Spl Cylinder - Double Ended

Spl Cylinder - Long Stroke Cylinder


Many times the customer needs a cylinder for a special application. The standard cylinder becomes special because:

1.  The relation of application point to
     mounting point is different.
2.  The construction material of the cylinder
     should be non corrosive. (SS 304)
3.  Mounting style of the cylinder to suit a
     special profile.
4.  Space constraint.
5.  Mounting with extended tie rods.
6.  Double ended application.
7.  Simultaneous application on both ends.
8.  Different combination of cylinder bore
     and rod for specific pushing and pulling.
9.  Gates shearing in foundries
10. Pipe Crimping for Hydraulic Hoses
11. Robotic applications.
