Hydraulic & Pneumatic Cylinders


Hydraulic & Pneumatic Cylinders

What is hydraulic cylinder and what is the purpose of hydraulic cylinder?

Hydraulic cylinder is used to convert hydrostatic energy into mechanical energy. They can produce work same as motors and actuators. Hydraulic cylinders are different from hydraulic motors but cylinders have linear movement than rotary movement. The force (F, Newton) in the hydraulic cylinder is directly proportional to the maximum operating pressure (P, Bars) and area (A, Cm2) of the piston.

Mathematics behind hydraulic cylinders, F=P*A (in Bars or Kg/cm2)

The area of the cylinder is difference between the area of the piston and the piston rod. The set pressure, cylinder with larger area will produce larger force.

We manufacture good quality single and double acting types hydraulic/pneumatic cylinders as follows:

1. Tie Rod Cylinders
2. Routine Cylinders
3. Customised Hydraulic & Pneumatic Cylinders as per drawing

There are variety of mounting types as follows:

1. Fork Mounting
2. Foot Mounting
3. Front/Back Flange Mounting
4. Center Trunion
5. Pivot Calavious Mounting

The stroke length is up to 6000mm in conventional types and up to 24000mm in telescopic type.
– Maximum working pressure from 10 kg/cm2 to 250 kg/cm2 with maximum bore diameter of 800mm for hydraulic cylinders.
– For pneumatic cylinders pressure ranging from 2 kg/cm2 to 15 kg/cm2.

Cylinder body – Made from alloy steel tubing with micro finish bore.
Cylinder head – Through bored and grooved to provide concentricity to common center line for the body, rod and gland.

Ports – Provide unobstructed flow without interference from the gland.
The Cap – Also machined for concentricity
Piston Rod – Made from special alloy steel and induction case hardening up to 54 RC .
Seals – All dynamic seals and elastromeric design to seal with minimum friction.
Piston – With wide surface contacting cylinder barrel to reduce bearing loads during mechanical deflection.
