- Hydraulic Cylinder : Applies Hydraulic Force.- Cylinder Base Plate : For application like lifting

where additional cylinder stability is required.

- Pump : Develops hydraulic pressure.- Hose : Transport hydraulic fluid.- Male Coupler : For quick connection of the

hose to system components.- Female Coupler : For quick connection of the

hose end to the system components.

- Gauge : To monitor pressure of the hydraulic circuit.

The amount of force a

hydraulic cylinder can

generate is equal to the

hydraulic pressure times

the effective area of the

cylinder

Example 1. An RCS-502 Cylinder with 9.63 in2 effective area operating at 8000 psi. will generate what force?

Force = Pressure x Effective Area. = 8000 x 9.63

= 77040 lbs. (35 ton)Example 2. An RCS-1002 Cylinder lifting 14000 lbs. load with effective area of 19.67 in2, what is the operating pressure require?

Force = Pressure x Effective Area. 14000 = Pressure x 19.67

Pressure = 711.75 psi. (50 kg/cm2)

• Couplers should be pressurized only when completely connected.

• Always keep Plastic dust caps on coupler head.

• Thread Sealer : To seal NPT threads use Teflon paste.

• When using: TeflonTape, apply the tape one thread from the end of fitting to prevent it from winding up in the hydraulic system.

• Do not exceed maximum pressure of

10,000 psi.

• Do not handle hoses which are under

pressure.

• When using longer hose length, it is

sometimes necessary to fill the pump
