INSTALLATION PROCEDURE

The equipment must be installed in the accordance with the 

laws, guide lines and rules applicable within the country.

As per ISO 8573 we required air quality as below.

1.  Particle size < 5 μ (class 5)

2.  Pressure dew point < -20°C (class 3) for actuator 

3.  Pressure dew point < -40°C (Class 4) for positioner

4.  Concentration of total oil < 5 mg/m

WARNING:

OPERATING CYLINDERS OVER TEMPERATURE OR PRESSURE LIMITS 

WILL RESULT IN DAMAGE TO CYLINDERS.

CAUTION: DO NOT DISMANTLE THE CYLINDER WHILE 

OPERATION IS IN LINE. DO NOT ALLOW DIRTY AIR OR FLUIDS 

TO GET INTO THE CYLINDER. USE FILTER UNIT (FILTER SIZE 

40ΜM, 3°C) FOR DUST AND MOISTURE REMOVAL. 

NOTE: Ensure the installation meets the legal and regulatory 

requirements of the country and state of use.The cylinder 

assembly should be left in the original packing until it is 

required for the use. The metallic pipe connections should 

be rinsed with degreasing or by grease dissolving liquids 

or agents, before being connected to our cylinder. Flush all 

pipes with 4 kgf/cm

 air for at least 1/2 hour. Lubrication is 

not necessary. (Maintain once started oil mist lubrication. As 

per ISO 3448 recommended oils are NUTO H 32, VG 32. Oil 

viscosity 32 cSt at 40°C). Operating pressure range 1-10 bar. 

Operating temperature range -20°C to +70°C

1.  Pneumatic system is suitable for operation with 

compressed air between 1-10 bar. Usually the sizing is 

done at the air pressure availability confirmed by the 

client. (Hydraulic pressure maximum of 10 bar on request)

2.  Hemp filaments, jute or even teflon ribbons are 

normally not required, As the part connections are 

accurately threaded. By chance, if any of these or any 

other tightening medium get into the operational area 

inside the cylinder, possible damage of the cylinder 

could not be ruled out.

3.  The mounting holes size and bolt size circle are 

confirming to ISO 6431 / ISO 15552 norms. The threaded 

holes are ISO metric coarse and as ISO 6431 / ISO 15552. 

(Refer catalogue)

4.  Clean all pipes and tube fittings thoroughly with suitable 

means. As even when brand new pipes are fitted, unclean 

interior are quite covered with dirt and dust.

5.  Avoid impact on the cylinder. These may happen during 

transportation/ erection/ mishandling.

6.  Align properly the rod axis with the load and direction 

of movement when connecting. If not properly aligned, 

the rod and tube may be twisted and damage may be 

caused due to wear on areas such as inner tube surface, 

bushing, rod surface and seals.

7.  All accessories mountings of cylinders are well 

lubricated before dispatch. After removing pin and 

circlip store them in clean box. Install pin and circlips 

without damaging bore.

8.  When an external guide is used, connect the rod end 

and the load in such a way that there is no interference 

at any point within the stroke.

9.  Cushioning – 

When stroke comes to an end, cushioning allows air to pass 

through cushioning port and thus decelerate the piston 

before it strikes the end cap which lowers the stresses on 

cylinder components and reduces vibration transmitted to 

the machine structure.

If cushioning is not provided then air passes through 

exhaust port only. When stroke comes to an end, piston 

strikes the end cover with some acceleration, giving rise 

to knocking noise, stresses on cylinder components and 

vibration transmitted to the machine structure.

Perfect pneumatic cushioning produces minimal noise from 

end cover contact, and minimum piston deceleration time.  

To achieve perfect cushioning, ensure cushioning screw is 

full open at the time of installation. Operate cylinder in full 

forward to full back. Now keep on tightening cushioning 

screw till cylinder stops knocking. This will give maximum 

life to your equipment and to pneumatic cylinder.
