MAINTENANCE

NOTE: The cylinder must be removed from installation 

prior to maintenance. All the connections/ports have to 

be disconnected prior to disassembly. All the mountings, 

accessories and spare parts used or replaced must be 

original from RMEBS.
RMEBS recommends “RMEBS V09” grease for greasing. 

Wherever asked, use 7649 primer (dryer) for drying and 242 

loctite for tightening effect. Apply the grease with soft brush 

or similar. In case of any difficulty consult RMEBS distributor.
1.  The RMEBS pneumatic cylinder CC series (Ø200 – Ø350) 

is designed to operate for piston travel of 20,000 km 

without servicing. 

2.  Install, operate and maintain as per the instructions and 

recommendations of this manual.

3.  Any deviation from the above will cease the 

responsibilities of RMEBS.

Failure

Verify

Remedy

a.   Cylinder 

is not 

operating

1.  Compressed air is not 

available

Make it available

2.  Side thrust is too high

Align the component 

properly

3.  Operating below the 

lower speed limit

Eliminate cause of lower 

load fluctuation

4.  Direction control valve 

is not operating

Make sure that the pressure 

and supplied voltage for 

direction control valve are 

as per rating

5.  Connected device 

(Gate valve, globe 

valve, damper, etc.) get 

stucked

Do maintenance of 

connected device

6.  Load factor is too high

Raise pressure or use 

larger cylinder

7.  Speed controller is 

meter-in control

Change to meter-out 

control

b.   Cylinder 

opeartes too 

slow

1.  Air pressure is 

insufficient

Check for the leakge and 

make it leak proof

2.  Air flow is insufficient 

Check pressure drop on 

AFR gauge and make 

sure that tube sizes are 

proper
