9. Maintenance, upkeep
9.1 Maintenance:
The through-hole type actuating cylinder with distri-
butor requires no regular maintenance.
9.2 Upkeep:
Once a year or whenever there is a loss of pres-
sure, remove the cylinder from the spindle and di-
sassemble it. Clean all parts and check them for
wear. It is generally good practice to replace all
sealing elements or at least those subject to dyna-
mic stress. For this reason, 1 set of the sealing ele-
ments identified in the parts list and a supply of
consumable items should be stocked at all times.
To reassembly the cylinder, reverse the disassem-
bly procedure. Make sure that marked parts or
parts requiring a specific position are assembled in
the intended position in order to avoid unbalance or
malfunctions.
Important: Do not damage seals with tools or sharp
edges.
To keep the cylinder damaged, it is good practice to
rebalance it after reassembly. At speeds over 3000
rpm, this precaution is a ”must”. On request, reas-
sembled cylinders will be rebalanced against
charge at the Röhm factory or on the customer’s
premises by one of our fitters with the aid of a
portable balancing machine.
Reassembled cylinders should at least be checked
for vibrations which were not present before the
cylinder was disassembled.
This is all the services which the cylinder requires.
