9.4 Lubrication
The precision grippers are lifetime lubricated and can be operated with oil-
lubricated or non oil-lubricated compressed air.
Compressed air specification
Dry (condensation-free)
Filtered (40
μ
m filter for oil-lubricated air)
Filtered (5
μ
m filter for oil-lubricated air)
If the precision grippers are operated with lubricated compressed air, we
recommend that you use the following types of oil:
Oil type
Festo Special oil
Shell Tellus Oel C 10
Avia Avilub RSL 10
Mobil DTE 21
BP Energol HPL 10
Blaser Blasol 154
Esso Spinesso 10
Oil quantity
: 5-10 drops of oil per 1000 ltr. Compressed air
Viscosity range
: 9-11 mm2/s (= cST) at 40°C, ISO class VG 10 acc. ISO 3448
NOTICE
Risk of damage to property!
The operation of the gripper modules with oil-lubricated compressed air
causes the factory primary lubrication to be washed out. Therefore, it is
absolutely essential that the gripper modules continue to be operated with oil-
lubricated compressed air in order to avoid damage to the rotary modules.
Once the gripper modules have been operated with oil-lubricated
compressed air, they
may never
be operated without oil-lubricated
compressed air.
NOTICE
Danger of corrosion!
When used in an ionised air environment (e.g. high voltage
processors/coronisation), the precision grippers can corrode.
Regularly apply lubricant to open flanges/shafts as well as guides and
pliers.
We recommend monthly cleaning and lubrication according to AFAG
standard: - Staburax NBU8EP (flat guides)
- Blasolube 301 (piston rod)
