7.8 Oil selection
All hydraulic oils with a viscosity of approx. 30 to 50 centi-Stokes at 40°C are suitable for the operation of
chuck cylinder. For normal operation, we recommend a viscosity of 46 centi-Stokes at 40°C. This
corresponds to ISO recommendation VG 46 in accordance with DIN 51519, e.g.:
ARAL TU 524 (VG 46)
ARAL TU 508 (VG 32)
SHELL TELLUS C 46 (VG 46)
SHELL TELLUS C 32 (VG 32)
or other branded oils of above qualification.
Attention:
If a VG 32 oil type is used, then it may result in higher leakage of oil supply to the
chucking cylinder (see also operating manual of the manufacturer of chucking
cylinder).
