4. General Notes
-
Design Standards: Yuken products comply with three design standards: Japanese JIS (no suffix), European (80 standard), and North American (90/950 standard).
-
Fluid Requirements: Recommended hydraulic fluid is ISO VG 32 or VG 46 petroleum base oil; special seals (prefix “F-“) are required for phosphate ester fluids.
-
Contamination Control: Hydraulic fluid contamination should be within NAS 1638 Grade 11 (20 μm or less) to avoid component damage.
