Installation note:
Lubricate guide shafts monthly with ISO VG32 hydraulic oil.
Maintain 0.3mm minimum clearance between stopper and cylinder head during adjustment.
Use 40μm filtered air to prevent seal degradation.
Avoid side-load forces exceeding 10% of max rating.
For vertical mounting, always use rod-end support brackets (sold separately).
