Installation recommendation:
Use with guided rail systems when stroke/external load ratio exceeds 1:5.
Maintain 0.1-0.3mm alignment tolerance during mounting. Lubricate rod weekly
with thin-film silicone grease in high-cycle applications (>500 cycles/min).
Critical note:
Do NOT exceed 1.2MPa pressure. Avoid side-load forces >30N.
For vertical mounting, reduce maximum payload by 40%.
