Installation guidelines:
For vertical mounting, use locking nuts on piston rod threads.
Maintain 0.5-1 mm clearance between magnetic sensor and cylinder body.
Lubricate every 3 months in high-cycle applications (≥500,000 cycles/month).
Avoid side load exceeding 30N.
For horizontal mounting over 500mm stroke, recommend using slide guides.
Not suitable for vacuum applications without modification.
