Installation note:
Maintain 0.1-0.3mm alignment tolerance during mounting. For vertical installations exceeding 45° angle,
use rod-end support brackets (ASSU-125 recommended). Lubricate through air supply (ISO VG32 equivalent oil mist)
if non-lubricated operation is required.
Avoid side loads exceeding 200N. For pulsating loads or vibration environments,
install external shock absorbers. Magnetic switch cables must maintain 50mm clearance from high-voltage lines.
