- CNC machine tool door interlocks
- Automated conveyor sorting gates
- Printing press paper feed systems
- Plastic injection molding ejectors
Installation guidelines:
Maintain 0.5mm minimum alignment tolerance during mounting. For vertical installations,
use rod-down orientation to prevent condensate accumulation. Lubricate through air supply
(ISO VG32 equivalent) if using non-lubricated version.
