- Packaging line product positioning gates
- Automated assembly station pushers
- Textile machine tension control systems
- 3-axis positioning in material handling
Installation note:
Lubricate with ISO VG32 hydraulic oil before initial use. For precise stroke adjustment,
loosen the lock nut and rotate the stopper (1mm per full rotation). Maintain 0.3-1 MPa
operating pressure for optimal seal performance. Avoid lateral loads exceeding 30N.
