- Automotive assembly line clamping fixtures
- Paper processing equipment actuators
- Heavy-duty packaging machinery
Installation note:
Lubricate rod bearings with ISO VG32 hydraulic oil before initial operation.
For vertical mounting, install locknut (accessory code: LN-20) to prevent
piston rod rotation. Maintain 50mm clearance behind cylinder for full stroke extension.
