A heavy-duty industrial cylinder optimized for high-load linear motion applications. Features precision honed aluminum alloy tube with oxidation-resistant coating and wear-resistant guide rings. The dual adjustable cushions minimize end-impact noise while allowing 0-20mm cushion adjustment range through hex wrench.
- Automotive welding fixture clamping mechanisms
- Press machine ejection systems
- Palletizing robot end-effector actuators
- Injection molding machine core-pulling units
- Steel coil handling equipment
Installation protocol:
Lubricate via air line lubricator (ISO VG32 recommended).
Avoid side load exceeding 30N·m. For vertical mounting,
use rod-down orientation to prevent seal wear.
Allow 50mm clearance behind cushion screws for maintenance.
