High-load long-stroke pneumatic cylinder engineered for heavy-duty industrial applications. Features wear-resistant chromium-plated piston rod and double-seal structure for leak prevention. The oversized cushion design minimizes end-impact noise at full stroke. Requires ISO 8573-1 class 3 or cleaner compressed air.
- Automotive production line lifting mechanisms
- Steel coil handling in metal processing
- Large-format injection molding machine ejection
- Paper roll positioning systems
- Shipyard material transfer equipment
Installation note:
Requires rigid mounting structure with alignment tolerance ≤0.2mm/m.
For strokes >1500mm, install intermediate support brackets every 800mm.
Lubricate with ISO VG32 hydraulic oil if used without auto-lubricator.
Maximum side load capacity: 1,200N.
For vertical installations, use speed control valve to prevent free-fall.
Buffer adjustment requires 10-15 full-stroke cycles for optimal setting.
