Heavy-duty pneumatic cylinder engineered for construction equipment applications. Features enhanced structural integrity with 20% thicker tube walls compared to standard ISO cylinders, capable of withstanding shock loads up to 1.5x rated pressure. Includes anti-rotation guide slots and reinforced rod bearings for lateral force resistance. Requires ISO VG32 hydraulic oil lubrication when used in high-cycle applications (>500,000 cycles/year).
- Excavator bucket locking mechanisms
- Concrete pump truck valve actuators
- Crane outrigger position locks
- Drilling rig feed control systems
- Loader arm positioning cylinders
Installation note:
Use M8x1.25 mounting bolts with Loctite 243. Maintain 0.5-1mm alignment
tolerance during installation. For vertical mounting orientations,
install drip cups on rod end to prevent contamination ingress.
- Relubricate every 500km of cumulative rod movement
- Replace wiper seals every 2 million cycles
- Inspect rod concentricity quarterly in high-vibration environments
