Heavy-wall cylinder specifically engineered for construction equipment applications. Features triple sealing system (rod seal, buffer seal, and wiper) with dust-resistant design. The reinforced end caps incorporate vibration-damping alloy inserts, making it suitable for mobile hydraulic/pneumatic hybrid systems. Requires 5μm filtered compressed air with ISO 8573-1:2010 class 4.4.3 air quality.
- Excavator bucket positioning mechanisms
- Concrete pump truck boom articulation
- Loader arm hydraulic assist systems
- Pile driver impact dampening
- Drilling rig feed force control
- Crane outrigger synchronization
Installation Note:
Requires torque-controlled mounting (22-25Nm for flange bolts). For vertical installations,
use rod-down orientation with moisture drain port facing downward. Maintain 0.5°-1°
alignment tolerance during system integration.
- Re-lubricate every 5,000km of rod travel (use ISO VG32 hydraulic oil)
- Inspect cushion seals every 2,000 operating hours
- Replace wiper seal annually in high-dust environments
