Heavy-wall cylinder specifically engineered for construction equipment applications, featuring reinforced rod bearings and anti-corrosion treatment. The double-sealed piston design maintains consistent force output (2,500N theoretical thrust @0.63MPa) even under side load conditions. Integrated wear rings prevent metal-to-metal contact during off-center operations.
- Excavator bucket control mechanisms
- Concrete pump truck outrigger systems
- Bulldozer blade adjustment actuators
- Crane boom locking devices
- Rock drilling equipment feed systems
Installation recommendation:
Mount with 0.1-0.3mm clearance between rod and guide to prevent binding.
Use locknuts with 25-30 N·m torque for rod-end connections.
Apply silicone-based grease every 500 operating hours in high-dust environments.
