Heavy-duty pneumatic cylinder engineered for construction equipment applications, featuring enhanced corrosion resistance and impact tolerance. The double-cushion design minimizes end-stroke vibration, while the hardened piston rod withstands lateral forces common in excavator arms and loader linkages. Requires ISO VG32 hydraulic oil mist lubrication in high-cycle applications.
- Excavator bucket angle adjustment mechanisms
- Concrete pump truck boom positioning
- Bulldozer blade height control systems
- Crane outrigger stabilization deployment
- Drilling rig feed force regulation
Installation recommendation:
For vertical mounting applications exceeding 45° inclination,
install auxiliary guide mechanisms to prevent piston rod side-loading.
Use locknuts with 35-45 N·m torque specification during rod end assembly.
- Dehumidification required when operating below 0℃ to prevent icing
- Monthly lubrication cycle in high-dust environments (SAE 10W oil)
- Rod wiper replacement every 500,000 cycles in abrasive conditions
