Professional-grade pneumatic cylinder engineered for construction equipment applications. Features triple sealing system with wiper, primary seal, and buffer seal for extreme environments. The oversized rod diameter (20mm) and thick-walled tube ensure structural integrity under lateral loads. Integrated shock absorption reduces peak impact forces by 40% compared to standard cylinders.
- Excavator bucket control mechanisms
- Concrete pump truck boom actuators
- Pile driver impact dampening systems
- Crane outrigger positioning
- Rock drill feed mechanisms
Installation guidance:
Use M6×12mm mounting screws (Grade 8.8 or higher) with Loctite 243 threadlocker.
Maintain 0.5-1mm clearance between rod end and load during alignment.
Lubricate with ISO VG32 hydraulic oil during assembly.
Critical note:
Requires 5μm filtration for particulate control.
Avoid continuous side load exceeding 150N.
Perform seal replacement every 500,000 cycles in high-vibration environments.
