High-torque long-stroke pneumatic cylinder designed for heavy-duty industrial automation. Features precision-machined aluminum barrel with anti-corrosion treatment and double-sealed piston rod for harsh environments. The SH variant includes magnetic piston for position sensing compatibility. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Automotive production line clamping fixtures
- Steel coil handling systems
- Injection molding machine ejectors
- Paper mill roller positioning
- Warehouse vertical lift actuators
Installation note:
Requires rigid mounting surface with flatness ≤0.1mm/m. For vertical installations,
use rod-down orientation to prevent piston seal wear. Lubricate through air supply
(40μm filtered oil mist recommended).
Critical parameters:
Maximum side load 350N at mid-stroke. Avoid continuous operation above 0.8MPa
to prevent premature seal failure. Stroke tolerance ±2mm due to thermal expansion.
