A mid-sized industrial cylinder combining precision engineering with heavy-duty performance. Features dual cushioning for smooth stroke termination and corrosion-resistant construction. The square profile design enables multiple mounting configurations while maintaining compact dimensions. Requires 40μm filtered air and ISO VG32 hydraulic oil lubrication for optimal seal life.
- Automated assembly line clamping mechanisms
- Plastic injection molding machine ejectors
- CNC machine tool door actuators
- Material handling conveyor diverters
- Textile machinery tensioning systems
Installation note:
Allow 3-5mm axial clearance for thermal expansion during operation.
Use only counterbore-style rod end fittings to prevent thread damage.
Lubricate through air supply (oil mist) at 1 drop/cycle for dry systems.
