High-power industrial cylinder designed for heavy-duty applications requiring precise stroke adjustment. Features triple sealing system with integrated wiper ring for contamination resistance. The hardened steel construction withstands side loads up to 15% of maximum thrust capacity. Requires 40μm filtered air with ISO VG32 lubricator oil (optional oil-free operation available).
- Metal stamping press ejection systems
- Injection molding machine clamp mechanisms
- Automotive assembly line positioning
- Foundry equipment for mold handling
- Heavy material compaction devices
Operational guidance:
Maintain 0.3-1.0MPa lubrication pressure during initial 50km stroke.
For vertical installations, use rod-down orientation with <500mm/s speed.
Stroke adjustment requires 6mm hex key (not included).
