High-stroke industrial cylinder with corrosion-resistant construction, featuring precision honed inner tube for smooth operation. Designed for heavy-duty cycles (up to 5 million strokes at 0.5MPa). Includes magnetic sensor slots (not pre-installed) for position feedback. Requires 5μm filtered air and ISO VG32 hydraulic oil lubrication.
- Automated assembly line material handling
- Plastic injection molding ejector systems
- Textile machinery tension control
- Automotive welding fixture positioning
- Long-stroke packaging equipment actuators
Installation guidelines:
Align cylinder axis with load center. For vertical mounting exceeding 30° angle,
use rod-end support brackets. Lubricate through air port weekly in high-cycling
applications (＞500 cycles/hour). Adjust cushion screws gradually - overtightening
may cause piston rebound.
