High-precision industrial cylinder featuring chromium-plated piston rod and aluminum alloy barrel. The SI40X310S delivers 1,256N thrust at 0.7MPa pressure (theoretical value). Optimized for heavy-duty cycling with 5,000km rated service life under standard conditions. Features dual anti-rotation design for mounting stability.
- Automated material handling systems
- Plastic injection molding ejectors
- CNC machine tool clamping mechanisms
- Automotive assembly line positioning
- Packaging equipment pusher systems
Installation guidelines:
Maximum side load ≤15% of theoretical thrust. Lubricate through air port with ISO VG32 hydraulic oil
for initial operation. Requires 5-10μm filtered air supply. Allow 1.5× stroke length clearance
for full extension safety margin.
Maintenance alert:
Replace wiper seals every 500,000 cycles in high particulate environments.
Avoid angular misalignment exceeding ±2° during mounting.
