High-force industrial cylinder designed for heavy-duty linear motion applications. Features corrosion-resistant construction with precision honed tube and wear-resistant seals. Optional magnetic piston version (SI125X80S-M9) available for position sensing. Requires filtered air with 40μm filtration (lubricated or non-lubricated operation).
- Automotive press line automation
- Injection molding machine ejectors
- Steel mill material handling systems
- Packaging machine compression units
- Foundry equipment actuators
Installation tip:
Align cylinder axis precisely with load path. For vertical mounting,
use auxiliary guide mechanisms when handling eccentric loads exceeding
15% of piston diameter. Lubricate through air supply (ISO VG32 recommended)
for extended seal life.
