The SI40BX300SH features a square-profile aluminum body with reinforced mounting points, designed for high-rigidity applications requiring precise linear motion. Its optimized air cushion system reduces end-impact noise by 30% compared to previous models. The hard chrome rod with triple-layer sealing ensures >3,000km service life under ISO 1,000,000 cycle test conditions.
- High-speed packaging machinery (e.g., carton sealing, labeling systems)
- Automated assembly line clamping fixtures
- Plastic injection molding machine ejectors
- Automotive welding jig positioning
- Food processing conveyor gate controls
Installation tips:
Align cylinder axis within ±0.5° of load path. For vertical mounting,
use anti-drop locking nuts on piston rod threads. Lubricate with ISO VG32
hydraulic oil if using non-lube configuration exceeds 100 cycles/minute.
Critical note:
Avoid side-load exceeding 50N. When stroke exceeds 200mm,
mandatory use of guide mechanism per ISO 15552 stability requirements.
