The SI40X15S features a compact profile with high moment resistance, achieving 30% better side load capacity than previous generations. Its dual-seal design combines NBR for static sealing and PU for dynamic sealing, enabling maintenance intervals up to 3,000km cumulative travel. The cylinder incorporates an anti-rotation mechanism in the piston rod for precise linear motion control.
