The SUD40X250 features twin piston rods for enhanced moment resistance and positional stability in dynamic applications. Its symmetrical design minimizes lateral deflection during high-speed operations. The cylinder incorporates wear-compensating seals and an anti-rotation mechanism for precise linear motion. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
