A high-rigidity workhorse cylinder featuring precision honed tubing and hardened piston rods (chrome-plated, 25μm thickness). The SI40X300SN delivers smooth linear motion with ≤0.5mm cushion adjustment resolution. Anti-rotation design prevents rod spin during operation. Pre-lubricated for immediate use with ISO VG32 hydraulic oil.
- Press machine ejection systems (die casting applications)
- Automated palletizing arm actuators
- Plastic injection molding clamp mechanisms
- CNC machine tool door operators
- Textile machinery tension control systems
Installation guidelines:
Maintain ≤0.1mm/m alignment tolerance during mounting. Use flexible couplings when lateral forces exceed 15N.
For vertical mounting, install speed controller at lower port. Lubricate every 3,000km stroke distance.
