A heavy-duty industrial cylinder featuring corrosion-resistant construction and precision honed tube. The SI125 series delivers exceptional load capacity with 0.1mm piston rod concentricity tolerance. Built-in magnet version available (SI125MX500S) for position sensing. Requires ISO VG32 hydraulic oil lubrication if used in high-cycle applications (>1 million cycles).
- Automotive production line clamping fixtures
- Steel coil handling equipment actuators
- Plastic injection molding machine ejectors
- Warehouse automated stacking systems
- Hydraulic press auxiliary positioning
Installation note:
For vertical mounting exceeding 45° angle, use rod-down orientation and install
a speed controller to prevent piston free-fall. Maintain 0.3mm minimum alignment
tolerance during mounting.
