A heavy-duty industrial cylinder featuring precision honed tubing and corrosion-resistant construction. The SAI63AX250S combines high thrust force (1,960N at 0.63MPa) with smooth motion control through dual adjustable buffers. Designed for 50,000km service life under standard conditions. Includes magnetic piston for sensor mounting (optional reed switch kits available).
- Automated production line material handling
- Press machine clamping mechanisms
- Automotive welding fixture positioning
- Packaging equipment door actuators
- Plastic injection molding ejector systems
Installation tip:
Maintain 0.1mm minimum alignment tolerance during mounting. Use flexible couplings for rod connections.
For vertical installations, add external guide mechanisms if side load exceeds 30N. Lubricate every 3,000km
of operation with ISO VG32 hydraulic oil.
