The SI125AX90 industrial cylinder features a reinforced piston rod (chrome-plated steel) and anti-rotation design for heavy-duty applications. Its buffering system reduces end-impact noise to <75 dB(A) and extends service life to over 5,000 km travel distance. Compatible with all ISO 15552 mounting accessories and position sensors.
- Press machine ejection systems (300-500kN force output)
- Automotive welding fixture clamping mechanisms
- Plastic injection molding machine core pulling
- Heavy conveyor gate control in mining operations
- Steel coil handling equipment in rolling mills
Installation guidelines:
Lubricate with ISO VG32 hydraulic oil before initial use.
Maintain 0.3-0.6mm alignment tolerance during mounting.
For vertical installations, use M12 anti-vibration brackets (sold separately).
Critical note:
Requires 5μm filtration + automatic drain for optimal performance.
Avoid side-load exceeding 15% of maximum thrust.
Re-lubricate every 500km operation in high-cycle applications.
