A heavy-duty industrial cylinder designed for high-force linear motion applications. Features precision honed tubing and triple-lip rod seals for extended service life (>5,000km travel distance). The magnetic piston version (SI125X235SN-M9) enables position sensing compatibility. Requires ISO 8573-1:2010 Class 3-4-3 compressed air.
- Automotive press line material handling
- Steel mill roller positioning systems
- Injection molding machine ejectors
- Shipbuilding fixture clamping
- Hydraulic press assist systems
Installation guidelines:
Align cylinder axis within 0.2mm/m parallelism tolerance.
Use flexible couplings for rod-end connections.
Lubricate with ISO VG32 hydraulic oil if non-lubricated air is used.
Allow 50mm clearance behind rear flange for maintenance.
