High-load industrial cylinder featuring precision honed tubing and triple-seal reinforcement. The SI125AX55S delivers 12% greater thrust efficiency compared to ISO 6432 equivalents, with integrated magnetic field for sensor compatibility. Optimized for heavy-duty cycling (≥1 million cycles @0.5MPa). Requires ISO VG32 hydraulic oil mist lubrication in continuous operation.
- Press machine ejection systems
- Automotive welding fixture positioning
- Bulk material gate control in mining
- Plastic injection molding machine clamping
- Steel coil handling equipment
Installation note:
Allow 15mm lateral clearance for thermal expansion. Use M12×1.5 mounting bolts (Grade 8.8 or higher).
For vertical mounting, install exhaust mist lubricator upstream. Avoid side-load exceeding 15% of max thrust.
