Description
1. ISO15552 (formerly ISO6431) Standard Pneumatic Cylinder
2. Piston features bidirectional Y-seal structure with cushioning function, offering extended service life and low friction resistance;
3. Aluminum barrel with cruciform reinforcement and black-anodized piston rod for enhanced corrosion resistance;
4. Precision machined cylinder surface ensures smooth operation;
5. Multiple cylinder specifications and mounting accessories available for flexible configurations.
Category: Standard Cylinders | Brand: AIRTAC | Series: SI125
Installation Guidelines:
Requires rigid mounting structure with alignment tolerance ≤0.2mm/m.
For horizontal installations exceeding 800mm stroke, support rails
must be used to prevent rod deflection. Maintain 1.5x bore diameter
clearance around cylinder for heat dissipation.

High-force industrial cylinder designed for heavy-duty linear motion applications. Features wear-resistant chromium plating on piston rod and precision honed cylinder tube. The dual adjustable cushioning system prevents impact damage at stroke ends. Optional magnetic piston version (SI125X1200STC-M9) available for position sensing.
Typical Applications:
- Steel mill slab pusher mechanisms
- Plastic injection molding machine ejectors
- Automotive press line material handling
- Shipbuilding fixture positioning systems
- Hydraulic system test bench load simulation
Installation Guidelines:
Requires rigid mounting structure with alignment tolerance ≤0.2mm/m.
For horizontal installations exceeding 800mm stroke, support rails
must be used to prevent rod deflection. Maintain 1.5x bore diameter
clearance around cylinder for heat dissipation.
Fluid Compatibility:
Use ISO VG32 hydraulic oil or equivalent for lubrication.
Air filtration must include 5μm particulate filter and
oil mist lubricator (except when using non-lubricated seals).
