About the Airtac SAI200 Standard Cylinder SAI200AX25
The AirTAC SAI200X25 is a double-acting ISO 15552 profile cylinder engineered for extreme thrust in compact spaces. It generates 15708N of push force at 0.5 MPa, scaling up to 28274N at 0.9 MPa. The 25mm stroke is optimal for high-force clamping or short pressing operations. An extruded aluminum barrel eliminates protruding tie rods while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific unit features a SUS420J2 stainless steel piston rod for superior corrosion resistance and surface hardness. Fluid is filtered air, operating between -20 and +70 C. The barrel includes dual sensor grooves for CMSE or DMSE switches, though this configuration omits the internal magnet. For applications needing multi-position stopping, the related SAIJ adjustable-stroke variant offers extended versatility.

Where the Airtac SAI200 Standard Cylinder SAI200AX25 Is Used
Heavy-Duty Stamping
Provides the 15708N force at 0.5 MPa necessary for short-stroke metal forming and impact-free stamping tasks.
Industrial Clamping
Secures massive workpieces in machining centers using a 25mm stroke and SUS420J2 stainless rod for durability.
Press Fit Assembly
Drives large bearings into housings with precise 25mm travel, leveraging 28274N of force at 0.9 MPa.
Is the Airtac SAI200 Standard Cylinder SAI200AX25 the Right Cylinder?
Selecting this 200mm bore model is appropriate when 160mm bore capacity (14074N at 0.5 MPa) is insufficient for your peak loads. The 25mm stroke minimizes rod overhang, virtually eliminating side-load bending risks inherent to longer strokes. However, if your mechanism must maintain position or hold a load during air pressure loss, the standard SAI will drift; consider the SAIL air-released lock or BSAI bidirectional clamp-lock variant for fail-safe holding. Replacement mounting requires matching the 200mm ISO 15552 interface, G3/4 PT port, and appropriate TC or CA accessories.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI200 Standard Cylinder SAI200AX25 FAQ
At 0.5 MPa, it provides 15708N of push force and 15080N of pull force. At 0.9 MPa, the push force reaches 28274N.
Yes. It is a true ISO 15552 profile cylinder, making its mounting dimensions interchangeable with other ISO 15552 compliant cylinders, though you must ensure your setup uses a G3/4 port.
