About the Airtac SAI200 Standard Cylinder SAI200AX185S
The AirTAC SAI200X185-S is a double-acting ISO 15552 profile cylinder offering massive thrust, pushing with 21991 N of force at 0.7 MPa. This 185 mm stroke is ideal for heavy-duty press operations and high-tonnage clamping where extreme power is required.
Configured with an SUS420J2 stainless steel rod (option A) and a magnet for position sensing, it integrates seamlessly with CMSE and DMSE switches via the dual-side sensor grooves on its extruded aluminum barrel. The ports feature PT tapered threading, and adjustable air cushions at both ends protect against end-of-stroke impact.

Where the Airtac SAI200 Standard Cylinder SAI200AX185S Is Used
Heavy Metal Forming
Provides the immense tonnage needed to bend, stamp, and form thick sheet metal panels in automotive production lines.
Large Assembly Presses
Exerts consistent 21991 N clamping pressure at 0.7 MPa to hold oversized structural frames securely during robotic welding.
Pallet Handling
Drives robust lifting and positioning mechanisms for heavy-duty industrial pallets in high-capacity automated distribution centers.
Is the Airtac SAI200 Standard Cylinder SAI200AX185S the Right Cylinder?
Select this 200 mm bore when a 160 mm cylinder (providing 14074 N push at 0.5 MPa) cannot generate sufficient force for your heavy loads. Because this stroke is under 300 mm, side-load bending on the rod bearing is minimal, though external guides are recommended if absorbing heavy lateral moments.
If your machinery requires the load to stay fixed during a total air pressure loss, remember that the standard SAI piston will drift. For fail-safe holding, specify an SAIL pneumatic lock or a BSAI bidirectional clamp-lock variant. This unit drops directly into any ISO 15552 mounting interface using PT port connections and standard TC trunnion 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.
