About the Airtac SAI200 Standard Cylinder SAI200AX185
The AirTAC SAI200X185 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion tasks. It generates 15708 N of push force at 0.5 MPa and safely operates within a 0.15-1.0 MPa pressure range. This 185 mm stroke is a non-standard, made-to-order length designed for specific heavy-load strokes.
This model features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. While standard sensors require a magnet, you can easily integrate CMSE or DMSE switches into the dual-side sensor grooves on the extruded aluminum barrel if needed.

Where the Airtac SAI200 Standard Cylinder SAI200AX185 Is Used
Heavy Metal Stamping
Provides the robust 15708 N push force required to actuate large presses and form thick metal components securely.
Large Mold Handling
Moves substantial injection molds or tooling safely, utilizing the 185 mm stroke to index heavy assemblies into position.
Industrial Press Brakes
Delivers consistent clamping pressure for bending thick plate steel, relying on adjustable air cushions to absorb shock.
Is the Airtac SAI200 Standard Cylinder SAI200AX185 the Right Cylinder?
This 200 mm bore provides massive thrust; step down to a 160 mm bore if your application only requires 10053 N at 0.5 MPa. For this specific 185 mm stroke, side-load stress on the rod bearing is moderate, but always ensure the load is guided externally to prevent premature wear. Because this is a non-standard stroke, allow additional lead time for manufacturing.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders matching the 200 mm bore, 185 mm stroke, G3/4 port, and standard mounting accessories. Note that the adjustable air cushions only decelerate the piston at stroke ends; they do not hold a load. If pressure is lost, the rod drifts, so use the SAIL or BSAI variants for secure position holding.
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 SAI200AX185 FAQ
At 0.5 MPa, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It reaches a maximum theoretical force of 3204 kgf at 1.0 MPa.
No, the standard SAI cylinder drifts when air pressure is lost because the adjustable cushions only decelerate the piston, they do not lock it. For position holding without live pressure, use the SAIL (air-released lock) or BSAI (clamp-lock) variants.
