About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-40
The AirTAC SAIJ200X400-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 360-400 mm. Built with a robust 40 mm carbon steel rod and a PT G3/4 port, it delivers massive thrust up to 28274 N at 0.9 MPa. This makes it ideal for heavy-duty positioning tasks requiring exact end-stop tuning.
The external adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device, so live air pressure is required to hold the load. For true fail-safe load holding, consider the SAIL or BSAI series instead. This cylinder supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-40 Is Used
Heavy Press Tuning
Dial in the exact 360-400 mm stroke end-position during heavy press commissioning without swapping cylinders or adding external stop blocks.
Product Changeover
Adjust the retract distance on the fly to accommodate different large product sizes on the same high-force assembly line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-40 the Right Cylinder?
Choose this 200 mm bore when the 160 mm class (18095 N at 0.9 MPa) is insufficient for your heavy loads. The 40 mm adjustment range is perfect for product changeovers, letting you dial in the exact 360-400 mm travel without swapping the cylinder. If you need fixed travel without an adjuster, the standard SAI series is the alternative. Because the stroke is 400 mm, the long unsupported rod requires an external guide to prevent excessive side-loading and premature seal wear. Ensure your ISO 15552 replacement matches the 200 mm bore, 400 mm stroke, PT G3/4 port, and chosen mounting hardware.
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 SAIJ200 Adjustable Cylinder SAIJ200X400-40 FAQ
It reaches a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 400 mm stroke by up to 40 mm, creating a usable travel window of 360-400 mm. It functions as a mechanical stop for end-position tuning, not a load-holding lock.
