About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-20S
The AirTAC SAIJ200X270-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 250 to 270 mm. The extruded aluminum barrel includes sensor grooves on both sides to accommodate CMSE reed and DMSE electronic switches.
This variant features a carbon steel piston rod with an M36x2 thread and PT tapered ports. The rear adjuster acts strictly as a mechanical stop to fine-tune the retract end position during commissioning without requiring external stops. It is important to note that this adjuster does not lock or hold the load without live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ200X270-20S Is Used
Heavy Press Tuning
Dial in the exact 250 to 270 mm end-stop during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover
Quickly adjust the retract position on a conveyor divert arm when switching between different large-format product sizes on the line.
Machine Setup
Fine-tune the end-of-stroke position during initial machine assembly to perfectly align heavy tooling without adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-20S the Right Cylinder?
The adjustable stroke is chosen over a fixed SAI cylinder when you need precise end-position tuning during machine setup or product changeover. For load-holding without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL or BSAI model instead.
Because the 270 mm stroke is substantial, ensure adequate external guiding to prevent excessive side loading on the M36x2 rod. To achieve a true ISO 15552 replacement match, verify the 200 mm bore, 270 mm stroke, 20 mm adjustment, PT port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ200X270-20S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 250 to 270 mm. This mechanical stop fine-tunes the end position but does not lock the load without live air pressure.
