About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-20S
The AirTAC SAIJ200X90-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 90 mm nominal stroke that can be dialed back by up to 20 mm, providing a usable travel window of 70-90 mm for precise end-position tuning during commissioning. In the 200 mm bore class, it delivers substantial thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
This variant includes a magnet for position sensing and uses a carbon steel rod with an M36x2 thread. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches exactly where needed. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

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 SAIJ200X90-20S Is Used
Heavy Press Tuning
Dial in the exact 70-90 mm pressing depth during machine setup to accommodate different material thicknesses without changing the physical cylinder setup.
Product Changeover
Quickly adjust the retract end-stop on a production line when switching between product sizes, saving downtime on the factory floor.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-20S the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires massive force—up to 15708 N at 0.5 MPa—and on-the-fly stroke trimming. The adjustable 70-90 mm window is ideal for product changeovers, letting you fine-tune the retract position without swapping cylinders or adding external stops. For a direct ISO 15552 replacement, match the 200 mm bore, 90 mm stroke, 20 mm adjustment, PT tapered port thread, and the -S magnet requirement.
Because the stroke is relatively short at 90 mm, side-load risks are minimized compared to longer strokes, but the heavy loads this bore handles still require robust external guiding. Remember that the rear screw is a travel stop, not a locking device; if the machine loses air, the cylinder will not hold its position. For true load-holding without live pressure, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock.
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 SAIJ200X90-20S FAQ
At the maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the 90 mm nominal stroke by up to 20 mm, creating a usable travel window of 70-90 mm. This stopper fine-tunes the end position at commissioning but does not lock the load without continuous air pressure.
