Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-20
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X90-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 90mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-20
The AirTAC SAIJ200X90-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down by up to 20 mm. This creates a 70-90 mm usable stroke window, enabling precise end-position tuning at commissioning without swapping out the barrel or adding external stops. In the 200 mm bore class, it delivers massive thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa.
The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The robust 40 mm carbon steel rod and M36x2 thread provide high structural rigidity, though the 90 mm stroke is short enough that unsupported side-loading is less of a concern than on longer strokes. The rear adjuster acts purely as a travel stop 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 SAIJ200X90-20 Is Used
Product Changeover
Enables rapid mechanical adjustment of the end-stop when switching product sizes on a line, trimming the stroke by up to 20 mm without needing to physically swap out the entire actuator.
Machine Setup
Ideal for final commissioning of large automated machinery, letting technicians fine-tune the retract position to perfect machine timing without installing external stopper blocks.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-20 the Right Cylinder?
Choose this 200 mm bore when your application requires the maximum standard thrust class, as stepping down to a 160 mm bore reduces the 0.5 MPa push force to 10053 N. The adjustable 70-90 mm travel window is ideal for product changeovers on a line, allowing operators to dial in the exact end-stop mechanically rather than relying on fixed SAI cylinder lengths.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 90 mm nominal stroke, 20 mm adjustment range, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the SAIJ series omits FB, CA, CB, and CR mounts. Because the rear adjuster only sets the travel end and decelerates the load via air cushions, it cannot hold position without live air; for true load-holding, consider the SAIL or BSAI series.

- ✓ 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 SAIJ200X90-20 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that shortens the 90 mm nominal stroke by up to 20 mm, giving an effective travel range of 70 to 90 mm. It functions as a travel stop and deceleration point, meaning it will not hold a load without continuous live air pressure.
