About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X225-50S
The AirTAC SAIJ200X225-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It features a 200 mm bore and a 50 mm adjustment range, creating a usable travel window of 175-225 mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
Fitted with a PT tapered port thread and a robust 40 mm carbon steel rod with an M36x2 thread, this unit handles high side loads effectively. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet operates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. Variable air cushions at both ends manage deceleration, but note that the rear adjuster acts only as a travel stop, not a load-holding lock.

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 SAIJ200X225-50S Is Used
Heavy Press Tuning
Dial in the exact 175-225 mm end position for heavy pressing tasks without installing external physical stops.
Product Size Changeover
Quickly adapt the retract end-stop on a packaging line when switching between different large product dimensions.
Machine Commissioning
Fine-tune the final travel distance during initial machine setup to perfect timing and avoid mechanical collisions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X225-50S the Right Cylinder?
Selecting this 200 mm bore model is ideal when your application requires maximum thrust—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. An adjustable stroke is chosen over a fixed SAI cylinder when you need variable end stops for product-size changeovers on a line. Since the 225 mm stroke is under the 300 mm side-load threshold, external guides are less critical, though the 40 mm rod provides excellent resistance to deflection.
To match this ISO 15552 cylinder for a replacement, verify the 200 mm bore, 225 mm stroke, 50 mm adjustment range, PT port thread, and the -S magnet option. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If your process requires the load to be held without live air pressure, this cylinder will not suffice; consider an AirTAC SAIL or BSAI series instead.
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 SAIJ200X225-50S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 225 mm stroke by up to 50 mm, providing a usable travel window of 175-225 mm. This stopper only sets the end position and decelerates the load; it does not lock or hold the load without continuous air pressure.
