About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-20S
The AirTAC SAIJ200X290-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 270-290 mm usable travel window, allowing you to dial back the 290 mm nominal stroke by up to 20 mm during commissioning.
This -S variant includes a magnet for position sensing and uses a carbon steel rod with a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjustment screw functions purely as a travel stop to set deceleration endpoints, not as a lock to 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 SAIJ200X290-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 270-290 mm end position during heavy press setup to accommodate varying material thicknesses without swapping cylinders.
Product Changeover Stops
Adjust the retract stop on a packaging line to handle different box sizes quickly, using the rear screw rather than bolting on new external stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-20S the Right Cylinder?
An adjustable stroke is chosen over a fixed-stroke SAI when you need variable end-stops for product changeovers or fine-tuning at machine setup without adding external physical stops. For load-holding without continuous air pressure, this cylinder is insufficient; you should consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 290 mm nominal stroke, 20 mm adjustment range, PT G3/4 port, and the -S magnet. Because the 290 mm stroke is substantial, the 40 mm rod diameter and M36x2 thread handle high side loads, but long unsupported strokes still require an external guide to prevent rod binding. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ200X290-20S FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 20 mm, creating a 270-290 mm usable window. It acts as a physical stop to set the end position and deceleration point, but it does not lock or hold the load without live air pressure.
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf of thrust.
