About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-20
It features a robust 40mm carbon steel piston rod and a PT G3/4 port to ensure high flow rates for rapid actuation. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This model incorporates a rear mechanical stopper that allows you to fine-tune the effective stroke, creating a usable travel window of 270 to 290mm. The adjustment mechanism acts purely as a travel stop to set the retract end position accurately during commissioning. It is not a locking device; the cylinder relies on live air pressure to maintain load, and the air cushions at both ends only manage end-of-stroke deceleration.

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 SAIJ200X290-20 Is Used
Heavy Press Tuning
Dial in the exact 270-290mm retract position during heavy press commissioning to accommodate varying material thicknesses without external stopper hardware.
Product Changeover
Quickly adjust the end-stop distance on a packaging line when switching between different large-format product sizes, minimizing downtime.
Large Assembly Jigs
Provide massive 15708N clamping force at 0.5MPa for large structural assembly jigs while retaining the ability to fine-tune the final resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-20 the Right Cylinder?
The 20mm adjustable stroke range is highly beneficial for machine setups requiring precise end-position calibration without adding external stops or swapping out a fixed-stroke SAI cylinder. If your process demands true load holding without continuous air pressure, this standard cylinder will not suffice; you should instead consider the SAIL air-released lock or BSAI clamp-lock series.
When replacing an ISO 15552 cylinder, verify the 200mm bore, 290mm stroke, 20mm adjustment range, PT G3/4 tapered port, and the specific mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this unit lacks the -S magnet option, it cannot host CMSE reed or DMSE electronic sensors. Furthermore, with a 290mm stroke and a heavy 40mm rod, always utilize an external guide rail to prevent excessive side-loading and premature seal wear.
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 SAIJ200X290-20 FAQ
At the maximum operating pressure of 1.0MPa, it can deliver up to 3204kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 290mm stroke by up to 20mm, giving an effective travel window of 270 to 290mm. It only sets the end position and does not lock the load without live air pressure.
