About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-50
The AirTAC SAIJ200X290-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 290 mm stroke and a 50 mm adjustment range, you can dial back the effective travel to anywhere within a 240-290 mm window during commissioning.
The rear adjuster functions strictly as a mechanical stop to fine-tune the retract end position without adding external shock blocks. It is not a locking device; the cylinder relies on live air pressure to hold a load. For applications requiring fail-safe load holding without constant air, consider the SAIL or BSAI series instead. This unit features a carbon steel rod and PT tapered port threads.

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 SAIJ200X290-50 Is Used
Press Tonnage Tuning
Dial in the exact 240-290 mm travel window during heavy press setup to accommodate varying material thicknesses without swapping the entire cylinder.
Machine Changeover
Quickly adjust the retract end-stop position when switching production lines to different product sizes, saving hours of mechanical reconfiguration.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-50 the Right Cylinder?
The adjustable 240-290 mm travel window is ideal for product changeovers on heavy machinery where the exact end-of-stroke position varies slightly between fixtures. Because the total stroke exceeds 300 mm is not met here, standard internal guidance applies, but for heavy offset loads, an external guide is still recommended to protect the 40 mm carbon steel rod from excessive side-load wear. When replacing an ISO 15552 cylinder, match the 200 mm bore, 290 mm stroke, 50 mm adjuster, PT G3/4 port, and standard mounting interface. Note that SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options.
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 SAIJ200X290-50 FAQ
At the maximum 1.0 MPa pressure, it delivers 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 290 mm stroke by up to 50 mm, creating a usable travel window of 240-290 mm. It only sets the end position and does not lock the load without live air pressure.
