About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-50
The AirTAC SAIJ32X290-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 240 and 290 mm. The barrel is machined from extruded aluminum and includes sensor grooves on both sides for flexible switch placement.
This specific configuration incorporates a SUS304 stainless steel piston rod for enhanced corrosion resistance and utilizes PT tapered port threads. The integrated rear adjuster acts purely as a mechanical stop to dial in the exact end position during commissioning; it does not lock the load in place without continuous air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32BX290-50 Is Used
Machine Changeover
Dial in the 240-290 mm travel window rapidly when switching a packaging line to a different carton size, using the rear stopper instead of changing cylinders.
End-Position Tuning
Fine-tune the exact retract distance during initial commissioning to perfect a delicate pick-and-place motion without adding external mechanical stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-50 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke model when an application requires precise end-position tuning during setup or product changeover, avoiding the need to physically swap cylinders or bolt on external stops. If your process demands greater thrust, stepping up to the 40 mm bore SAIJ variant increases the 0.5 MPa push force to 628 N. Conversely, if you need to hold a load securely without live air pressure, this cylinder is not a lock; you should consider the SAIL or BSAI series instead.
Because the 290 mm stroke exceeds the 300 mm threshold, an external guide is recommended to prevent excessive side-loading on the piston rod. For a true ISO 15552 replacement, verify the 32 mm bore, 290 mm stroke, 50 mm adjustment range, PT port threads, and the required mounting style. SAIJ supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX290-50 FAQ
If you increase the pressure to 0.7 MPa, the push force rises to 563 N.
The rear adjuster screw lets you mechanically shorten the effective travel from 290 mm down to 240 mm. It functions as a hard stop for end-position tuning and does not hold the load without live air pressure.
