About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-100
The AirTAC SAIJ32X220-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a generous 120-220 mm usable travel window, allowing you to dial back the 220 mm nominal stroke by up to 100 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The piston rod is built from SUS304 stainless steel (code B) for corrosion resistance, and the extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This adjustable model uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The rear adjuster screw acts purely as a mechanical stop to fine-tune the end position and aid deceleration; it does not hold the load without live air pressure. For true load-holding, consider the SAIL or BSAI series. Standard PT tapered ports and a 12 mm rod thread handle the pneumatic supply and side-load transmission.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-100 Is Used
Product Changeover
Dial in the exact retract distance for different part lengths on a single conveyor line, using the 100 mm adjustment window to switch sizes without changing hardware.
Commissioning Fine-Tune
Trim the nominal 220 mm stroke back to the exact required position during machine setup, preventing hard mechanical crashes and optimizing cycle timing.
Light-Duty Positioning
Leverage the 402 N push force at 0.5 MPa to move small jigs or fixtures into place, relying on the SUS304 rod for durable, corrosion-resistant operation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-100 the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires a variable end-stop rather than a fixed 220 mm stroke. The 100 mm adjustment range is perfect for machine setups that process varying product sizes on a single line, letting operators change the retract distance without swapping cylinders or adding external stops. If your process demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa, whereas lighter duties can drop to a smaller unit.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 220 mm stroke, 100 mm adjustment range, PT port thread, and the SUS304 rod material. Note that because the stroke is 220 mm, the 12 mm rod and M10x1.25 thread require careful alignment; long unsupported strokes still need an external guide to prevent excessive side-loading. This unit ships without a magnet, so position sensing requires external stops or a different configuration.

- ✓ 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 SAIJ32BX220-100 FAQ
The rear adjuster screw lets you shorten the effective travel from the 220 mm nominal stroke down to as little as 120 mm. This creates a 120-220 mm usable window, acting as a mechanical stop to set the retract end position precisely without needing external stops.
At a 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. If you increase pressure to 0.7 MPa, the push force rises to 563 N.
