About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-10
The AirTAC SAIJ32X550-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 540-550mm usable travel window, allowing you to dial back the nominal 550mm stroke by up to 10mm during commissioning. Delivering 402N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-10 Is Used
End-Position Tuning
Dial in the exact 540-550mm retract distance during machine setup to perfect product alignment without swapping physical cylinders.
Product Changeover
Quickly adjust the stroke stop by up to 10mm on a packaging line to accommodate slightly different carton lengths on the fly.
Light Assembly Push
Utilize the 402N push force at 0.5 MPa for delicate component seating, relying on the fine adjustment to prevent overtravel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-10 the Right Cylinder?
Choose this 32mm bore when your application requires precise end-position tuning without adding external stops. If your setup needs greater thrust, stepping up to the 40mm bore increases push force to 628N at 0.5 MPa. The rear adjuster acts strictly as a travel stop to set deceleration, not a lock; for load-holding without live air pressure, consider an external rod lock or the SAIL series.
Because this cylinder features a 550mm stroke, the 12mm rod should be guided externally to prevent excessive side-loading and premature seal wear. It maintains ISO 15552 mounting interface compatibility and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 Adjustable Cylinder SAIJ32 SAIJ32BX550-10 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective stroke from 550mm down to 540mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
