About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-10
The AirTAC SAIJ32X280-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 270 to 280 mm, allowing you to dial back the nominal stroke by up to 10 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push thrust and 345 N of pull thrust at 0.5 MPa operating pressure.
This variant uses a SUS304 stainless steel rod (option B) for improved corrosion resistance and features PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts as a travel stop, not a clamp; it cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-10 Is Used
Machine Changeover
Dial in the exact 270 to 280 mm retract position when switching product sizes on a packaging line, avoiding physical cylinder swaps.
End-Stop Tuning
Use the 10 mm rear adjustment screw to fine-tune the final resting position of the 12 mm rod during initial equipment commissioning.
Sensor Integration
Mount CMSE reed or DMSE electronic switches directly into the dual-side barrel grooves for precise position feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-10 the Right Cylinder?
Choose this 32 mm bore if your application requires around 402 N push force at 0.5 MPa. If your setup needs greater thrust, stepping up to the 40 mm bore yields 628 N push force at the same pressure. Conversely, lighter duties can drop to smaller bores. The 10 mm adjustable end-stop is ideal for fine-tuning the retract position on machine changeover without swapping cylinders or adding external stops. Because the 280 mm stroke is relatively long for this bore, an external guide is recommended to prevent excessive side-loading on the 12 mm rod and M10x1.25 thread. For load-holding without continuous air, consider an AirTAC SAIL or BSAI cylinder instead. This unit is dimensionally interchangeable with ISO 15552 cylinders and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ32BX280-10 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The operational speed range is 30 to 800 mm/s.
The rear adjuster acts as a mechanical stop that shortens the effective travel. For this model, it creates a 270 to 280 mm usable stroke window, letting you trim the retract position without adding external stops.
