About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-30
The AirTAC SAIJ32X280-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 280 mm travel by up to 30 mm for a precise 250-280 mm usable window. It delivers 402 N of push force at 0.5 MPa, making it well-suited for compact automation tasks requiring exact end-position tuning.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-30 Is Used
End-Stop Calibration
Fine-tune the retract position within the 250-280 mm window during machine setup without changing the cylinder or adding external mechanical stops.
Product Changeover
Quickly adjust the stroke by up to 30 mm on packaging lines when switching to a different product size, minimizing downtime.
Light Assembly Positioning
Leverage the 402 N push force at 0.5 MPa to position light components accurately, dialing in the exact end point for delicate operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-30 the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with on-the-fly end-position tuning during commissioning or product changeovers, avoiding the need to swap cylinders or bolt on external stops. If your application requires less force, dropping to a smaller bore changes the footprint; if you need significantly more thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa.
Because the 280 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to prevent excessive side-loading on the 12 mm rod. To match this exact ISO 15552 replacement, specify: 32 mm bore, 280 mm stroke, 30 mm adjustment, PT G1/8 port, SUS420J2 rod, and no magnet. Note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits 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 SAIJ32AX280-30 FAQ
The rear adjuster screw lets you shorten the effective travel by up to 30 mm, providing a usable stroke window of 250-280 mm. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
