About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-100
The AirTAC SAIJ32X260-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 260 mm stroke that can be dialed back by up to 100 mm, creating a highly flexible 160-260 mm usable travel window for product changeovers. In the 32 mm bore class, it generates 402 N of push force and 345 N of pull force at 0.5 MPa.
This unit is configured with an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic sensors if position feedback is later required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-100 Is Used
Machine Changeovers
Quickly dial in the 160-260 mm stroke window during product size changes without swapping out the entire actuator.
End-Stop Calibration
Fine-tune the retract position during commissioning to achieve precise mechanical alignment without adding external stoppers.
Variable Diverter Arms
Adjust the stroke length on pneumatic sorting arms to accommodate different package sizes on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-100 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of thrust at 0.5 MPa but demands variable end-stop positioning. If your setup requires significantly more force, stepping up to the 40 mm bore yields 628 N of push force. The SAIJ32X260-100 is selected over a fixed SAI cylinder when you need to fine-tune the retract position at commissioning without machining external stops. To replace an ISO 15552 cylinder, match the 32 mm bore, 260 mm stroke, PT port thread, and the required mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Because this model features a 260 mm stroke, the 12 mm rod should be adequately supported by an external guide to prevent excessive side-loading and premature seal wear. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ32AX260-100 FAQ
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.
The rear adjusting screw allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 160 to 260 mm, letting you set the exact end position without replacing the cylinder.
