About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-20
The AirTAC SAIJ32X125-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 20 mm. This creates a usable stroke window of 105 to 125 mm, enabling precise end-position tuning at commissioning without swapping out the physical cylinder.
This model incorporates a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and operates at speeds between 30 and 800 mm/s. The rear adjustment screw acts purely as a mechanical stop to set the retraction endpoint, meaning it cannot hold a load in place without continuous live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-20 Is Used
Machine Setup Calibration
Dial in the exact 105-125 mm retraction point during initial commissioning to perfectly align a 32 mm bore actuator without adding external stopper blocks.
Product Size Changeovers
Quickly adapt the stroke end-position by up to 20 mm on a packaging line when switching to a different product size, minimizing downtime.
Variable End-Stop Positioning
Provide fine-tuned mechanical stops for delicate pressing or clamping tasks where a fixed 125 mm stroke would apply too much travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-20 the Right Cylinder?
The adjustable stroke is highly beneficial for product changeovers or variable end-stops, offering flexibility that a fixed-stroke SAI cylinder cannot provide. For load-holding without live air, this cylinder is insufficient as the adjuster is only a stop, so you should explore an SAIL locking cylinder or an external pilot-operated check valve.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 125 mm nominal stroke, 20 mm adjustment range, PT port threads, and the specific mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Because this unit lacks the -S magnet suffix, it will not work with AirTAC CMSE or DMSE sensors.

- ✓ 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 SAIJ32AX125-20 FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the 125 mm nominal stroke by up to 20 mm, providing an effective travel window of 105 to 125 mm. This screw functions only as a travel stop and does not lock the load without live air pressure.
