About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-10
The AirTAC SAIJ32X325-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 325 mm nominal stroke that can be dialed back by up to 10 mm, yielding a 315-325 mm usable travel window for precise end-position tuning. Delivering 402 N of push force at 0.5 MPa, it fits compact pneumatic setups requiring exact stop calibration.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to decelerate the end of stroke, not as a lock to hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-10 Is Used
End-Stop Calibration
Dial in the exact 315-325 mm travel window during machine commissioning to perfect end-position accuracy without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate minor product size variations on a production line.
Assembly Positioning
Use the fine stroke adjustment to precisely set the retraction point for delicate assembly operations requiring 402 N of force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-10 the Right Cylinder?
Choose this 32 mm bore when an application needs 402 N push force at 0.5 MPa alongside fine-tuned travel limits. The 10 mm rear adjuster allows you to set exact end positions during commissioning without adding external stops, unlike a fixed-stroke SAI cylinder. If your setup requires higher force, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. Because the 325 mm stroke is relatively long for a 32 mm rod, an external guide is recommended to prevent excessive side-loading.
When replacing an ISO 15552 cylinder, match the 325 mm stroke, 10 mm adjustment, PT G1/8 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface. This unit lacks a standard magnet, so position sensing requires adding the -S option. For load-holding without live air, consider the SAIL or BSAI series instead of relying on the rear stopper.
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 SAIJ32AX325-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm, creating a 315-325 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
