About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX35-30S
The AirTAC SAIJ32X35-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 5-35 mm by trimming up to 30 mm from the 35 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod for improved corrosion resistance and uses a PT tapered port thread.
This adjustable-stroke design allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet works directly with AirTAC CMSE reed and DMSE electronic solid-state switches. 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 SAIJ32AX35-30S Is Used
Machine Setup Tuning
Dial in the exact 5-35 mm end position during machine commissioning without machining custom spacers or swapping cylinders.
Product Changeover
Quickly adapt the stroke end-stop for different product sizes on a packaging line by rotating the rear adjustment screw.
Precision Clamping
Fine-tune the clamping travel window to accommodate varying material thicknesses while maintaining 402 N of push force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX35-30S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa but require finer end-position control than a fixed SAI cylinder offers. If your application needs less force, step down to a 20 mm bore; if you need more thrust, step up to a 40 mm bore which provides 628 N at 0.5 MPa. Because the stroke is 35 mm, no external guide is strictly necessary for side loads, but the 12 mm rod diameter still requires standard alignment.
To match this ISO 15552 interchangeable cylinder, specify the 32 mm bore, 35 mm stroke, 30 mm adjustment range, PT port thread, and the -S magnet option. For load-holding without live air pressure, pair this cylinder with an external rod lock or select a SAIL or BSAI model instead, as the rear adjuster here is a stop, not a lock.
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 SAIJ32AX35-30S 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 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the 35 mm nominal stroke by up to 30 mm, creating a usable travel window of 5 to 35 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
