About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-30
The AirTAC SAIJ32X325-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position. It provides a usable travel window of 295 to 325 mm, making it highly effective for product changeovers without swapping hardware. The 32 mm bore generates 402 N of push force at 0.5 MPa, scaling up to 724 N at 0.9 MPa.
This unit features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Because it lacks a magnet, adding position switches requires specifying the -S option at order to utilize CMSE reed or DMSE electronic sensors.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-30 Is Used
Changeover Adjustment
Dial in the exact 295 to 325 mm end position during machine changeovers without adding external stopper blocks.
End-Position Trimming
Fine-tune the retract stroke by up to 30 mm at commissioning to perfect the seating of delicate parts.
Variable Product Sorting
Adjust the stroke on the fly to accommodate different package sizes on a pneumatic diverter arm.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-30 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-stop tuning within a 295-325 mm travel window, delivering 402 N push force at 0.5 MPa. If your setup demands less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 628 N at 0.5 MPa. The adjustable rear screw is strictly a travel stop for deceleration and positioning, not a lock; it will not hold a load without live air. For load-holding requirements, consider the SAIL or BSAI series, or use an external pilot-operated check valve.
Since the 325 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 rod thread have limited side-load capacity. Always guide the load externally to prevent rod binding. This SAIJ model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR configurations. It is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ32AX325-30 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, allowing you to shorten the effective travel from the nominal 325 mm down to 295 mm. It only sets the end position and does not lock the load without air pressure.
