About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-10S
The AirTAC SAIJ32X250-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 240 to 250 mm, allowing you to dial back the nominal 250 mm stroke by up to 10 mm. Delivering 402 N of push force at 0.5 MPa, it uses a PT tapered port and a SUS420J2 stainless steel rod for improved corrosion resistance.
Because it includes a magnet (-S), this model directly supports AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-side barrel grooves. The rear adjuster functions strictly as a mechanical stop for end-position tuning, meaning it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-10S Is Used
Machine Changeover
Dial in the 240-250 mm travel window during product size changes without physically swapping the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke end during commissioning to compensate for mechanical tolerance or sensor placement variations.
Conveyor Diverter
Adjust the retract distance on the fly to handle varying package sizes on a single conveyor line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-10S the Right Cylinder?
Choose this 32 mm bore if your application requires precise end-position tuning during commissioning without adding external stops. If you need higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The 12 mm rod and M10x1.25 thread handle moderate side loads, but because this is a 250 mm stroke, you should use an external guide for heavy or off-center loads.
The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552. To match this exact configuration, select a 32 mm bore, 250 mm stroke, 10 mm adjustment, PT ports, SUS420J2 rod, and an -S magnet.
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 SAIJ32AX250-10S 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 the maximum 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 250 mm down to 240 mm. It is a travel stop only, not a lock, and the cylinder requires live air to hold position.
