About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-30S
The AirTAC SAIJ32X250-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 220 to 250 mm. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This variant features an SUS420J2 stainless steel rod and a built-in magnet for position sensing. The PT tapered port ensures a tight pneumatic connection. The rear adjustment screw allows precise end-position tuning during commissioning without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-30S Is Used
Machine Setup Tuning
Dial in the exact retract end-position within the 220-250 mm window during commissioning without swapping out the entire cylinder.
Product Size Changeover
Quickly adjust the stroke length on packaging lines when handling different product sizes, using the 30 mm trim range to adapt the stop.
Light-Duty Positioning
Leverage the 402 N push force and CMSE/DMSE sensor compatibility for precise, light-load handling and end-of-stroke verification.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-30S the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient for your load. If your application requires greater force, stepping up to the 40 mm bore yields 628 N. An adjustable stroke is preferred over a fixed SAI cylinder when you need a variable end-stop for product changeovers. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. This model uses PT ports and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.
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 SAIJ32AX250-30S 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 lets you shorten the nominal 250 mm stroke by up to 30 mm, creating a usable travel window of 220 to 250 mm. It functions as a mechanical stop and does not lock the load without live air pressure.
