Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 240mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-30
The AirTAC SAIJ32X240-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 210-240 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The piston rod uses SUS420J2 stainless steel, and the PT tapered port threads match the standard 32 mm bore G1/8 interface.
This cylinder allows fine end-position tuning at commissioning without adding external stops. The rear adjuster acts purely as a travel stop for the air cushion, meaning it will not hold a load without live air pressure. For load-holding needs, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-30 Is Used
End-Stop Tuning
Dial in the exact 210-240 mm travel distance during machine commissioning to perfect part ejection without swapping cylinders.
Product Changeover
Quickly adjust the retract end-position on packaging lines when handling slightly different product sizes.
Light Assembly
Apply 402 N of push force for precise light-duty pressing and component seating operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-30 the Right Cylinder?
Choose this 32 mm bore if your application requires around 402 N of push force at 0.5 MPa. Stepping down is not an option below 32 mm in this series, but stepping up to the 40 mm bore yields 628 N if your payload increases. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, replacing the need for a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 240 mm stroke, 30 mm adjustment range, PT port threads, and standard mounting interface. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Since this unit lacks a magnet, it cannot host CMSE or DMSE sensors.
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 SAIJ32AX240-30 FAQ
The rear adjuster screw lets you trim the effective stroke by up to 30 mm, providing a usable travel window of 210-240 mm. It acts as a mechanical stop for the cushion and does not lock the load without live air.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. The maximum force is 724 N at 0.9 MPa.
