About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-30S
The AirTAC SAIJ32X240-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 210-240 mm usable travel window. It generates 563 N of push force at 0.7 MPa, making it suitable for light-duty precision tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This variant uses a SUS420J2 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a travel stop to fine-tune the retract position without adding external stops, but it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-30S Is Used
Machine Setup Tuning
Dial in the exact 210 to 240 mm retract end-stop during initial commissioning without swapping out physical cylinder hardware.
Product Changeover
Quickly adapt the travel distance on a packaging line when product sizes change, using the 30 mm rear adjustment screw.
Light-Duty Positioning
Move small jigs or fixtures with 563 N of force while relying on the external stop to set the final precise rest position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-30S the Right Cylinder?
Choose this 32 mm bore cylinder when you need 563 N of push force at 0.7 MPa and a highly adjustable end position during commissioning. If your application requires less force, stepping down is not an option below 32 mm, but stepping up to a 40 mm bore yields 879 N of push force. The PT tapered G1/8 port and SUS420J2 rod material are standard here. For load-holding without live air, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop.
Because the 240 mm stroke exceeds 300 mm only slightly, side-load risks are minimal but still require external guiding for heavy loads. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB and CA styles.
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 SAIJ32AX240-30S FAQ
At an operating pressure of 0.7 MPa, this 32 mm bore cylinder provides 563 N of push force and 345 N of pull force at 0.5 MPa.
The rear adjuster screw lets you shorten the nominal 240 mm stroke by up to 30 mm, creating a usable travel window of 210 to 240 mm. It functions as a stop, not a lock.
