Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-100
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-100 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 SAIJ32AX240-100
The AirTAC SAIJ32X240-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 240 mm travel by up to 100 mm. This yields a highly flexible 140-240 mm usable window, enabling precise end-position tuning at commissioning without swapping out the entire unit. It delivers 402 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod for enhanced corrosion resistance.
The rear adjuster functions strictly as a travel stop for the retract end, meaning it does not lock or hold the load without continuous live air pressure. For load-holding applications without air, consider the SAIL or BSAI variants. This 32 mm bore model uses a PT tapered G1/8 port, includes variable air cushions at both ends, and operates at speeds of 30-800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-100 Is Used
Machine Changeover
Dial in the 140-240 mm retract window during product size changes without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the final retract position during commissioning to achieve exact alignment, compensating for mechanical tolerances in the fixture.
Variable Stops
Provide an adjustable physical stop for diverter arms or pushing mechanisms where the required travel distance varies between production runs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-100 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa but demands a variable retract end-stop for frequent product changeovers. If your setup requires significantly more force, stepping up to the 40 mm bore provides 628 N of push force. The SAIJ32X240-100 is selected over a fixed SAI cylinder when you need on-the-fly stroke trimming rather than a rigid 240 mm end position.
When matching this for an ISO 15552 replacement, verify the 32 mm bore, 240 mm stroke, 100 mm adjustment range, PT G1/8 port, and required mounting style. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the total stroke reaches 240 mm, the 12 mm rod should be adequately supported by an external guide to prevent excessive side-loading and premature seal wear. This variant lacks a magnet; adding a -S suffix enables CMSE reed or DMSE electronic sensors.

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 SAIJ32AX240-100 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 pressure, it can deliver up to 82 kgf.
The rear adjuster acts as a stopper that lets you shorten the effective stroke from the nominal 240 mm down to as little as 140 mm. It only sets the travel end and does not lock the load without live air pressure.
