About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX30-30
The AirTAC SAIJ32X30-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 30mm travel by up to 30mm. This creates a highly versatile 0-30mm usable stroke window, giving you exact control over the end position during commissioning without needing to swap out the cylinder or bolt on external stops. It delivers 402N of push force at 0.5 MPa, making it suited for light-duty positioning tasks.
This model features a SUS420J2 stainless steel rod for enhanced durability against side loads and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and while no magnet is specified here, adding one enables compatibility with AirTAC CMSE reed and DMSE electronic sensors. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX30-30 Is Used
Position Calibration
Dial in the exact 0-30mm end position during machine commissioning to perfect sensor triggering and part placement.
Machine Changeover
Quickly adjust the travel end-stop on the line when switching between product sizes without replacing the cylinder.
Light Assembly
Utilize the 402N push force for delicate pressing or clamping tasks where over-travel must be restricted.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX30-30 the Right Cylinder?
Choose this 32mm bore when your application requires precise end-stop tuning within a very short travel distance. If you need slightly higher force, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. The rear adjuster screw acts purely as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series. Because the stroke is under 300mm, side-load risks are minimal, but an external guide is still recommended for heavy lateral loads. To match this ISO 15552 replacement exactly, verify the 30mm stroke, 30mm adjustment, PT port, and mounting interface.
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 SAIJ32AX30-30 FAQ
The rear adjuster screw lets you shorten the 30mm nominal stroke by up to 30mm, providing a usable travel window of 0-30mm. It acts as a mechanical stop to fine-tune the end position without changing the cylinder itself.
At an operating pressure of 0.5 MPa, the 32mm bore generates 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9 MPa.
