About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-30S
The AirTAC SAIJ32X45-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a 402N push force at 0.5 MPa and features a 12mm piston rod with an M10x1.25 thread. By turning the rear stopper screw, you can trim the nominal 45mm stroke back by up to 30mm, creating a precise 15-45mm usable travel window for commissioning without swapping hardware.
This compact 32mm bore unit includes a magnet for CMSE reed and DMSE electronic sensors, which seat directly into the dual-side extruded barrel grooves. The rod is manufactured from SUS420J2 stainless steel (option A) for enhanced durability, and the body uses PT tapered port threading. It supports speeds of 30-800 mm/s and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-30S Is Used
Machine Changeover
Dial in the 15-45mm travel window during product size transitions without replacing the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract stroke endpoint at commissioning to perfectly strike or press a component within a compact 32mm bore footprint.
Sensor Integration
Utilize the integrated magnet with DMSE electronic or CMSE reed switches in the standard barrel grooves for precise position feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-30S the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your application requires exact end-position tuning rather than a fixed 45mm stroke. If your process needs less force, stepping down is not an option from this size, but if you require higher thrust, a 40mm bore provides 628N at 0.5 MPa. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding, select an SAIL or BSAI cylinder. This SAIJ32X45-30-S is dimensionally interchangeable per ISO 15552 and is configured with a PT port, SUS420J2 rod, and a -S magnet.

- ✓ 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 SAIJ32AX45-30S FAQ
At 0.5 MPa, this 32mm bore double-acting cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 45mm stroke by up to 30mm. This creates a 15-45mm usable travel window, enabling fine-tuning of the end position without changing the cylinder.
