About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-30S
The AirTAC SAIJ32X750-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 402N push force at 0.5 MPa and uses a 12mm SUS420J2 stainless steel piston rod with an M10x1.25 thread. The built-in magnet supports CMSE reed and DMSE electronic sensors for exact position detection.
This model has a 750mm nominal stroke that can be dialed back by up to 30mm, creating a 720-750mm usable travel window for precise end-position tuning. The adjuster acts as a travel stop to set the retract end, but it is not a lock and will not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-30S Is Used
Machine Setup Tuning
Dial in the exact 720-750mm retract position during initial machine commissioning without machining external stop blocks.
Product Changeover
Quickly adjust the end-stop by up to 30mm on a packaging line when handling slightly different box sizes.
Variable End Stops
Use the rear adjuster screw to set precise end-of-stroke limits for delicate picking operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-30S the Right Cylinder?
Choose this adjustable-stroke model when you need to fine-tune the retract end-position during commissioning or product changeover without swapping the cylinder or adding external stops. If your application requires higher force, stepping up to the 40mm bore provides 628N at 0.5 MPa. For load-holding without live air, consider the SAIL or BSAI series instead of relying on this adjuster.
This SAIJ32X750-30-S is dimensionally interchangeable with ISO 15552 cylinders. It features PT tapered ports sized G1/8, a 27mm cushion, and a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 750mm, the 12mm rod needs an external guide to prevent excessive side-load and binding.
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 SAIJ32AX750-30S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
The rear adjuster screw lets you shorten the 750mm nominal stroke by up to 30mm, giving a usable travel window of 720-750mm. This allows fine-tuning of the retract end-position without replacing the cylinder.
