About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-75S
The AirTAC SAIJ32X800-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 800 mm nominal travel by up to 75 mm for a precise 725-800 mm usable window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet for CMSE and DMSE sensors.
This model uses a G1/8 port and relies on an extruded aluminum barrel with sensor grooves on both sides. The rear stopper acts purely as a travel end-setter for product changeovers, not a load lock, meaning live air is required to maintain position against forces.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-75S Is Used
Variable Length Stops
Dial in the exact 725 to 800 mm retract distance on packaging lines to accommodate different carton lengths without adding external hard stops.
Machine Changeover
Quickly fine-tune the end-of-stroke position during product format changes, saving commissioning time on long-travel handling axes.
Extended Reach Actuators
Utilize the full 800 mm travel for transferring components between distant workstations, adjusting the final position by up to 75 mm as needed.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-75S the Right Cylinder?
Choose this 32 mm bore when an application requires a long 800 mm stroke but demands exact end-position tuning without swapping cylinders, offering 402 N push force at 0.5 MPa. If your setup needs less travel, stepping down to a 40 mm bore increases force to 628 N. For this 800 mm stroke, an external guide is strongly recommended to prevent excessive side-loading on the 12 mm rod.
To match this ISO 15552 interchangeable cylinder, confirm the 800 mm nominal stroke, 75 mm adjustment range, PT tapered port threads, and the -S magnet option. Because the rear adjuster only trims the retract end and is not a locking device, use an external rod lock or a SAIL cylinder if the load must be held without continuous air pressure.
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 SAIJ32AX800-75S 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 screw allows you to shorten the 800 mm nominal stroke by up to 75 mm, creating a 725-800 mm travel window. This stopper only sets the end position and does not lock the load without live air pressure.
