About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-100S
The AirTAC SAIJ32X750-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 750 mm travel that can be fine-tuned backward by up to 100 mm, yielding a usable 650-750 mm end-position window. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant uses a SUS420J2 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel keeps the footprint dimensionally interchangeable with ISO 15552 cylinders, and the PT tapered port threads ensure a tight pneumatic seal.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-100S Is Used
Product Changeover
Dial the rear adjuster to shift the 650-750 mm travel window quickly when running a new package size on a packaging line.
End-Stop Tuning
Fine-tune the final retract position during machine setup without adding external stopper blocks or changing the cylinder.
Lightweight Routing
Handle 402 N push loads at 0.5 MPa to actuate lightweight conveyor routing gates or diverter arms over long travels.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-100S the Right Cylinder?
Choose this 32 mm bore when 402 N push force at 0.5 MPa is sufficient, stepping down from a 40 mm bore (628 N) to save space and air volume. The 100 mm adjustment window is ideal for dialing in exact end stops during machine commissioning or product changeover without swapping the cylinder. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ rear adjuster is a travel stop, not a lock.
With a 750 mm stroke, the 12 mm rod and M10x1.25 thread face leverage and side-load risks; an external guide is recommended to prevent binding. To replace this cylinder, match the 32 mm bore, 750 mm stroke, 100 mm adjuster, PT G1/8 port, and the -S magnet option. Mounting is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32AX750-100S FAQ
The rear adjuster screw acts as an external stopper that can shorten the effective stroke by up to 100 mm. This gives the 750 mm nominal stroke a usable travel window of 650-750 mm, allowing precise end-position tuning during commissioning. The adjuster only sets the travel end and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ32X750-100-S provides 402 N of push force and 345 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
