About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-40S
The AirTAC SAIJ32X800-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 760-800 mm usable travel window. It delivers 402 N of push thrust at 0.5 MPa and uses a 12 mm SUS420J2 stainless steel rod with an M10x1.25 thread. The barrel is extruded aluminum with sensor grooves on both sides, and the PT tapered port threads are G1/8.
Because the adjuster acts as a retract-end stop rather than a locking brake, it cannot hold loads without live air pressure. The integrated variable air cushions at both ends are 27 mm long, and the -S magnet enables position sensing with CMSE reed or DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-40S Is Used
Machine Changeover
Dial in the 760-800 mm travel window during product size changes to set new end stops without physically replacing the cylinder.
Material Transfer
Fine-tune the retract position on a long-stroke conveyor diverter to accommodate varying package dimensions on the fly.
End-Position Tuning
Trim the stroke by up to 40 mm at commissioning to perfect the tooling alignment without machining external stopper blocks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-40S the Right Cylinder?
Choose this 32 mm bore if your application requires up to 724 N of push force at 0.9 MPa, or step up to the 40 mm bore for 879 N at 0.5 MPa if your load demands more thrust. The 40 mm adjustment range is ideal for fine-tuning the end position during machine setup or product changeover without swapping cylinders or adding external stops. For load-holding without live air pressure, consider the SAIL or BSAI series instead.
With an 800 mm stroke, the 12 mm rod is susceptible to side loading; always use an external guide to prevent rod bending. This SAIJ model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552.
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 SAIJ32AX800-40S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 40 mm, providing a 760-800 mm travel window. It only sets the end position; it does not lock or hold the load without live air pressure.
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf of push force.
