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. 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.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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?
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 the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf of push force.
