About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-40S
The AirTAC SAIJ32X115-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 115 mm stroke that can be dialed back by up to 40 mm, yielding a usable travel window of 75 to 115 mm for precise end-position tuning during commissioning.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the PT tapered porting ensures a tight, reliable pneumatic connection.

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 SAIJ32AX115-40S Is Used
Machine Changeover
Dial in the exact retract end-stop from 75 to 115 mm during product size transitions without disassembling the actuator assembly.
End-Position Tuning
Fine-tune the final retract position during machine commissioning to compensate for mechanical wear or sensor placement.
Light-Duty Testing
Vary the stroke distance for low-force (402 N at 0.5 MPa) testing rigs where the exact contact point must be adjusted on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-40S the Right Cylinder?
Stepping up to a 40 mm bore raises the 0.5 MPa push force to 628 N for heavier payloads, while dropping to a smaller bore would reduce the force below this threshold. The 40 mm adjustment range is ideal for product-size changeovers, allowing you to fine-tune the retract position without swapping the cylinder or adding external stops.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 115 mm nominal stroke, PT port threads, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For true load-holding, consider an AirTAC SAIL or BSAI series cylinder.
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 SAIJ32AX115-40S FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 115 mm down to as little as 75 mm. This creates a 75-115 mm adjustable window, but it does not lock the load without continuous air pressure.
