About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-40S
The AirTAC SAIJ125X95-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This model carries a 95mm nominal stroke that can be dialed back by up to 40mm, creating a precise 55-95mm usable travel window for product changeovers. It uses a PT tapered port thread and a robust 32mm carbon steel rod with an M27x2 thread, providing high side-load resistance without needing tie-rod construction.

Theoretical Output Force (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |
| 0.7 MPa | 8027 N | — |
| Max (@1.0 MPa) | 1169 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 SAIJ125 Adjustable Cylinder SAIJ125X95-40S Is Used
Product Size Changeovers
Dial in the 55-95mm travel window during line changeovers to accommodate different package lengths without replacing the actuator.
Adjustable Ejection
Vary the ejection stroke distance on heavy assemblies by adjusting the rear stopper, ensuring parts clear the machine safely.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-40S the Right Cylinder?
The 40mm adjustment range is ideal for adapting to varying product sizes without swapping the cylinder or bolting on external stops.
The rear adjuster acts purely as a travel stop and works with the air cushions to decelerate the load, but it does not hold the load without live air pressure. For dead-end holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ125 Adjustable Cylinder SAIJ125X95-40S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 1251 kgf.
The rear adjuster screw allows you to shorten the 95mm nominal stroke by up to 40mm, creating a usable travel window of 55-95mm. The adjuster acts as a mechanical stop to set the end position and must not be relied upon as a load-holding lock.
