About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-50
The AirTAC SAIJ125X95-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 45-95 mm from its 95 mm nominal stroke. The extruded aluminum barrel features sensor grooves on both sides for straightforward position monitoring.
This model features a 32 mm carbon steel rod and a PT G1/2 port. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ125X95-50 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 45-95 mm window during machine setup, allowing operators to fine-tune end positions without swapping cylinders.
Product Size Changeover
Quickly adapt heavy-duty production lines to varying product dimensions by adjusting the 50 mm travel range at the rear stopper, minimizing downtime.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-50 the Right Cylinder?
Choose this 125 mm bore cylinder when an application requires substantial thrust—such as 6136 N at 0.5 MPa—but also demands variable end-stops for product changeovers. The adjustable stroke prevents the need to swap cylinders or bolt on external stops when dialing in final positions.
For ISO 15552 replacement matching, ensure the 95 mm stroke, 50 mm adjustment range, PT G1/2 port, and standard carbon steel rod align with your mounting requirements. Because the nominal stroke is under 300 mm, side-load concerns are reduced, though an external guide is still recommended for heavy lateral loads. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, select an AirTAC SAIL or BSAI 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 SAIJ125 Adjustable Cylinder SAIJ125X95-50 FAQ
At 0.9 MPa, the push force increases to 11045 N.
The rear mechanical stopper allows you to trim the effective travel back by up to 50 mm from the 95 mm nominal stroke, creating a usable 45-95 mm positioning window. This adjuster functions as a travel stop and does not hold the load without live air pressure.
