About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X10-10S
The AirTAC SAIJ125X10-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a carbon steel piston rod and a PT tapered port. Because the nominal stroke is only 10 mm and the adjustment range is also 10 mm, this specific SKU provides a highly specialized 0-10 mm usable travel window, allowing the effective retraction end-position to be dialed back completely to a zero-stroke mechanical stop.
The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.

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 (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 SAIJ125X10-10S Is Used
End-Stop Calibration
The 0-10 mm usable travel window lets technicians fine-tune the retraction end-position during machine commissioning without adding external mechanical stops.
Product Changeover
Ideal for lines running variable product sizes, where the rear screw quickly modifies the effective clamping stroke on the fly without swapping the cylinder.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X10-10S the Right Cylinder?
The rear adjustment screw acts purely as a mechanical travel stop for commissioning end-position tuning; it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, consider an SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints. The correct mounting accessory set for this SAIJ series includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, deliberately omitting FB, CA, CB, and CR options. To replicate this exact configuration, specify a 125 mm bore, 10 mm stroke, 10 mm adjustment, PT port thread, carbon steel rod, and the -S magnet option.
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 SAIJ125X10-10S FAQ
With a 10 mm nominal stroke and a 10 mm adjustment code, the usable travel window is 0-10 mm, allowing the stroke to be trimmed back completely.
No, the rear adjuster functions only as a travel stop to set the end position and does not hold the load without live air. For load-holding, use an SAIL or BSAI cylinder. This -S model includes a magnet for position sensing with AirTAC CMSE reed switches and DMSE electronic sensors.
