About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X10-10
The AirTAC SAIJ125X10-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 10 mm nominal stroke that can be dialed back by up to 10 mm, yielding a highly precise 0-10 mm usable travel window for exact end-position tuning.
This model features a carbon steel rod and PT tapered port threads. It utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later.

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 SAIJ125X10-10 Is Used
Short-Stroke Clamping
Provides exact 0-10 mm clamping travel for heavy parts, allowing operators to dial in the perfect grip depth during machine setup.
End-Position Tuning
Ideal for applications where the final retract position must be micro-adjusted on the fly to accommodate slight variations in product thickness.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X10-10 the Right Cylinder?
Choose this adjustable cylinder when you need to fine-tune the retract end-stop during commissioning without adding external physical stops. If your application requires less force, stepping down to a 100 mm bore yields 3927 N at 0.5 MPa, whereas a 160 mm bore provides 10053 N for heavier loads. Because the stroke is under 300 mm, side-load stress is minimal, but an external guide is still recommended for optimal rod bearing life.
For direct replacements, match the 125 mm bore, 10 mm stroke, 10 mm adjustment range, PT port thread, and the specific mounting accessory. Keep in mind the rear adjuster acts only as a travel stop; it cannot hold a load without live air pressure. For true load-holding, consider the SAIL or BSAI cylinder series.
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 SAIJ125X10-10 FAQ
The maximum thrust is 1251 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel by up to 10 mm. Since the nominal stroke is 10 mm, you can set the usable travel anywhere within a 0-10 mm window to perfectly tune the end position without swapping the cylinder.
