Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10
The AirTAC Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø125mm bore and 95mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10
The AirTAC SAIJ125X95-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 6136N of push force at 0.5 MPa. Its 95mm nominal stroke can be dialed back by up to 10mm, creating an 85-95mm usable travel window for precise end-position tuning during machine commissioning. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This model uses a 32mm carbon steel rod with an M27x2 thread and PT tapered ports. It supports a reduced set of ISO 15552 mountings—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting FB, CA, CB, and CR options. The rear adjuster acts purely as a travel stop to set the retraction end, meaning it cannot hold a load without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10 Is Used
Precision End-Position Tuning
Dial in the exact 85-95mm retraction point during machine setup to achieve precise material positioning without mechanical shims.
Product Line Changeover
Quickly adjust the stroke by up to 10mm to accommodate slight variations in product dimensions on a shared manufacturing line.
Heavy-Duty Forming
Leverage the 6136N push force at 0.5 MPa for pressing or forming tasks that require both high power and adjustable travel limits.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10 the Right Cylinder?
Select this 125mm bore cylinder when an application requires heavy thrust—such as 6136N push at 0.5 MPa—combined with a variable end-stop. If you need less force, stepping down to an 80mm bore yields 2513N push at 0.5 MPa. The adjustable-stroke design is ideal for product-size changeovers on a line, allowing you to fine-tune the 85-95mm travel window without swapping the cylinder or adding external stops. For load-holding without live air, consider an AirTAC SAIL or BSAI cylinder, or use an external rod lock.
When replacing an ISO 15552 cylinder, match the 125mm bore, 95mm stroke, 10mm adjustment range, PT port threads, and the specific mounting subset. Because the stroke is under 300mm, side-load stress is minimized, but the heavy 32mm rod still requires proper alignment to prevent premature seal wear.
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 SAIJ125X95-10 FAQ
At 0.5 MPa operating pressure, this 125mm bore cylinder provides 6136N of push force and 5734N of pull force. At 0.7 MPa, the push force increases to 8590N.
The rear adjuster acts as a mechanical stop that shortens the 95mm nominal stroke by up to 10mm, providing an 85-95mm usable travel window. It sets the end position but does not lock the load without continuous air pressure.
