About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-10
The AirTAC SAIJ125X160-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 6136N of push force at 0.5 MPa. By turning the external stopper screw, you can fine-tune the effective travel within a 150-160mm window, providing exact end-position calibration without swapping out the entire unit.
This bore features a 32mm piston rod with an M27x2 thread to manage high side loads, and the standard extruded aluminum barrel includes sensor grooves on both sides. It omits the FB, CA, CB, and CR mountings, utilizing a reduced set of ISO 15552 interfaces including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-10 Is Used
Heavy Fixture Clamping
Dial in the exact 150-160mm clamping reach during machine commissioning to accommodate varying workpiece tolerances without external shims.
Product Size Changeover
Quickly adjust the end-of-stroke position on a packaging line when switching to a different product size, minimizing downtime.
End-Stop Calibration
Fine-tune the retraction point during assembly station setup to prevent tooling crashes and ensure precise mechanical alignment.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-10 the Right Cylinder?
Choose this 125mm bore when an 80mm cylinder (providing 2513N push at 0.5 MPa) lacks the thrust for your tooling, but a 160mm bore is oversized. The 10mm rear adjuster is ideal for final machine setup or product changeover, allowing you to dial in the 160mm stroke precisely without adding external stops. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding requirements without continuous pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. This configuration includes a SUS420J2 stainless steel rod and PT tapered ports.
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 SAIJ125AX160-10 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 screw acts as a mechanical stop, allowing you to shorten the nominal 160mm stroke by up to 10mm, creating a 150-160mm usable travel window. It only sets the travel end and does not lock the load without live air pressure.
