About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX180-10S
The AirTAC SAIJ125X180-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 6136N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod. The built-in magnet supports position sensing. By turning the rear stopper screw, you can trim the effective travel, providing a usable 170-180mm adjustment window from the 180mm nominal stroke.
This adjustable design allows precise end-position tuning during commissioning without adding external stops or swapping cylinders. It includes variable air cushions at both ends and dual-side sensor grooves for CMSE reed or DMSE solid-state switches. The adjuster acts purely as a travel stop to set deceleration limits, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX180-10S Is Used
Machine Changeover
Fine-tune the 170-180mm end-stop during product size transitions without physically swapping cylinders.
End-Position Calibration
Dial in the exact retract position during machine commissioning to ensure precise alignment.
Assembly Pressing
Leverage 6136N of thrust for pressing components while retaining a 10mm setup buffer.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX180-10S the Right Cylinder?
Select this 125mm bore model when a 100mm bore (offering 3927N push at 0.5 MPa) lacks sufficient thrust, but you want to avoid stepping up to a 160mm bore that delivers 10053N. The 10mm adjustment range is ideal for applications requiring exact end-position calibration during product changeovers. For fixed travel without fine-tuning, a standard SAI cylinder is sufficient.
To replace an ISO 15552 cylinder, match the 125mm bore, 180mm stroke, PT tapered port threads, and -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 180mm stroke is under 300mm, side-load concerns are minimal, but always guide heavy loads externally. If true load-holding without air pressure is required, use an SAIL or BSAI cylinder instead.
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 SAIJ125AX180-10S FAQ
At 0.5 MPa operating pressure, this 125mm bore cylinder provides 6136N of push force and 5734N of pull force. It can reach up to 11045N push force at 0.9 MPa.
A rear stopper screw lets you shorten the 180mm nominal stroke by up to 10mm, creating a 170-180mm usable travel window. The adjuster acts as a mechanical stop for end-position tuning and does not lock the load without air pressure.
