About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX260-10S
The AirTAC SAIJ125X260-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 250-260 mm, allowing you to dial back the nominal 260 mm stroke by up to 10 mm during commissioning. Delivering 6136 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for position sensing.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops when fine-tuning end positions. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic sensors. It operates at speeds of 30-500 mm/s and uses a PT tapered G1/2 port.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX260-10S Is Used
Machine Changeover
Quickly fine-tune the 250-260 mm travel end-stop when switching between product sizes on a packaging line without changing the cylinder.
End-Position Calibration
Dial in the exact retracted position during initial commissioning to perfect tooling alignment without adding external mechanical stops.
Heavy-Duty Forming
Leverage the 6136 N push force at 0.5 MPa for pressing operations while relying on the SUS420J2 rod to withstand harsh environments.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX260-10S the Right Cylinder?
Choose this SAIJ125X260-10-S model when your application requires precise end-position tuning at commissioning or during product changeover. If your force requirements are lower, stepping down to a 100 mm bore yields 3927 N at 0.5 MPa, while moving up to a 160 mm bore provides 10053 N. Since the 260 mm stroke exceeds 300 mm? No, but for any stroke over 300 mm, an external guide is recommended to manage side loads.
The rear adjuster acts strictly as a travel stop to set deceleration, not a lock; it will not hold a load without live air pressure. For true load-holding without continuous air, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. To match this ISO 15552 interchangeable cylinder, specify the 125 mm bore, 260 mm stroke, 10 mm adjustment, PT G1/2 port, 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 SAIJ125AX260-10S FAQ
At a 0.5 MPa operating pressure, this 125 mm bore cylinder generates 6136 N of push force and 5734 N of pull force. It can reach up to 1251 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, providing a usable travel window of 250 to 260 mm. This stopper sets the travel end and deceleration point, but it does not lock or hold the load without continuous air pressure.
