About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-30
The AirTAC SAIJ100X260-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 260 mm stroke that can be fine-tuned backward by up to 30 mm, creating a precise 230-260 mm usable travel window for commissioning flexibility.
Delivering 7068 N of push force at 0.9 MPa, this 100 mm bore actuator handles heavy loads. It features a SUS304 stainless steel rod for corrosion resistance, dual-sided sensor grooves, and variable air cushions at both ends to decelerate moving masses smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-30 Is Used
Product Changeover
Dial in the 230-260 mm travel window during format changes on packaging lines without adding external mechanical stops.
End-Position Tuning
Fine-tune the retract stroke at machine commissioning to perfectly time the 7068 N push force against mechanical stops.
Heavy Assembly Press
Leverage the 100 mm bore thrust and SUS304 rod for robust pressing operations requiring washdown corrosion resistance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-30 the Right Cylinder?
Select this 100 mm bore actuator when an application requires substantial thrust—stepping down to an 80 mm bore yields 4523 N at 0.5 MPa, while this model provides 3927 N at the same pressure. The adjustable stroke is chosen over a fixed SAI cylinder when machinery requires variable end-stops or product changeover without physically swapping the actuator. Mounting utilizes a reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Threaded ports are PT type.
Because the stroke is 260 mm, an external guide is recommended to prevent excessive side-loading on the rod. Note that the rear adjuster acts solely as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock or AirTAC SAIL or BSAI cylinders.
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 SAIJ100 Adjustable Cylinder SAIJ100BX260-30 FAQ
At 0.9 MPa, this 100 mm bore cylinder generates 7068 N of push force and 3681 N of pull force. It can deliver a maximum of 801 kgf at 1.0 MPa.
A rear screw stopper trims the effective retract travel back by up to 30 mm from the 260 mm nominal stroke, providing a 230-260 mm adjustable window. It functions as a stop, not a lock, and requires live air to maintain position.
