About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-100S
The AirTAC SAIJ80X900-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 900 mm nominal stroke by up to 100 mm. This yields a usable travel window of 800-900 mm, providing fine end-position tuning at commissioning without the need to swap the cylinder or bolt on external stops. Built with an SUS420J2 stainless steel rod (option A), it handles heavy loads with a push force of 2513 N and a pull force of 2268 N at 0.5 MPa.
This unit includes a magnet for position detection and is compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. It uses a PT tapered G3/8 port and operates at speeds between 30 and 800 mm/s. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-100S Is Used
Variable End-Stop Machining
Dial in the exact 800-900 mm travel window during machine setup to accommodate varying part lengths without replacing the entire actuator.
Product Changeover Systems
Quickly retune the retract end-position on packaging lines when switching between different box sizes or product profiles.
Long-Stroke Material Handling
Utilize the 2513 N push force to move heavy pallets or workpieces, adjusting the stopper to fine-tune the final resting position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-100S the Right Cylinder?
Choose this adjustable-stroke model when an application requires variable end-stops or frequent product-size changeovers, rather than a fixed-stroke SAI cylinder. If you need less force, stepping down to a 63 mm bore provides 1402 N of pull at 0.5 MPa; if your application demands more holding power, a 100 mm bore offers 3681 N of pull. Because the 900 mm stroke is long, the 25 mm rod diameter and M20x1.5 thread carry substantial side loads, but an external guide is still recommended to prevent rod binding.
This cylinder is dimensionally interchangeable per ISO 15552 mounting interfaces. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For applications requiring the load to be held without continuous live air, note that this cylinder's adjuster is only a stop; consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI series cylinders instead.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80AX900-100S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. At its maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window of 800 to 900 mm from the 900 mm nominal stroke, allowing precise end-position tuning without changing the cylinder.
