Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-10
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 900mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-10
The AirTAC SAIJ80X900-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 25 mm rod and a usable travel window of 890-900 mm, allowing you to dial back the stroke by up to 10 mm during commissioning. This bore size delivers 2513 N of push force at 0.5 MPa and incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the 900 mm stroke is long, the 25 mm rod thread and diameter carry substantial side-load capacity, though an external guide is still recommended for unsupported lengths. The rear adjuster acts purely as a travel stop to fine-tune the end position without swapping cylinders.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-10 Is Used
Machine Setup Tuning
Dial in the exact 890-900 mm end-stop during commissioning without adding external physical stops to the machine frame.
Product Changeover
Quickly accommodate minor variations in part dimensions on a production line by adjusting the rear screw up to 10 mm.
Long-Stroke Assembly
Execute 900 mm travel assembly or press operations where a 2513 N thrust class and fine end-position trimming are required.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-10 the Right Cylinder?
Choose this 80 mm bore when 50 mm is insufficient (982 N at 0.5 MPa) and 100 mm (3927 N at 0.5 MPa) is oversized. The 10 mm adjustable range is selected when you need minor end-position tuning for machine setup or product changeover rather than a fully variable stroke. The rear screw sets the travel end but does not lock the load; for true position holding without live air, use an AirTAC SAIL or BSAI cylinder.
To replace an ISO 15552 cylinder, match the 80 mm bore, 900 mm stroke, 10 mm adjustment, PT G3/8 port, and the required mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted. As an 80 mm bore, it operates at 30-800 mm/s and uses variable air cushions at both ends.
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 SAIJ80 Adjustable Cylinder SAIJ80AX900-10 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 900 mm down to 890 mm. It acts as a mechanical stop to fine-tune the end position, but it does not lock or hold the load without live air pressure.
