About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX550-10
The AirTAC SAIJ80X550-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear mechanical adjuster that creates a 540 to 550 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it handles substantial pneumatic workloads. The extruded aluminum barrel includes dual sensor grooves, allowing straightforward integration of CMSE or DMSE switches if position feedback is added later.
This variant utilizes an SUS420J2 stainless steel rod (material code A) for enhanced resistance to corrosion and surface wear. It connects via PT tapered G3/8 ports and relies on standard adjustable air cushions at both ends to decelerate the 25 mm rod smoothly. The rear stopper acts purely as a travel limit and does not lock the load without continuous air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX550-10 Is Used
Changeover Calibration
Dial in the 540-550 mm retract position precisely during product size changeovers without adding external physical stops to the machine frame.
Material Diversion
Provides robust 2513 N push force at 0.5 MPa for actuating heavy diverter gates on high-throughput packaging conveyors.
Press Positioning
Sets accurate end-stops for light pressing or seating tasks, relying on the SUS420J2 stainless rod to withstand minor abrasive contact.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX550-10 the Right Cylinder?
Select this 80 mm bore when an application requires more thrust than a 63 mm cylinder provides (1559 N at 0.5 MPa) but does not need the bulk of a 100 mm unit (3927 N). The 10 mm adjustment range is ideal for fine-tuning the retract end position during machine commissioning or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. Because the nominal stroke is 550 mm, an external guide rail is strongly recommended to prevent excessive side-loading on the extended rod.
For a direct ISO 15552 replacement match, verify the 80 mm bore, 550 mm stroke, PT G3/8 port thread, and the required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. If the machine requires true load-holding without live air pressure, a standard SAIJ is insufficient; consider an AirTAC SAIL or BSAI locking 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 SAIJ80 Adjustable Cylinder SAIJ80AX550-10 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 540 to 550 mm travel window. It functions as a mechanical stop to fine-tune the end position and does not hold the load without continuous air pressure.
