About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-20
The AirTAC SAIJ80X220-20 is a double-acting ISO 15552 profile cylinder with a rear-mounted stroke adjuster. It provides a 200-220 mm usable travel window, letting you dial in the exact retract position during commissioning. The 80 mm bore generates 2513 N of pull force at 0.5 MPa, making it suitable for heavier actuation tasks.
This model features a 25 mm carbon steel piston rod and an M20x1.5 rod thread, which together handle higher side loads than smaller bores. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set omits FB, CA, CB, and CR brackets, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-20 Is Used
Machine Changeover
Quickly adjust the 200-220 mm retract stop to accommodate new product lengths on a packaging line without swapping out the entire cylinder.
End-Position Tuning
Fine-tune the final resting position of a heavy press fixture during commissioning, absorbing mechanical tolerances directly at the rear stopper.
Variable End Stops
Dial in the exact clamping depth on an assembly station, using the 20 mm adjustment window to adapt to material thickness variations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-20 the Right Cylinder?
Choose this 80 mm bore when an application requires substantial force, such as the 2513 N pull at 0.5 MPa, but the exact end-of-stroke needs on-the-fly tuning within a 200-220 mm window. If your process demands less force, stepping down to a 63 mm bore provides 1402 N of pull, whereas stepping up to a 100 mm bore yields 3681 N. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 220 mm nominal stroke, 20 mm adjustment range, PT tapered port thread, and the specific mounting bracket. Because this unit lacks a magnet, it cannot host CMSE or DMSE sensors without specifying the -S option. The 220 mm stroke is under the 300 mm threshold, but you should still ensure external guidance for heavy lateral loads.
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 SAIJ80X220-20 FAQ
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this model, the 220 mm nominal stroke can be dialed back by up to 20 mm, providing a usable travel window of 200 to 220 mm. It only sets the travel end and does not hold the load without live air.
At 0.5 MPa, the SAIJ80X220-20 generates 2513 N of pull force and 2268 N of push force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
