About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-100
It features a SUS304 stainless steel rod and PT tapered ports. By incorporating a 100mm adjustment range on a 120mm nominal stroke, this model provides an exceptionally wide usable travel window from 20 to 120mm, allowing precise end-position tuning without swapping hardware.
The rear adjuster acts purely as a mechanical stop to set the retract position and relies on the integrated air cushion for end-of-stroke deceleration. It is not a locking mechanism and will not hold a load without live air pressure. For position holding without continuous air, an external pilot-operated check valve or a related AirTAC locking cylinder like the SAIL or BSAI is required.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-100 Is Used
Variable Product Changeover
Dial in the exact end-stop for different package lengths on a packaging line, utilizing the full 20-120mm travel window to switch formats rapidly without mechanical rebuilds.
Machine Setup Calibration
Fine-tune the retract position during commissioning to perfectly align a 2513N clamping force against varying workpiece tolerances.
Adjustable Ejector Stroke
Control the ejection distance of parts from a machine bed, safely trimming the stroke back from 120mm to prevent ejecting components into downstream equipment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-100 the Right Cylinder?
Choose this 80mm bore when an application demands high thrust but highly variable end-stops, such as accommodating multiple product sizes on a single line. This SKU omits the magnet, so it cannot host CMSE reed or DMSE electronic sensors without modification. To match this cylinder exactly for an ISO 15552 replacement, specify the 80mm bore, 120mm stroke, 100mm adjust, PT ports, SUS304 (B) rod, and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ80BX120-100 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window from 20mm to 120mm, enabling precise end-position tuning at commissioning without adding external stops.
