About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-20
The AirTAC SAIJ80X120-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 100 to 120 mm, allowing you to dial back the nominal 120 mm stroke by up to 20 mm during commissioning.
This model uses a SUS304 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting, while the rear adjuster acts purely as a travel stop to set end positions without holding the load.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX120-20 Is Used
Machine Setup Tuning
Fine-tune the exact end-of-stroke position during initial machine commissioning to perfect a pressing or forming operation.
Product Changeover
Quickly adjust the travel stop from 100 to 120 mm to handle varying package sizes or product lengths on a single line.
Variable End Stops
Use the rear screw to set precise retract positions for different tooling fixtures without installing external physical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-20 the Right Cylinder?
Since the stroke is 120 mm, side-loading is minimal, but always ensure the rod thread (M20x1.5) is properly aligned. To replace an ISO 15552 cylinder, match the 80 mm bore, 120 mm stroke, 20 mm adjustment, PT G3/8 port, and standard mounting options (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 SAIJ80BX120-20 FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 120 mm down to 100 mm, giving a 100-120 mm usable window. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
