About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-20S
The AirTAC SAIJ80X130-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to dial back the nominal 130 mm stroke by up to 20 mm. This yields a precise 110-130 mm usable travel window, ideal for fine-tuning end positions during machine commissioning without swapping out hardware. It features a SUS304 stainless steel rod for superior corrosion resistance and includes a standard magnet for position sensing.
The extruded aluminum barrel integrates sensor grooves on both sides to accept CMSE reed and DMSE electronic switches. The rear stopper solely dictates the travel end point and deceleration; it does not function as a lock, meaning live air pressure is required to hold the load in place.

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 SAIJ80BX130-20S Is Used
Machine Changeover
Dial in the 110-130 mm travel window during product size changeovers to set exact end positions without machining new stopper blocks.
Press Fit Tuning
Fine-tune the pressing depth of bearings or pins at commissioning by adjusting the rear screw, preventing over-travel damage.
Variable End Stops
Adapt diverter or pusher mechanisms on a packaging line to handle slightly different carton lengths using the 20 mm adjustment range.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-20S the Right Cylinder?
Choose this 80 mm bore when your application requires substantial thrust, pushing 3518 N at 0.7 MPa. If your force requirements are lower, stepping down to a 63 mm bore yields 2182 N at 0.5 MPa, reducing air consumption. The integrated -20 mm adjustment mechanism is selected over a fixed-stroke SAI when a process requires variable end-stops to accommodate slight product size changes on the fly.
To match this cylinder for an ISO 15552 replacement, verify the 130 mm stroke, 20 mm adjustment range, PT G3/8 port thread, and the -S magnet option. The standard SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the 25 mm rod and M20x1.5 thread handle high loads, they manage side loads well, though any stroke over 300 mm would require an external guide.
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 SAIJ80BX130-20S FAQ
The rear adjuster screw acts as an external stopper that shortens the effective stroke. For this model, you can trim the 130 mm nominal stroke back by up to 20 mm, giving an adjustable travel window of 110 to 130 mm. Note that this adjuster is a travel stop and does not lock or hold the load without continuous air pressure.
If you increase the pressure to 0.9 MPa, the push force reaches 4523 N.
