About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX30-10
It features a SUS304 stainless steel rod and PT tapered port threads. By turning the rear screw, you achieve a usable travel window of 20-30mm, allowing precise end-position calibration without external stops.
This adjustable-stroke design is ideal for short-stroke setups requiring exact positioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. While the rear stopper sets the travel limit, remember it is not a locking device; the cylinder relies on live air to maintain position under load.

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 SAIJ80BX30-10 Is Used
Short-Stroke Clamping
Ideal for clamping parts where the exact 20-30mm travel window allows micro-adjustments to accommodate varying material thicknesses without repositioning the fixture.
Machine Commissioning
Enables technicians to fine-tune the retract end-position during initial setup, ensuring precise alignment without swapping out the entire cylinder.
Product Diversion
Useful on conveyor lines where a short, adjustable stroke is needed to deflect items of slightly different sizes accurately.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX30-10 the Right Cylinder?
Select this 80mm bore cylinder when an application demands high force in a compact space but requires micro-adjustments to the end-stop. Choose the SAIJ adjustable version over a fixed SAI cylinder when you anticipate needing commissioning tweaks or product changeovers.
For an exact ISO 15552 replacement, match the 80mm bore, 30mm nominal stroke, 10mm adjustment range, PT port thread, and SUS304 rod material. Note that this cylinder does not include a magnet (-S), so position sensing via CMSE or DMSE switches is not supported without modification. Since the nominal stroke is only 30mm, external side-load guides are less critical than on longer strokes, but proper alignment remains essential.
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 SAIJ80BX30-10 FAQ
At the maximum pressure of 1.0 MPa, the push force reaches 513 kgf.
The rear adjuster screw allows you to trim the effective stroke within a 20-30mm window. This means you can dial back the nominal 30mm stroke by up to 10mm to achieve the exact end-position required, without using external stoppers.
