About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX30-30
The AirTAC SAIJ80X30-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a 30 mm nominal stroke and a 30 mm adjustment code, the effective travel window can be fine-tuned anywhere from 0 to 30 mm. This allows operators to dial in the exact retract end-position during commissioning without adding external stops.
This model uses a SUS304 stainless steel rod for superior corrosion resistance and is fitted with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

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 SAIJ80BX30-30 Is Used
End-Position Tuning
Dial in the exact retract distance from 0 to 30 mm during machine commissioning to perfect gripping or clamping depth without swapping hardware.
Product Changeover
Quickly adjust the stroke stop on the production line when handling slightly different product sizes, utilizing the full 30 mm trim range.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX30-30 the Right Cylinder?
The SAIJ80X30-30 is ideal for machine setups requiring frequent product changeovers. Because the stroke is 30 mm, external side-load guides are less critical than on longer strokes, but the 25 mm rod diameter handles standard loads well.
For a direct ISO 15552 replacement, match the 80 mm bore, 30 mm stroke, 30 mm adjustment, PT G3/8 port, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember that the rear adjuster only sets the travel end; for load-holding without live air, use an external rod lock or pilot-operated check valve.
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 SAIJ80BX30-30 FAQ
At the maximum rated pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 30 mm from the nominal 30 mm stroke, creating a 0-30 mm usable travel window. It only sets the travel end and does not lock or hold the load without live air pressure.
