About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX275-100
The AirTAC SAIJ80X275-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 175-275mm usable travel window from its 275mm nominal stroke. This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
The external rear stopper allows precise end-position tuning during commissioning without adding external stops. It utilizes a reduced mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. The adjuster acts strictly as a travel stop for deceleration, not a lock, so it cannot hold loads 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 SAIJ80BX275-100 Is Used
Product Changeovers
Dial back the stroke by up to 100mm to accommodate different product lengths on the same line without physically replacing the actuator.
End-Position Tuning
Fine-tune the retract end-stop during machine commissioning to perfect timing and avoid adding bulky external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX275-100 the Right Cylinder?
The 100mm adjustment range is ideal for machines processing multiple product sizes, allowing you to dial back the stroke by up to 100mm during changeovers rather than swapping cylinders. For fixed travel without a stopper, the standard SAI cylinder is preferred.
Because the 275mm stroke exceeds 300mm guidelines for unsupported travel, guide external loads carefully to prevent rod side-loading. If the application requires true load holding without continuous air pressure, use a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the rear stopper.
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 SAIJ80BX275-100 FAQ
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this SAIJ80X275-100 model, you can trim the 275mm nominal stroke back by up to 100mm, creating a usable travel window of 175-275mm.
The operational speed ranges from 30-800mm/s, and it features a G3/8 port.
