About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-30
The AirTAC SAIJ80X145-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 2513N pull force at 0.5 MPa and provides a usable travel window of 115-145 mm, allowing you to dial in the exact retract position without external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with a SUS304 stainless steel rod, this variant is well-suited for environments where corrosion resistance is a priority. It features PT tapered port threading (G3/8) and a 25mm rod diameter that handles demanding loads. The rear adjuster functions strictly as a travel stop for end-position tuning, not a lock, meaning live air pressure is required to hold the 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 SAIJ80BX145-30 Is Used
Machine Changeover
Quickly fine-tune the retract distance during product size transitions on a packaging line without replacing the cylinder.
End-Position Tuning
Dial in the exact 115-145mm travel window during commissioning to align tooling precisely, eliminating mechanical shimming.
Variable End Stops
Set custom stroke endpoints for automated assembly equipment that processes multiple part lengths on the same fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-30 the Right Cylinder?
The adjustable stroke is ideal for machine setup and product changeovers, letting you fine-tune the 145mm travel down to 115mm on the fly instead of swapping to a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI cylinder. As a dimensionally interchangeable ISO 15552 unit, it matches replacements by bore, stroke, 30mm adjustment, PT port, and mounting set (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 SAIJ80BX145-30 FAQ
The rear adjuster allows you to shorten the effective stroke by up to 30mm, creating a 115-145mm usable travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
At 0.7 MPa, the push force increases to 3518N.
