About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-75
The AirTAC SAIJ80X175-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows you to fine-tune the retract end position at commissioning without swapping out the barrel or adding external stops.
Featuring a SUS304 stainless steel rod for corrosion resistance, this model uses PT tapered ports and operates at speeds of 30-800mm/s. The rear adjuster acts purely as a mechanical stop and works alongside the variable air cushions at both ends to decelerate the load. It does not hold the load without live air; for pilot-operated locking, consider the SAIL or BSAI series.

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 SAIJ80BX175-75 Is Used
Product Changeover
Dial the stroke back by up to 75mm during production line changeovers to accommodate different package lengths instantly.
End-Stop Tuning
Fine-tune the retract position during commissioning to achieve exact positioning without fabricating external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-75 the Right Cylinder?
The 75mm adjustment range is ideal for machines processing varying product sizes, letting you dial in the exact end-stop on the fly. Because it shares standard ISO 15552 mounting dimensions, it drops directly into existing footprints using the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting styles. To track position, you would need a magnet (-S) variant to use AirTAC CMSE reed or DMSE electronic sensors.
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 SAIJ80BX175-75 FAQ
The nominal stroke is 175mm, but the rear adjuster allows you to shorten the effective travel by up to 75mm, creating a usable window of 100-175mm depending on your setup.
No, the rear adjuster is a travel stop, not a lock. The cylinder requires live air to maintain position. For load-holding without pressure, use the SAIL or BSAI series.
