About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-40
The AirTAC SAIJ80X175-40 is a double-acting, double-rod profile cylinder dimensionally interchangeable per ISO 15552. It features a rear stroke adjuster that allows you to fine-tune the effective travel window down to 135 mm from the 175 mm nominal stroke without adding external stops.
This variant uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It carries PT (tapered) G3/8 ports and provides variable air cushioning at both ends to manage deceleration across its 30-800 mm/s speed range.

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 SAIJ80AX175-40 Is Used
Machine Changeover
Dial in the 135-175 mm travel window during product size transitions to set new end stops without physically swapping the cylinder.
Assembly Positioning
Fine-tune the retract end-position during commissioning to align heavy 2513 N press fits accurately.
Conveyor Diverter
Adjust the stroke length on-site to alter the diverting distance of heavy pallets without re-engineering the pneumatic layout.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-40 the Right Cylinder?
The 40 mm adjustment range is ideal for machine setups requiring precise end-position tuning during commissioning or product changeovers. Because the rear adjuster acts only as a travel stop and the cushions manage deceleration, this cylinder cannot hold a load without live air; for true fail-safe load holding, select an AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder. To match this ISO 15552 replacement exactly, verify the 175 mm stroke, 40 mm adjuster, PT G3/8 port, and your preferred mounting bracket from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ80AX175-40 FAQ
The rear adjuster allows you to shorten the effective stroke by up to 40 mm. This creates a usable travel window of 135 to 175 mm, letting you fine-tune the end position at commissioning without external stops.
At 0.9 MPa, the push force increases to 4523 N.
