About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-75
The AirTAC SAIJ80X75-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 0 up to 75 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific SKU utilizes a SUS420J2 stainless steel rod for enhanced corrosion resistance and is fitted with PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to set the retract end-position during commissioning; it does not lock or hold the load without live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80AX75-75 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 0 to 75 mm on the fly for multi-format packaging lines without installing external physical stops.
Machine Setup & Commissioning
Fine-tune the end-of-stroke position during initial machine build to perfect timing sequences, avoiding the need to machine custom spacer blocks.
Product-Size Changeover
Rapidly adapt the cylinder's effective travel window to accommodate new product dimensions on automated conveyors during production shifts.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-75 the Right Cylinder?
The 75 mm adjustment range is exceptionally large, effectively allowing you to dial the stroke down to zero, making it ideal for highly variable product changeovers without swapping hardware. For load-holding without continuous air, explore the SAIL or BSAI series instead. When replacing an ISO 15552 cylinder, match the 80 mm bore, 75 mm stroke, PT port threads, 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 SAIJ80AX75-75 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear mechanical screw acts as a travel stop, allowing you to reduce the effective stroke from its 75 mm nominal length down to 0 mm. It only sets the end position; it does not function as a brake or lock.
