About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-75S
The AirTAC SAIJ80X200-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 125-200 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for position detection.
Equipped with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, it handles speeds of 30-800 mm/s. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without adding external stops. It is not a lock, so the cylinder 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 SAIJ80AX200-75S Is Used
Product Changeover Dials
Quickly adjust the end-stop from 200 mm down to 125 mm to accommodate different product lengths on the same line without changing cylinders.
Commissioning End-Tuning
Fine-tune the retract position precisely during machine setup to perfect pick-and-place alignment without adding external mechanical stops.
Variable Assembly Stops
Set distinct travel endpoints for multiple assembly stations operating on a shared frame, utilizing the 75 mm adjustment range for flexible spacing.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-75S the Right Cylinder?
The 75 mm adjustment range is ideal for machines requiring wide product changeovers, allowing you to dial back the 200 mm nominal stroke down to 125 mm during commissioning rather than swapping out a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, use an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 200 mm stroke, 75 mm adjustment, G3/8 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 200 mm, ensure proper alignment to prevent excessive side loading on the 25 mm rod.
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 SAIJ80AX200-75S FAQ
The nominal stroke is 200 mm, but the rear adjuster allows you to trim the effective travel back by up to 75 mm, resulting in a 125-200 mm usable travel window.
No, the rear adjuster functions only as a travel stop to set the end position, not as a lock or brake. The cylinder cannot hold a load without live air pressure. For true load-holding, use an external rod lock or select the SAIL or BSAI cylinder series.
