About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-75
The AirTAC SAIJ80X175-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 175 mm nominal stroke to anywhere within a 100-175 mm usable travel window. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This configuration uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position during commissioning; it does not lock the load without live air pressure. Pneumatic cushioning at both ends absorbs kinetic energy, while the PT (tapered) G3/8 ports handle the 30-800 mm/s operating 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 SAIJ80AX175-75 Is Used
Machine Changeover
Quickly reconfigure the retract distance within the 100-175 mm window to accommodate different product sizes on the same line without replacing hardware.
End-Position Tuning
Fine-tune the exact stopping point during commissioning using the rear screw, eliminating the need to machine external spacers for the 80 mm bore.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-75 the Right Cylinder?
If your process demands less force, stepping down to a 63 mm bore yields 1559 N; if you need more clamping power, a 100 mm bore provides 3927 N. Because this SKU lacks the -S magnet option, it cannot host CMSE or DMSE electronic sensors without modification.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 175 mm stroke, 75 mm adjustment range, PT G3/8 port thread, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR brackets. For any load-holding requirements without continuous air pressure, specify a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is only a travel stop. Although the 175 mm stroke is under the 300 mm threshold, always ensure adequate external guidance to protect the 25 mm rod thread from excessive side-loading.
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 SAIJ80AX175-75 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm, providing a usable travel window of 100 to 175 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
