About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-100
The AirTAC SAIJ80X175-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 75-175 mm, allowing you to dial back the nominal 175 mm stroke by up to 100 mm.
This model features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic sensors. The rear adjustment screw acts as a travel stop for fine-tuning end positions at commissioning, but it does not hold the load 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 SAIJ80AX175-100 Is Used
Product Changeovers
Quickly adjust the end-of-stroke position by up to 100 mm when switching machinery to handle different product lengths on the same line.
Commissioning Calibration
Fine-tune the 175 mm stroke down to a 75 mm travel window during machine setup to perfect positioning without adding external mechanical stops.
Variable End-Stop Actuation
Use the rear screw to set precise retract positions for multi-stage forming or pressing tasks requiring adaptable travel distances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-100 the Right Cylinder?
If your setup needs less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, while moving up to a 100 mm bore provides 3927 N. The 100 mm adjustment range is ideal for machines processing varying product sizes, letting operators change the end-stop position on the fly without swapping cylinders or adding external stops.
This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Because the 175 mm stroke is under 300 mm, side-load risks are moderate, but the 25 mm rod and M20x1.5 thread still require alignment. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is a stop, not a lock.
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 SAIJ80AX175-100 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 175 mm down to 75 mm. This creates a 75-175 mm adjustable window for fine-tuning the retract end position at commissioning without changing the cylinder.
