About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX185-100
The AirTAC SAIJ80X185-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 85 to 185 mm, allowing you to dial back the nominal stroke by up to 100 mm during machine setup.
This model incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts strictly as a travel stop to fine-tune the end position without swapping the cylinder, not as a load-holding lock.

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 SAIJ80AX185-100 Is Used
Variable End-Stop Machining
Dial in the exact clamping depth for different material thicknesses on a single fixture using the 85-185 mm travel window.
Product Changeover Diverter
Quickly reposition a pneumatic diverter gate to accommodate new package lengths on a packaging line without changing cylinders.
Commissioning Stroke Tuning
Fine-tune the retract end-position during initial machine commissioning to clear mechanical interference without adding external stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX185-100 the Right Cylinder?
The 100 mm adjustment window lets you reconfigure the travel distance on the fly, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If you need less force, stepping down to a 63 mm bore yields 1559 N, while moving up to a 100 mm bore provides 3927 N.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 185 mm nominal stroke, 100 mm adjustment range, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the nominal stroke is under 300 mm, external side-load guides are less critical than with longer strokes, but the 25 mm rod and M20x1.5 thread still handle standard operational loads. For true load-holding without live air pressure, this cylinder is insufficient; you must specify a SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
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 SAIJ80AX185-100 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw lets you shorten the effective travel from the 185 mm nominal stroke down to as little as 85 mm, creating an 85-185 mm adjustable window. It acts as a mechanical stop for end-position tuning and does not hold the load without live air pressure.
