About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX210-100S
The AirTAC SAIJ80X210-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The defining trait of this SKU is its 100mm adjustment range, which creates a highly versatile 110-210mm usable travel window for fine-tuning end positions.
This model uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and pairs with PT tapered ports. Because it is an extruded aluminum profile cylinder, it provides dual sensor grooves compatible with AirTAC CMSE reed and DMSE electronic switches. The rear screw acts purely as a travel stop to dial in the exact retract distance during commissioning without requiring external stops.

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 SAIJ80AX210-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 110-210mm window during machine setup, allowing precise positioning of parts without adding external mechanical stops.
Product Size Changeover
Quickly adjust the cylinder's effective stroke on the line when switching between different product lengths, minimizing downtime and avoiding cylinder swaps.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX210-100S the Right Cylinder?
Selecting this 80mm bore cylinder makes sense when your machine requires high thrust but variable end-stops across different product sizes. If your application needs less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa, whereas moving up to a 100mm bore provides 3927N. This adjustable model is chosen over a fixed-stroke SAI when you need on-the-fly end-position tuning rather than machining new hard stops.
For an exact ISO 15552 replacement, match the 80mm bore, 210mm stroke, 100mm adjuster, G3/8 port, and the -S magnet requirement. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since the nominal stroke is 210mm, ensure adequate external guiding to handle side loads. The rear adjuster is a stop, not a lock; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80AX210-100S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 110-210mm from the 210mm nominal stroke, letting you set the exact end position at commissioning. The adjuster is a stop, not a lock.
