About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-100S
The AirTAC SAIJ80X210-100-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 110 to 210 mm, letting you dial back the nominal stroke by up to 100 mm during commissioning without adding external stops.
This variant ships with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet (-S) for position sensing. The 25 mm rod and M20x1.5 thread provide a robust interface that handles high side loads, while the extruded aluminum barrel integrates sensor grooves on both sides. You can fit AirTAC CMSE reed or DMSE electronic sensors directly along the body, and the standard PT (tapered) G3/8 ports ensure straightforward pneumatic plumbing.

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 SAIJ80BX210-100S Is Used
Variable Product Changeover
Dial the retract position back by up to 100 mm to instantly accommodate different package lengths on a packaging line without changing the cylinder.
Machine Setup Calibration
Fine-tune the end-stop during commissioning to achieve perfect pressing depth, avoiding the need to machine custom external spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-100S the Right Cylinder?
Choose this 80 mm bore when an application requires substantial force—stepping down to a 63 mm bore drops the 0.5 MPa push thrust to 1559 N, whereas moving up to a 100 mm bore yields 3927 N. The 100 mm adjustment range is ideal for machines processing variable product sizes, allowing you to fine-tune the retract end-position on the fly instead of physically swapping out a fixed-stroke SAI cylinder. Because the stroke extends to 210 mm, you should incorporate an external guide to prevent excessive side-loading on the rod.
When specifying a replacement, verify the 80 mm bore, 210 mm nominal stroke, 100 mm adjustment range, PT G3/8 ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop and does not function as a lock; the SAIJ will not hold a load without live air pressure. For true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ80BX210-100S FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke from 210 mm down to as little as 110 mm. This provides a 100 mm tuning window to set the exact retract end-position without swapping the cylinder.
At 0.9 MPa, the push force increases to 4523 N.
