About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-30S
The AirTAC SAIJ100X210-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 180 to 210 mm. This bore size features a 25 mm piston rod, a G1/2 port, and 36 mm cushions at both ends to manage heavy kinetic energy.
This configuration includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and ships with a magnet (-S) for position sensing. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it is not a locking device. For load-holding without live air pressure, an external rod lock or related SAIL cylinder is required.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100AX210-30S Is Used
Machine Setup Changeover
Dial in the 180-210 mm travel window during product size changes to set exact retract positions without swapping hardware.
Commissioning Fine-Tuning
Trim the stroke by up to 30 mm on-site to resolve minor mechanical interference or timing issues during initial machine bring-up.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-30S the Right Cylinder?
The adjustable stroke is chosen over a fixed SAI model when you need precise end-position tuning during machine setup or product changeover without adding external stops. Because the stroke is 210 mm, which is over 300 mm, standard side-load guidance is acceptable, but ensure external guides support any heavy lateral loads.
To match this exact ISO 15552 replacement, verify the 100 mm bore, 210 mm nominal stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors housed in the dual-side barrel grooves.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100AX210-30S FAQ
The maximum push force is 7068 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 210 mm nominal stroke by up to 30 mm, creating a usable travel window of 180 to 210 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
