About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-100S
The AirTAC SAIJ100X210-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 110 to 210 mm. The extruded aluminum barrel features sensor grooves on both sides, and because this unit includes the -S magnet, it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection.
This model features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads (G1/2). The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract position, meaning it cannot hold a load without live air pressure. For load-holding requirements without continuous air, an external rod lock or related types like SAIL or BSAI should be specified instead.

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 SAIJ100AX210-100S Is Used
Product Changeovers
Dial in the exact retract distance from 110 to 210 mm during format size changes on a packaging line without changing the physical cylinder mount.
Machine Setup
Fine-tune the end position at commissioning to achieve perfect alignment, using the rear stopper rather than adding external shims or mechanical spacers.
Variable End Stops
Handle multiple part sizes on a single conveyor system by adjusting the effective stroke window to accommodate varying material lengths on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-100S the Right Cylinder?
The 100 mm adjustment range on this 210 mm stroke allows immense flexibility during machine setup or product changeovers, eliminating the need to physically swap cylinders to achieve a shorter effective stroke.
Because the nominal stroke is 210 mm, an external guide should be considered to support the load and prevent excessive side-loading on the rod. When matching this for an ISO 15552 replacement, verify the 100 mm bore, 210 mm stroke, 100 mm adjuster, PT G1/2 ports, and the -S magnet. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR options.
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 SAIJ100 Adjustable Cylinder SAIJ100AX210-100S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to trim the effective stroke back by up to 100 mm, creating a usable travel window between 110 mm and 210 mm. The adjuster is a mechanical stop, not a lock, so the cylinder requires live air to maintain its position.
