About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-40S
The AirTAC SAIJ100X210-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 170 to 210 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This adjustable-stroke design allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The rear screw acts strictly as a travel stop for deceleration, not a load-holding lock; for position retention without live air pressure, consider the SAIL or BSAI series. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX210-40S Is Used
Machine Setup Tuning
Dial in the exact 170-210 mm end position during commissioning without swapping out the physical cylinder or bolting on external stops.
Product Size Changeover
Quickly adjust the retract stop on a conveyor line when processing different product lengths, saving valuable changeover time.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-40S the Right Cylinder?
The 40 mm adjustment range is ideal for product changeovers on a line, letting operators dial in the exact end-stop without mechanical modifications. Because the 210 mm stroke exceeds 300 mm is not the case here, an external guide is less critical, but the 25 mm rod and M20x1.5 thread handle substantial side loads well.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 100 mm bore, 210 mm stroke, 40 mm adjuster, PT tapered ports, and the -S magnet for sensor readiness. For fixed travel without the adjuster, the standard SAI series is the alternative.
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 SAIJ100AX210-40S FAQ
The rear adjuster allows you to shorten the nominal 210 mm stroke by up to 40 mm, creating a usable travel window of 170 to 210 mm. This adjuster acts as a mechanical stop for end-position tuning and does not hold the load without live air pressure.
