About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-40
It features a SUS420J2 stainless steel rod and PT tapered port threads. The built-in rear stopper allows you to dial back the 210mm nominal stroke by up to 40mm, creating a precise 170-210mm usable travel window for exact end-position tuning during commissioning.
This adjustable design eliminates the need to swap cylinders or bolt on external stops during product changeovers. The rear adjuster acts purely as a travel stop to set the end position and relies on the variable air cushion for deceleration; it does not hold the load without live air. Dimensionally interchangeable per ISO 15552, it supports mounting options 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 SAIJ100AX210-40 Is Used
Machine Setup Changeover
Fine-tune the 170-210mm travel window during product line changeovers to accommodate different part sizes without physically replacing the actuator.
Commissioning Calibration
Adjust the stroke during initial machine commissioning to resolve mechanical timing issues or sensor spacing without adding external physical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-40 the Right Cylinder?
Choose this 100mm bore when your application requires heavy thrust in the 7068N range at 0.9 MPa. If your force requirements are lower, stepping down to an 80mm bore yields 4523N, while moving up to 125mm provides 11045N. The 170-210mm adjustable window is ideal for machines needing variable end-stops without cylinder replacement. Because the total travel is 210mm, ensure proper alignment to avoid excessive side loading on the 25mm rod.
For exact ISO 15552 replacement, match the 100mm bore, 210mm stroke, 40mm adjustment, G1/2 port, and mounting set. Note that a plain SAIJ does not hold position without live air; for load-holding requirements, consider the SAIL or BSAI series instead.
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 SAIJ100AX210-40 FAQ
It can deliver up to 801 kgf at 1.0 MPa.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 40mm, providing a usable travel window of 170-210mm from the 210mm nominal stroke. It functions as a travel stop and does not lock or hold the load without continuous air pressure.
