About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-20S
It features a SUS420J2 stainless steel rod and a built-in magnet for position sensing. With a nominal 900mm stroke and a 20mm adjustment range, it provides an exact 880-900mm usable travel window for fine-tuning at commissioning.
This extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. The rear screw acts purely as a travel stop to decelerate the end position and does not hold the load without live air pressure. It uses a PT G1/2 port and omits FB, CA, CB, and CR mounts, utilizing a reduced ISO 15552 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 SAIJ100AX900-20S Is Used
Product Changeover
Dial in the 880-900mm travel window during line format changes to accommodate different product lengths without mechanical rebuilds.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to perfect the deceleration point of heavy 3927N loads.
Long-Stroke Assembly
Execute extended 900mm linear movements in automated assembly lines while relying on the built-in magnet for DMSE sensor feedback.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-20S the Right Cylinder?
The 20mm adjustment window allows variable end-stops for product changeovers without swapping the cylinder or adding external stops. For load-holding without live air, select a SAIL or BSAI cylinder instead, as this adjuster is not a lock.
Because the 900mm stroke is long, an external guide is recommended to prevent excessive side-loading on the 25mm rod. To match this ISO 15552 replacement exactly, specify the 100mm bore, 900mm stroke, 20mm adjust, PT G1/2 port, -S magnet, and SUS420J2 rod material.
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 SAIJ100AX900-20S FAQ
At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the effective travel by up to 20mm, creating an 880-900mm usable window. It acts as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
