About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-20S
The AirTAC SAIJ100X100-20-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial back the effective travel to a precise 80-100 mm window without adding external stops. It delivers substantial thrust, pushing 3927 N and pulling 3681 N at 0.5 MPa. This bore uses a G1/2 port and a robust 25 mm rod with an M20x1.5 thread to handle high side loads.
This specific SKU features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop for end-position tuning at commissioning; it does not lock or hold the load without live air pressure. For load-holding needs, consider the SAIL or BSAI series.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100AX100-20S Is Used
End-Position Tuning
Fine-tune the retract stroke within the 80-100 mm window during commissioning to perfectly align heavy clamping fixtures without machining external stop blocks.
Product Changeover
Quickly adapt automated machinery for different product sizes by adjusting the rear stopper screw, minimizing downtime between production runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-20S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring a variable end-stop during product changeovers. When matching an ISO 15552 replacement, verify the 100 mm bore, 100 mm nominal stroke, 20 mm adjustment, PT tapered port threads, and the -S magnet option.
Because the nominal stroke is 100 mm, an external guide is not strictly required for preventing rod buckling, but the 25 mm rod and M20x1.5 thread provide excellent rigidity if moderate side loads exist. Remember that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets.
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 SAIJ100AX100-20S FAQ
The operational speed range is 30-800 mm/s.
The rear adjuster screw lets you shorten the 100 mm nominal stroke by up to 20 mm, creating an 80-100 mm usable travel window. It functions as a mechanical stop for end-position tuning and does not hold the load without live air pressure.
