About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX80-40
The AirTAC SAIJ100X80-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 40 to 80 mm, allowing you to dial back the nominal 80 mm stroke by up to 40 mm during commissioning.
This specific SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches, though this base configuration omits the internal magnet. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops.

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 SAIJ100AX80-40 Is Used
Product Changeover Dials
Fine-tune the 40 to 80 mm travel window on the fly to accommodate varying product lengths without swapping out the entire cylinder assembly.
End-Stop Calibration
Use the rear adjusting screw to precisely set the retracted end position during machine commissioning, preventing over-travel damage.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX80-40 the Right Cylinder?
Choose this 100 mm bore when 50 mm bore thrust (982 N at 0.5 MPa) is insufficient but you want to avoid the larger 160 mm frame. The 40 mm adjustment range is ideal for product changeovers where the precise end-of-stroke contact point varies. Since the nominal stroke is 80 mm, no external guide is required for side-load support.
For load-holding without continuous air pressure, note that the rear adjuster and air cushions do not function as a lock; consider the SAIL or BSAI series instead. To match this exact unit, specify: 100 mm bore, 80 mm stroke, 40 mm adjustment, PT port, SUS420J2 rod, no magnet, and SAIJ mounting (Basic, FA, LB, TC, FTC, TCM1, TCM2 — omitting FB/CA/CB/CR). It is dimensionally interchangeable per ISO 15552.
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 SAIJ100AX80-40 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 80 mm down to 40 mm. This creates a 40 to 80 mm usable travel window for fine-tuning end positions at commissioning.
It can deliver up to 801 kgf at its maximum 1.0 MPa pressure.
