About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-50S
The AirTAC SAIJ100X65-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 15-65 mm from its 65 mm nominal stroke. The piston features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance, and the -S magnet allows seamless integration with CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves.
Unlike a fixed-stroke SAI cylinder, this model allows you to fine-tune the retract end-position directly at commissioning without swapping components or adding external stops. The rear adjuster acts purely as a travel stop to set deceleration and end-limits, meaning it does not hold the load without live air pressure. For load-holding applications without continuous air, consider an SAIL pneumatic lock or BSAI clamp-lock cylinder instead.

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 SAIJ100AX65-50S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 15 to 65 mm during machine commissioning to accommodate changing material thicknesses without mechanical rebuilds.
Product Size Changeover
Quickly adjust the stroke end-point on packaging or handling lines when switching between different product dimensions, ensuring precise stops every time.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-50S the Right Cylinder?
Choose this 100 mm bore when you need high force combined with variable end-stop positioning, such as accommodating different product sizes on a single line. To replace an ISO 15552 cylinder with this SAIJ model, match the 100 mm bore, 65 mm stroke, 50 mm adjustment range, PT tapered port thread, and -S magnet requirement. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments, deliberately omitting FB, CA, CB, and CR options. Since the stroke is under 300 mm, side-load concerns are minimized, though the robust 25 mm rod and M20x1.5 thread handle standard lateral loads effectively.
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 SAIJ100AX65-50S FAQ
The rear adjuster acts as an external stopper that lets you trim the effective travel back by up to 50 mm. This creates a usable stroke window of 15-65 mm, allowing precise end-position tuning without replacing the cylinder.
