About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-50
The AirTAC SAIJ100X65-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning without external stops. It provides a usable travel window of 15 to 65 mm, letting you dial back the 65 mm nominal stroke by up to 50 mm during machine commissioning or product changeover.
This SKU is configured with a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G1/2) and lacks a piston magnet, meaning it is not compatible with AirTAC CMSE or DMSE sensors without modification. The rear adjuster acts purely as a travel stop to set deceleration limits and does not hold the load without live air pressure.

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 SAIJ100AX65-50 Is Used
Product Changeover
Quickly dial back the retract stroke by up to 50 mm to accommodate different package lengths on a packaging line without changing the cylinder.
End-Stop Tuning
Fine-tune the final end position during machine commissioning to achieve exact 15 mm positioning limits without adding external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-50 the Right Cylinder?
Choose this adjustable-stroke SAIJ over a fixed SAI cylinder when you anticipate product size changes or need to fine-tune the retract distance during setup without swapping hardware.
Because this is a short 65 mm stroke, side-loading risks are minimal, but always ensure the rod is aligned with the load to prevent premature seal wear. Remember that the rear adjuster is a stop, not a locking device; if you need to hold a load vertically without continuous air pressure, integrate an external rod lock or select a SAIL or BSAI clamping cylinder. This model is dimensionally interchangeable per ISO 15552 and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX65-50 FAQ
The 50 mm adjustment screw allows you to trim the 65 mm nominal stroke, resulting in a usable travel window of 15 to 65 mm.
No, the rear adjuster functions only as a travel stop to set the end position and works with the air cushion for deceleration. It does not lock or hold the load without live air; for load-holding, consider a SAIL or BSAI cylinder.
