Airtac SAIJ100 Adjustable Cylinder SAIJ100AX80-20
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX80-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 80mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX80-20
The AirTAC SAIJ100X80-20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 60-80mm usable travel window by allowing you to trim up to 20mm from the 80mm nominal stroke. The piston rod uses SUS420J2 stainless steel (code A), and the PT tapered port threads ensure a tight, reliable pneumatic connection.
This adjustable-stroke design allows you to fine-tune the end position at commissioning without swapping the entire cylinder or adding external stops. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, meaning it will not hold a load without live air pressure. You can mount CMSE reed or DMSE electronic sensors directly into the dual-side barrel grooves, though this specific SKU omits the internal magnet.

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 SAIJ100AX80-20 Is Used
Machine Changeover
Dial in the 60-80mm travel window during product size changes on a packaging line without disassembling the actuator.
End-Position Tuning
Fine-tune the retract stop during commissioning to perfect a pressing or clamping operation without external spacers.
Variable End Stops
Adjust the effective stroke on automated assembly equipment to accommodate varying part heights on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX80-20 the Right Cylinder?
The adjustable 20mm end-stop is ideal for machine setups requiring variable end positions during product changeovers, avoiding the need to maintain multiple fixed-stroke SAI cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. To match this SKU exactly when replacing an ISO 15552 cylinder, specify the 100mm bore, 80mm stroke, 20mm adjustment, PT port thread, SUS420J2 rod, and no magnet.
Because the 80mm stroke is relatively short, side-load stress on the M20x1.5 rod thread is minimal, but you must always guide the load externally. If your process requires true load-holding without continuous air pressure, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead, as the SAIJ adjuster cannot hold position.
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 SAIJ100AX80-20 FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 20mm, providing a usable stroke window of 60-80mm. It acts as a mechanical stop to tune the end position during commissioning, but it is not a lock and cannot hold a load without live air pressure.
At 0.9 MPa, the push force increases to 7068N.
