Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-30S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX135-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 135mm stroke, G3/8 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 SAIJ80 Adjustable Cylinder SAIJ80AX135-30S
The AirTAC SAIJ80X135-30-S is a double-acting ISO 15552 profile cylinder with a rear mechanical adjuster, letting you dial back the 135 mm nominal stroke by up to 30 mm. This creates a precise 105-135 mm usable travel window for product changeovers without adding external stops.
Equipped with a magnet (-S), it triggers AirTAC CMSE reed and DMSE electronic sensors via the dual-side extruded barrel grooves. The G3/8 PT tapered port handles 30-800 mm/s operating speeds. It uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The rear adjuster acts purely as a travel stop and does not hold loads without live air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80AX135-30S Is Used
Changeover Tuning
Dial in the 105-135 mm travel window during product size transitions on a packaging line, avoiding physical cylinder swaps.
Variable End Stops
Set precise retract positions for machining fixtures, using the rear screw to fine-tune the end-of-stroke location.
Sensor-Ready Actuation
Leverage the built-in magnet with DMSE electronic sensors to confirm the adjusted end position in automated assembly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-30S the Right Cylinder?
The 30 mm adjustment window is ideal for variable end-stop positioning during machine setup. For load-holding without live air, select the SAIL or BSAI series instead, as the SAIJ rear adjuster only sets the travel end. As an ISO 15552 interchangeable replacement, match the 80 mm bore, 135 mm stroke, 30 mm adjust, G3/8 PT port, and SUS420J2 rod. The 25 mm rod and M20x1.5 thread handle high side loads, though long unsupported strokes still need an external guide.
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 SAIJ80 Adjustable Cylinder SAIJ80AX135-30S FAQ
At 0.7 MPa, the push force increases to 3518 N.
A rear screw acts as a mechanical stop, allowing you to shorten the 135 mm stroke by up to 30 mm, creating a 105-135 mm usable travel window. It functions as a stop, not a lock.
