About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-10S
The AirTAC SAIJ80X135-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This specific SKU trims the 135mm nominal stroke back by up to 10mm, creating a precise 125-135mm usable travel window for exact end-position tuning.
This configuration includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and a PT tapered port thread. The integrated magnet (-S) supports position sensing with AirTAC CMSE reed and DMSE solid-state switches. The rear adjustment screw functions purely as a travel stop to dial in the retract distance during commissioning; it is not a lock, so the cylinder cannot hold a load 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 SAIJ80AX135-10S Is Used
End-Position Tuning
Dial in the exact retract distance within the 125-135mm window during machine commissioning to perfect product handling without external stops.
Product Changeover
Quickly adjust the stroke stop on the fly when switching between different package sizes or tooling on the same production line.
Fixture Clamping
Apply up to 2513N of clamping force at 0.5 MPa while using the rear screw to compensate for minor variations in workpiece dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-10S the Right Cylinder?
The 10mm adjustable stroke is selected over a fixed-stroke SAI when you need variable end stops or fine-tuning during machine setup and product changeover without adding external stops. For any load-holding requirements without continuous air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster only sets the travel end.
To match this ISO 15552 cylinder for a replacement, verify the 80mm bore, 135mm stroke, 10mm adjustment range, PT G3/8 port, and the -S magnet. It uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Operating speed ranges from 30-800 mm/s.

- ✓ 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 SAIJ80AX135-10S FAQ
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke from its 135mm nominal length by up to 10mm, providing a usable travel window of 125-135mm. It allows precise end-position tuning during setup but does not lock or hold the load without live air pressure.
