About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-10S
The AirTAC SAIJ80X150-10-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. The built-in rear stopper allows you to trim the nominal 150mm travel back by up to 10mm, creating a precise 140-150mm usable window for exact end-position tuning during commissioning.
This adjustable design eliminates the need to swap cylinders or bolt on external stops when dialing in a machine sequence. It includes self-lubricating variable air cushions at both ends to manage impact loads and features dual sensor grooves for CMSE and DMSE switches. The rear adjuster acts purely as a travel stop and deceleration point, meaning it will not 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 SAIJ80BX150-10S Is Used
Machine Setup Tuning
Dial in the exact 140-150mm end-stop position during initial commissioning without machining new mounting plates or swapping cylinders.
Product Changeover
Quickly adjust the stroke by up to 10mm on a packaging line when running a slightly shorter product format, minimizing downtime.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-10S the Right Cylinder?
The 10mm adjustment range is perfect for applications requiring slight end-position corrections during product changeovers. For holding a load without continuous air pressure, this cylinder is not suitable; you should explore an AirTAC SAIL or BSAI locking cylinder instead.
When replacing an ISO 15552 cylinder, match the 80mm bore, 150mm stroke, 10mm adjustment, G3/8 PT tapered ports, and the -S magnet. The SAIJ utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Because the stroke is under 300mm, side-load risks are moderate, but the 25mm rod handles typical lateral forces well.
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 SAIJ80BX150-10S FAQ
An external adjusting screw at the rear acts as a stopper, allowing you to shorten the effective stroke by up to 10mm. This creates a 140-150mm travel window for fine-tuning the retract end position without changing the cylinder.
At 0.9 MPa, the push force increases to 4523N.
