About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX70-10S
The AirTAC SAIJ80X70-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability eliminates the need to swap cylinders or add external stoppers during machine commissioning or product changeovers.
This configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and utilizes PT tapered port threads. It is factory-fitted with a magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear stopper functions strictly as a travel end-point deceleration setter, not a load-holding lock.

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 SAIJ80BX70-10S Is Used
End-Stop Calibration
Dial in the exact 60-70mm retraction point during machine commissioning without swapping out physical components or shimming mounts.
Product Changeover
Quickly adjust the stroke by up to 10mm on packaging lines when running a slightly shorter product profile.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX70-10S the Right Cylinder?
The adjustable 60-70mm window is ideal for dialing in precise strokes without mechanical rework.
Because the nominal stroke is 70mm, external side-load guides are less critical than on longer strokes, though the 25mm rod and M20x1.5 thread naturally handle high side loads. To replace an ISO 15552 cylinder, match the 80mm bore, 70mm stroke, 10mm adjustment, PT ports, and the -S magnet. Remember that the SAIJ rear adjuster and air cushions only set travel ends; they do not hold loads without live air. For fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder, or an external rod lock.
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 SAIJ80BX70-10S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 10mm. This creates a 60-70mm adjustable travel window, allowing you to fine-tune the end position at commissioning without changing the cylinder.
At 0.7 MPa, the push force increases to 3518N.
