About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-100S
The AirTAC SAIJ80X750-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window from 650 to 750 mm. The piston rod is constructed from SUS420J2 stainless steel (code A), offering excellent resistance to wear and corrosion in demanding environments.
Equipped with a magnet for position sensing, this unit supports AirTAC CMSE reed and DMSE electronic solid-state switches mounted into the dual-side sensor grooves on the extruded aluminum barrel. It uses PT tapered G3/8 ports and relies on adjustable air cushions at both ends to decelerate the load smoothly over the long 750 mm stroke.

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 SAIJ80AX750-100S Is Used
Variable End-Stop Machining
Dial in the exact clamping position on machining fixtures by adjusting the rear stopper from 650 to 750 mm without changing the cylinder body.
Product Changeover Diverters
Quickly adapt conveyor sorting diverters to different package lengths by turning the rear adjuster to shift the retract stroke end-point.
Long-Stroke Assembly Presses
Handle heavy component seating over a 750 mm travel distance, using the SUS420J2 stainless rod and air cushions to manage impact.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-100S the Right Cylinder?
The 100 mm adjustment range is ideal for product changeovers on a line, allowing operators to set variable end-stops without physically swapping the cylinder or adding external mechanical stops. Because the nominal stroke is 750 mm, an external guide rail is highly recommended to prevent excessive side-loading on the extended rod.
For load-holding applications, remember that the rear adjuster is strictly a travel stop, not a locking device; this cylinder will not hold its position without live air pressure. For true fail-safe holding, consider the SAIL or BSAI series. To replace an ISO 15552 cylinder, match the 80 mm bore, 750 mm stroke, 100 mm adjustment, PT G3/8 port, and -S magnet, noting that SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB, CA, CB, and CR).
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 SAIJ80AX750-100S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 100 mm, providing a usable travel window of 650 to 750 mm for fine-tuning the end position at commissioning.
