About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-10
The AirTAC SAIJ80X700-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 690 to 700 mm usable travel window, allowing precise end-position tuning without adding external stops. Built with a SUS420J2 stainless steel rod and PT tapered ports, it delivers 2513 N of push force at 0.5 MPa, scaling up to 4523 N at 0.9 MPa.
This adjustable-stroke design is ideal for commissioning and product changeovers, letting you dial in the retract end-position on the fly. The rear adjuster functions strictly as a travel stop, not a lock, meaning it cannot hold a load without live air pressure. For load-holding without continuous air, you would need to specify an SAIL or BSAI variant.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-10 Is Used
Long-Stroke Machine Setup
Dial in the 690-700 mm travel window during commissioning to perfectly align long-stroke clamping or lifting motions without machining custom spacers.
Product Changeover
Quickly adjust the retract end-position by up to 10 mm when switching conveyor line product sizes, saving downtime on the factory floor.
End-Position Tuning
Fine-tune the rear stopper to compensate for mechanical wear or slight misalignment over the cylinder's 700 mm travel cycle.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-10 the Right Cylinder?
Choose this 80 mm bore when you need more thrust than the 50 mm bore offers (982 N push at 0.5 MPa) but want to avoid the larger footprint of the 100 mm bore. The 10 mm adjustment range is perfect for fine-tuning a long 700 mm travel distance. Because the stroke is 700 mm, an external guide is highly recommended to prevent excessive side-loading on the 25 mm rod and M20x1.5 rod thread.
To match this cylinder as an ISO 15552 replacement, specify an 80 mm bore, 700 mm stroke, 10 mm adjustment, PT port threads, and no magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If you need position feedback, note that this unit lacks a magnet, so CMSE reed and DMSE electronic sensors cannot be used without upgrading to an -S model.
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 SAIJ80AX700-10 FAQ
At 0.5 MPa, the 80 mm bore provides 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster allows you to shorten the 700 mm nominal stroke by up to 10 mm, creating a 690-700 mm usable travel window. It acts as a mechanical stop and does not lock the load without air pressure.
