About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-10
The AirTAC SAIJ80X700-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 2513N push force at 0.5 MPa and incorporates a SUS304 stainless steel piston rod for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with a 10mm adjustment range, this model allows you to fine-tune the effective travel down to a 690mm minimum, creating a 690-700mm usable window. This built-in stopper lets you dial in the exact retract position during commissioning without adding external stops. The adjuster acts only as a travel limiter and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-10 Is Used
Machine Changeover
Quickly dial in the 690-700mm retract position during product size transitions without swapping the cylinder or adding external stopper blocks.
Variable End-Stop Diverter
Fine-tune the exact retraction point of a diverter arm on a packaging line to handle different carton widths on the fly.
Commissioning Calibration
Use the 10mm rear adjustment screw to precisely set the tooling end-position during initial machine commissioning, compensating for mechanical tolerances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-10 the Right Cylinder?
Choose this 80mm bore when the 50mm bore (982N push at 0.5 MPa) lacks the necessary thrust for your heavier fixtures. The adjustable stroke is highly beneficial for machine setups requiring precise end-position tuning during product changeovers, serving as a more flexible alternative to a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
Because this cylinder features a long 700mm stroke, the 25mm rod and M20x1.5 thread provide robust support, but an external guide is strongly recommended to prevent excessive side-loading. It is dimensionally interchangeable per ISO 15552 and comes with PT tapered ports. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX700-10 FAQ
At a 0.5 MPa operating pressure, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster allows you to shorten the 700mm nominal stroke by up to 10mm, providing a usable travel window of 690-700mm. It acts as a mechanical stop to fine-tune the retract position and does not lock the load without air pressure.
