About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-10S
The AirTAC SAIJ80X700-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 690-700 mm usable travel window, allowing you to dial back the 700 mm nominal stroke by up to 10 mm during commissioning. The 80 mm bore delivers robust thrust, yielding 3518 N push force at 0.7 MPa and a maximum of 513 kgf at 1.0 MPa.
This variant features an SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet (-S) for position sensing. It works seamlessly with AirTAC CMSE reed switches and DMSE solid-state electronic sensors fitted into the extruded aluminum barrel's dual-side grooves. The standard PT tapered ports (G3/8) and adjustable air cushions at both ends ensure reliable operation across the 30-800 mm/s speed range.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-10S Is Used
Machine Changeover
Dial in the exact 690 to 700 mm retract position during product size changes without physically swapping the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the travel end during initial commissioning to absorb mechanical tolerances and achieve precise seating against the workpiece.
Long-Stroke Assembly
Leverage the 80 mm bore's 3518 N push force at 0.7 MPa to drive heavy assembly presses over a 700 mm travel distance.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-10S the Right Cylinder?
Choose this 80 mm bore when an application requires more thrust than the 63 mm option (which provides 2182 N at 0.7 MPa) but does not demand the massive output of the 100 mm class. The adjustable stroke is ideal for variable end-stops or machine changeovers, letting you fine-tune the retract position without swapping cylinders or adding external stops. For replacing an ISO 15552 cylinder, match the 80 mm bore, 700 mm stroke, 10 mm adjustment, PT G3/8 port, and -S magnet.
Because the nominal stroke is 700 mm, the M20x1.5 rod thread and 25 mm rod diameter must be evaluated for side-load risks; long unsupported strokes require an external guide to prevent binding. Remember that the rear adjuster is a travel stop, not a lock—the SAIJ will not hold a load without live air. For true load-holding without pressure, consider the SAIL or BSAI series. Mounting options include 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 SAIJ80AX700-10S FAQ
At 0.7 MPa it provides 3518 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 513 kgf of push force.
A rear external screw acts as a stopper, allowing you to shorten the effective stroke by up to 10 mm. This creates a 690-700 mm adjustable travel window, but it only sets the end position; it does not lock the load without live air pressure.
