About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-30S
The AirTAC SAIJ80X110-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N of push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed within the dual-side sensor grooves.
With a nominal 110mm stroke and a 30mm adjustment range, this model provides an exact 80-110mm usable travel window. This built-in rear stopper allows you to fine-tune the retract end position during commissioning without adding external stops. The extruded aluminum barrel design omits the FB, CA, CB, and CR mounting options, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-30S Is Used
Changeover Calibration
Dial in the 80-110mm retract position during product family changeovers without physically swapping the cylinder or repositioning hard stops.
Variable End Positioning
Achieve precise lower-end tuning for pressing or forming operations where the exact bottoming point needs micro-adjustments on the fly.
Heavy-Duty Handling
Leverage the 2513N push force at 0.5 MPa to move substantial payloads while retaining the flexibility to alter the stroke endpoint per application.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-30S the Right Cylinder?
Select this 80mm bore cylinder when an application requires substantial force but variable end-stops, such as accommodating different product sizes on a single line. If your process demands less thrust, stepping down to a 63mm bore yields 1559N of push force at 0.5 MPa. Conversely, moving up to a 100mm bore provides 3927N. Because the 110mm stroke is below the 300mm threshold, side-load stress on the 25mm rod and M20x1.5 thread is minimal, though external guiding remains good practice for heavy loads.
This SKU is configured with standard carbon steel rod material and PT tapered port threads for the G3/8 ports. Remember that the rear adjuster functions strictly as a travel stop, not a locking device; the cylinder cannot hold a load without live air pressure. For fail-safe load holding without continuous air, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ80X110-30S FAQ
The rear adjuster acts as an external stopper that trims the effective travel. For this model, you can shorten the 110mm nominal stroke by up to 30mm, creating an adjustable 80-110mm travel window to fine-tune the end position during setup.
At 0.5 MPa operating pressure, it provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
