About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX375-10S
The AirTAC SAIJ80X375-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 365 to 375 mm. Delivering a robust 3518 N push force at 0.7 MPa, it handles heavy-duty positioning with ease. The barrel is extruded aluminum, featuring sensor grooves on both sides for straightforward switch placement.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, ensuring reliable position feedback. The piston rod uses SUS420J2 stainless steel for superior corrosion resistance, while the PT tapered port threads guarantee a tight, leak-free pneumatic connection. The rear adjuster acts strictly as a travel stop to decelerate the load, not a lock, meaning live air pressure is required to hold position.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX375-10S Is Used
Long-Stroke Positioning
Ideal for moving heavy jigs across a 375 mm span, using the 10 mm rear stopper to dial in the exact retract distance without adding physical spacers.
Machine Changeover
Quickly adapt automated lines to new product lengths by turning the rear adjuster, shifting the effective travel window between 365 and 375 mm.
Heavy Assembly Pressing
Applies up to 3518 N of push force at 0.7 MPa for seating components, while DMSE electronic sensors confirm the end of stroke.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX375-10S the Right Cylinder?
Choose this 80 mm bore when an application demands more thrust than a 63 mm bore, which provides 2182 N at 0.7 MPa, but does not require the 5497 N push force of a 100 mm class. The 10 mm adjustable range is selected for applications needing minor end-position tuning during commissioning or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. Because the stroke is 375 mm, an external guide is recommended to prevent rod side-loading and premature seal wear over long unsupported travel.
For exact ISO 15552 replacement matching, verify the 80 mm bore, 375 mm stroke, 10 mm adjustment, PT port thread, and the -S magnet option. If your machine requires true load-holding without continuous air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock series instead of relying on the standard air cushion.
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 SAIJ80AX375-10S FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder generates a push force of 3518 N and a pull force of 2268 N. It can deliver up to 4523 N push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a usable travel window of 365 to 375 mm. This stopper decelerates the travel end but does not lock the load without live air pressure.
