About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-75S
The AirTAC SAIJ80X95-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 95 mm stroke by up to 75 mm. This creates a highly flexible usable travel window from 20 mm to 95 mm, perfect for adapting end positions on the fly. It delivers a robust 2513 N push force at 0.5 MPa and 3518 N at 0.7 MPa.
This variant features an SUS420J2 stainless steel piston rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides dual sensor grooves, while the PT G3/8 ports ensure high flow. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-75S Is Used
Product Changeover
Dial in new retract end positions instantly when packaging line dimensions change, utilizing the 20-95 mm travel window to handle varied product sizes without swapping hardware.
Machine Setup
Fine-tune the final end position during commissioning using the rear stopper, eliminating the need to bolt on external stops or recalculate complex mechanical linkages.
Variable End Stops
Adjust the effective stroke on the fly for testing different press depths or clamping forces, relying on the 3518 N push force at 0.7 MPa to execute precise movements.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-75S the Right Cylinder?
Choose this 80 mm bore when your application requires substantial thrust—stepping up from a 50 mm bore gives you 982 N at 0.5 MPa, while stepping down to a 63 mm bore provides 1559 N. The SAIJ80X95-75-S is selected specifically when you need extreme stroke variability, as the 75 mm adjustment range lets you fine-tune the retract end across a 20 to 95 mm window during commissioning or product changeovers without swapping cylinders.
For load-holding without live air pressure, note that the rear adjuster is a travel stop, not a lock; you would need an external rod lock or a related type like the BSAI clamp-lock. This model uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The 25 mm rod and M20x1.5 thread handle high side loads, though long unsupported strokes still require external guides.
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 SAIJ80AX95-75S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the nominal 95 mm stroke by up to 75 mm, creating a usable travel window of 20 to 95 mm. It functions as a mechanical stop and does not lock the load without air pressure.
