About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-75
The AirTAC SAIJ80X95-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. By dialing back the nominal 95 mm travel by up to 75 mm, this model yields a highly flexible 20-95 mm usable stroke window, ideal for dialing in exact end-stops during machine commissioning. It delivers a robust 2513 N push force at 0.5 MPa, matching the standard SAI thrust class.
This SKU is configured with a corrosion-resistant SUS420J2 stainless steel rod (option A) and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts purely as a travel stop and works alongside the standard air cushions; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-75 Is Used
Variable End-Stop Tuning
Dial in the exact 20-95 mm travel distance during machine setup to accommodate varying product lengths without replacing the cylinder.
Product Changeover Systems
Quickly adjust the rear stopper on a conveyor line when switching to a new package size, saving downtime on physical modifications.
Controlled Pressing Operations
Leverage the 2513 N push force to press components, using the fine adjustment to regulate the exact depth of the pressing stroke.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-75 the Right Cylinder?
Choose this 80 mm bore when you need the 2513 N push force at 0.5 MPa (or 4523 N at 0.9 MPa) but require extreme travel flexibility. The 20-95 mm adjustable window lets you handle rapid product-size changeovers on a line without physically swapping cylinders or adding external mechanical stops. If your application needs less force, the 63 mm bore offers 1559 N; if you need more, step up to the 100 mm bore for 3927 N.
For load-holding without continuous air pressure, remember that this SAIJ rear adjuster only sets the end position, so you must look to the SAIL pneumatic lock or BSAI clamp-lock series. Because the stroke is under 300 mm, side-load risks are moderate, but the 25 mm rod and M20x1.5 thread still handle standard guiding duties well. This unit uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80AX95-75 FAQ
The nominal 95 mm stroke can be reduced by up to 75 mm via a rear adjusting screw, giving you a usable travel window of 20 to 95 mm. This allows you to fine-tune the retract end position at commissioning without adding external stops.
At 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 513 kgf.
