About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-10S
The AirTAC SAIJ80X400-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 2513N push force at 0.5 MPa and a usable travel window of 390-400mm, letting you dial in the exact retract end-position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic solid-state switches.
This SKU is equipped with a SUS420J2 stainless steel piston rod (code A) and PT tapered G3/8 ports. The 25mm rod diameter and M20x1.5 thread provide high rigidity, but with a 400mm stroke, you should use an external guide to prevent side-load damage. The rear adjuster acts purely as a travel stop for fine-tuning, not a load-holding lock.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-10S Is Used
Product Changeover Stops
Dial in the 390-400mm retract position during line changeovers to accommodate different product lengths without swapping out the entire actuator.
Commissioning Fine-Tuning
Use the 10mm rear adjustment screw to perfectly set the end-of-stroke position during initial machine setup, eliminating the need for external mechanical stops.
Variable Push-Off Distances
Adjust the travel window on the fly for pneumatic pusher arms that need to handle varying package sizes on a moving conveyor line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-10S the Right Cylinder?
Choose this 80mm bore if your application requires more thrust than a 63mm cylinder (1559N at 0.5 MPa) but less than a 100mm bore (3927N). An adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, offering on-the-fly fine-tuning that a fixed-stroke SAI cylinder cannot match. To replace an ISO 15552 cylinder, match the 80mm bore, 400mm stroke, 10mm adjustment, PT G3/8 port, and basic mounting interface.
Because this is a 400mm stroke, supporting the load with an external guide is critical to prevent excessive side-loading on the rod. Remember that the rear adjuster and air cushions only decelerate the travel end; a plain SAIJ does not hold its load without live air. For true fail-safe load holding, select a SAIL pneumatic lock or BSAI clamp-lock 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 SAIJ80AX400-10S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. At the maximum pressure of 1.0 MPa, the push force reaches 5026N.
The rear adjuster screw allows you to shorten the nominal 400mm stroke by up to 10mm, creating a usable travel window of 390-400mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
