About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX40-10S
The AirTAC SAIJ80X40-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 2513N push force at 0.5 MPa. It features an extruded aluminum barrel with sensor grooves on both sides and a SUS420J2 stainless steel piston rod. By turning the rear adjusting screw, you can fine-tune the effective travel within a 30-40 mm usable window without adding external stops.
This adjustable-stroke design is built for precise end-position tuning during machine commissioning or product changeovers. The PT tapered port threads match the G3/8 air supply, while the integrated magnet supports CMSE reed and DMSE solid-state sensors for exact position feedback. Remember that the rear adjuster acts strictly as a travel stop, not a load-holding lock; for position retention without live air, explore SAIL or BSAI models.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX40-10S Is Used
Machine Changeovers
Dial in the exact 30-40mm end-position during product size changes without swapping the entire cylinder or repositioning external physical stops.
Commissioning Setup
Fine-tune the retract stroke on the fly during initial machine setup to absorb mechanical tolerances and achieve perfect alignment.
Variable End Stops
Create a precise, repeatable travel limit for clamping or pressing tasks where the exact endpoint needs occasional micro-adjustments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX40-10S the Right Cylinder?
Choose this 80mm bore when you need higher thrust than a 63mm cylinder (which provides 1559N at 0.5 MPa) but want to avoid the bulk of a 100mm bore. The adjustable 30-40 mm travel window is perfect for applications requiring variable end-stops, offering setup flexibility that a fixed-stroke SAI cannot match. When replacing an ISO 15552 cylinder, match the 80mm bore, 40mm nominal stroke, 10mm adjustment range, G3/8 PT port, and the -S magnet requirement. For this short 40mm stroke, side-load stress is minimal, but always guide long unsupported rods externally.
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 SAIJ80AX40-10S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder produces 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the nominal 40mm stroke by up to 10mm, creating a 30-40mm usable travel window. The adjuster functions as a mechanical stop and does not hold the load without continuous air pressure.
