About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX55-10S
The AirTAC SAIJ80X55-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel within a 45 to 55 mm window. Operating at 0.7 MPa, it delivers a robust push force of 3518 N and a pull force of 2268 N. The integrated magnet enables position sensing with CMSE reed or DMSE electronic switches.
This specific SKU features a 25 mm SUS420J2 stainless steel rod and a PT tapered G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a speed range of 30-800 mm/s and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) for versatile machine integration.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX55-10S Is Used
Machine Changeovers
Quickly reposition the retract stop within the 45-55 mm window to handle different product sizes on the same line without swapping cylinders.
Commissioning Tuning
Fine-tune the exact end position during setup to compensate for mechanical tolerances, ensuring precise alignment before locking down the system.
Assembly Pressing
Leverage the 3518 N push force at 0.7 MPa for pressing and seating operations, using the adjustable stop to control the exact depth of travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX55-10S the Right Cylinder?
Choose this 80 mm bore when your application requires significantly more thrust than the 50 mm bore (1374 N push at 0.5 MPa) but without stepping up to the massive 100 mm class (3927 N at 0.5 MPa). The 10 mm rear adjuster is ideal for dialing in exact end-of-stroke positions during commissioning or product changeovers without adding external stops.
Remember that the rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series. This configuration uses a PT port thread and a SUS420J2 rod. Because the stroke is under 300 mm, side-load concerns are minimal, but always ensure proper guiding for heavy loads.
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 SAIJ80AX55-10S FAQ
At 0.7 MPa, this 80 mm bore cylinder provides a push force of 3518 N and a pull force of 2268 N. At 0.5 MPa, the push force is 2513 N.
The rear adjuster screw lets you shorten the nominal 55 mm stroke by up to 10 mm, giving an effective travel window of 45 to 55 mm. It functions as a mechanical stop and does not lock the load without air pressure.
