About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX800-10S
The AirTAC SAIJ80X800-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 800 mm travel by up to 10 mm. This creates a precise 790-800 mm usable window for fine-tuning the retract end position without adding external stops. It delivers 2513 N of pull force at 0.5 MPa and reaches up to 4523 N at 0.9 MPa.
This variant features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet for position sensing with CMSE reed or DMSE electronic sensors. The extruded aluminum barrel carries sensor grooves on both sides. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX800-10S Is Used
Machine Changeover
Quickly fine-tune the retract end-stop by up to 10 mm when switching product sizes on a packaging line, eliminating the need for custom spacer shims.
End-Position Calibration
Dial in the exact 790-800 mm travel window during commissioning to perfect a critical assembly press without physically altering the cylinder setup.
Automated Material Handling
Drive long-travel indexing gates on a conveyor, using the rear stopper to absorb kinetic energy and set the precise resting position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX800-10S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires exact end-position tuning at commissioning or during product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. If you need less force, stepping down to a 63 mm bore yields 1402 N of pull at 0.5 MPa; if your application demands more force, stepping up to a 100 mm bore provides 3681 N of pull at 0.5 MPa.
To match this ISO 15552 cylinder for a replacement, verify the 80 mm bore, 800 mm stroke, 10 mm adjustment range, PT tapered port thread, and the -S magnet option. At 800 mm of travel, the 25 mm rod diameter and M20x1.5 thread carry good side-load capacity, but long unsupported strokes still require an external guide to prevent rod deflection. For load-holding without live pressure, use a SAIL or BSAI cylinder instead of relying on the adjuster. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80AX800-10S FAQ
At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force increases to 4523 N, and the maximum operating pressure is 1.0 MPa.
A rear external stopper screw lets you shorten the effective travel from the nominal 800 mm down to 790 mm. This provides a 790-800 mm adjustable window for fine-tuning the retract position, but it functions as a stop, not a lock, and cannot hold the load without live air pressure.
