About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-10S
The AirTAC SAIJ80X90-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, providing a usable travel window of 80-90 mm. Delivering 2513 N of push force and 2268 N of pull force at 0.5 MPa, it handles robust actuation tasks. The integrated -S magnet supports position sensing via CMSE reed or DMSE solid-state switches.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load. For position holding without live air pressure, an external rod lock or a SAIL/BSAI series cylinder is required.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-10S Is Used
Machine Setup Tuning
Dial in the exact 80-90 mm retract stop during initial commissioning without machining custom external spacers.
Product Changeover
Quickly adjust the end-of-stroke position on a packaging line when switching to a slightly different carton size.
Assembly Pressing
Apply 2513 N of precise pressing force while using the rear stopper to prevent over-travel on delicate components.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-10S the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N push @ 0.5 MPa) is too weak or 100 mm (3927 N push @ 0.5 MPa) is oversized. The 10 mm adjustment window is ideal for dialing in exact end-stops during machine setup without adding external stopper blocks. The 25 mm rod and M20x1.5 thread handle high side loads well.
To match this ISO 15552 footprint, specify an 80 mm bore, 90 mm stroke, 10 mm adjustment, PT ports, SUS420J2 (A) rod material, and a magnet for sensors. Because the total stroke is under 300 mm, external guide rails are less critical, but always verify lateral load limits. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80AX90-10S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder outputs 2513 N of push force and 2268 N of pull force. The standard speed range is 30-800 mm/s.
The rear mechanical screw allows you to shorten the nominal 90 mm stroke by up to 10 mm, creating a usable travel window of 80-90 mm. This stopper only sets the end position and does not hold the load without continuous air pressure.
