About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX65-10
The AirTAC SAIJ80X65-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 55 to 65 mm usable travel window. It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it a robust choice for heavy payloads. This configuration uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads.
The rear adjustment screw lets you dial in the exact end position during commissioning without adding external stops. The barrel incorporates sensor grooves on both sides for CMSE reed and DMSE electronic switches, though this SKU is built without a magnet. The mounting set is reduced to Basic, FA, LB, TC, FTC, TCM1 and TCM2, omitting FB and rear pivot options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX65-10 Is Used
Short-Stroke Tuning
Dial in the exact 55 to 65 mm end position during machine setup to perfect clamping or ejection without swapping cylinders.
Product Changeover
Quickly adapt the travel limit for new product sizes on a packaging line using the rear stopper screw.
Heavy Positioning
Leverage the 2513 N push force to move heavy jigs into place, then fine-tune the final resting spot.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX65-10 the Right Cylinder?
Select this 80 mm bore when a 50 mm bore (offering 825 N pull at 0.5 MPa) lacks the necessary force, but you want to avoid stepping up to a 100 mm bore. The 10 mm adjustment range is ideal for fine-tuning short 65 mm strokes on product changeovers. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ does not hold position without live air. For load-holding, consider SAIL or BSAI types. To match this ISO 15552 replacement, specify: 80 mm bore, 65 mm stroke, 10 mm adjust, PT port, SUS420J2 rod, no magnet.
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 SAIJ80AX65-10 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the 65 mm nominal stroke by up to 10 mm, creating a usable travel window of 55 to 65 mm. It is a travel stop, not a lock, and the cylinder still requires live air to hold its position.
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. It operates at speeds between 30 and 800 mm/s.
