Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-100
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 105mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-100
The AirTAC SAIJ80X105-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 2513N push force at 0.5 MPa, utilizing a 25mm carbon steel rod and G3/8 PT tapered ports. The built-in adjustment mechanism allows the 105mm nominal stroke to be dialed back by up to 100mm, creating a highly flexible 5-105mm usable travel window for dynamic machine setups.
Unlike a fixed-stroke SAI cylinder, this model enables precise end-position tuning at commissioning without swapping hardware. The rear adjuster acts purely as a mechanical stop for deceleration and does not hold the load without live air pressure. It retains standard variable air cushions at both ends and offers a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-100 Is Used
Machine Changeover
Dial the end-stop from 5mm to 105mm to accommodate different product lengths on the same conveyor line without physically swapping the actuator.
End-Position Tuning
Fine-tune the exact retraction point during commissioning to perfect a 2513N push operation, avoiding the need to add external mechanical stops.
Variable Assembly Stops
Adjust the travel window on the fly for multi-stage assembly lines where the required cylinder reach changes based on the specific workstation configuration.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-100 the Right Cylinder?
Choose this 80mm bore cylinder when your application requires substantial thrust, such as 2268N pull at 0.5 MPa, alongside extreme stroke variability. The 5-105mm adjustable window is ideal for product-size changeovers on a line, allowing operators to dial in the exact end-stop on the fly. If your force requirements are lower, stepping down to a 50mm bore yields 825N pull at 0.5 MPa, while a 100mm bore provides 3681N pull for heavier loads.
When specifying a replacement, match the 80mm bore, 105mm nominal stroke, 100mm adjustment range, G3/8 PT ports, and the carbon steel rod. Because this SKU lacks the -S magnet option, it cannot host CMSE or DMSE sensors. Remember that the rear stopper is not a locking device; for true load-holding without continuous air pressure, select an SAIL or BSAI cylinder. For any stroke over 300mm, an external guide is recommended to manage side loads, though this 105mm travel is well within standard rod limits.
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 SAIJ80X105-100 FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 100mm. This creates a usable stroke window from 5mm to 105mm, letting you set the exact end position without replacing the cylinder.
At 0.5 MPa operating pressure, it provides 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 4523N.
