About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-40
The AirTAC SAIJ80X230-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 2513N of push force at 0.5 MPa and provides a usable travel window of 190 to 230mm, letting you dial back the nominal stroke by up to 40mm during commissioning.
This model uses a G3/8 port and a 25mm carbon steel rod with an M20x1.5 thread. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set spans Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear stopper and adjustable air cushions only decelerate the load; they do not hold it without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-40 Is Used
End-Position Tuning
Fine-tune the retract distance within the 190-230mm window during machine commissioning to hit exact positioning targets without adding external stopper blocks.
Product Changeover
Quickly adjust the stroke by up to 40mm to accommodate different product sizes on a packaging line, reducing downtime between production runs.
Variable End Stops
Use the rear adjuster screw to set precise end-of-stroke limits for assembly presses, relying on the 2513N thrust at 0.5 MPa for consistent clamping.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-40 the Right Cylinder?
Choose this 80mm bore when a 50mm bore yields too little thrust (982N at 0.5 MPa) and a 100mm bore is excessive (3927N). The 40mm adjustment window is ideal for machine setups requiring variable end-stops or product-size changeovers without swapping cylinders. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is a stop, not a lock. This unit is dimensionally interchangeable per ISO 15552 and uses PT tapered ports. With a 230mm stroke, guide external rods to prevent side-load wear on the 25mm piston rod.
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 SAIJ80X230-40 FAQ
At a 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw lets you shorten the effective travel from the 230mm nominal stroke down to 190mm. This creates a 190-230mm adjustable window, allowing precise end-position tuning at commissioning without replacing the cylinder.
