About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-20S
The AirTAC SAIJ80X230-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 230 mm stroke, the external stopper lets you dial back the effective travel by up to 20 mm, creating a 210-230 mm usable positioning window. This on-the-fly tuning is ideal for product changeovers without swapping the cylinder. It delivers a robust 3518 N push force at 0.7 MPa and includes a magnet for position sensing.
This SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The 25 mm rod and M20x1.5 thread handle high side loads, while the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits FB and CA brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-20S Is Used
Machine Setup & Changeover
Fine-tune the 210-230 mm travel window during product changeovers to establish new end positions without physically swapping the cylinder.
Variable End-Stop Positioning
Dial in the exact retract distance for multi-format production lines, using the rear stopper to adapt to different part lengths on the fly.
Heavy Fixture Handling
Leverage the 3518 N push force at 0.7 MPa to move substantial jigs and fixtures while relying on the 25 mm SUS420J2 rod for structural integrity.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-20S the Right Cylinder?
Choose this 80 mm bore when 50 mm bore cylinders (providing 1374 N push at 0.5 MPa) lack the power for heavier fixtures. The adjustable 210-230 mm window is selected over a fixed SAI stroke when you need variable end-stops for machine setup or product size changes. Because the stroke is 230 mm, ensure external guiding to prevent rod sag under side loads.
The rear adjuster acts purely as a travel stop to decelerate the end position; it does not hold the load without live air. For true load-holding without continuous pressure, use an external rod lock or pilot-operated check valve, or select the SAIL or BSAI cylinder series. To replace an ISO 15552 cylinder, match the 80 mm bore, 230 mm stroke, 20 mm adjustment, PT ports, and the -S magnet.

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 SAIJ80AX230-20S FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder provides 3518 N of push force and 2268 N of pull force. It can deliver up to 4523 N push at 0.9 MPa.
The rear adjuster acts as an external stopper that trims the effective travel. For this model, the nominal 230 mm stroke can be dialed back by up to 20 mm, providing a usable 210-230 mm positioning window. The adjuster is a stop, not a lock.
