Airtac SE80 Standard Cylinder SE80AX85
The AirTAC Airtac SE80 Standard Cylinder SE80AX85 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø80mm bore and 85mm stroke, PT3/8 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 SE80 Standard Cylinder SE80AX85
The AirTAC SE80AX85 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering 2513 N of push force at 0.5 MPa. Its 85 mm stroke is driven by a Ø25 mm piston rod threaded M20x1.5, operating via a PT3/8 port at speeds of 30-800 mm/s. Because it is a profile cylinder, the square extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that naturally resists corrosion and simplifies fixture integration.
This specific SKU features a SUS420J2 stainless steel rod (code A), making it highly suitable for corrosive environments or washdown duty compared to the standard medium-carbon steel rod. It carries no built-in magnet, meaning position sensing is not wired for this unit out of the box. The field-adjustable air cushion at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard mechanical stops during high-speed cycles.

Where the Airtac SE80 Standard Cylinder SE80AX85 Is Used
Palletizer Flap Folding
Uses the 2513 N push force at 0.5 MPa to cleanly fold corrugated cardboard flaps on high-speed palletizing lines, where the SUS420J2 rod withstands incidental moisture.
Washdown Fluid Diverter
Actuates a diverter valve in a food-grade washdown zone, relying on the corrosion-resistant stainless steel rod and flush extruded barrel to endure daily chemical washes.
Injection Mold Ejector
Drives an 85 mm ejection stroke on a mid-size injection molding machine, utilizing the field-adjustable air cushions to soften the rapid 30-800 mm/s end stops.
Is the Airtac SE80 Standard Cylinder SE80AX85 the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm cylinder reduces the 0.5 MPa push force to 1559 N, while stepping up to a 100 mm bore increases it to 3927 N. This SE80AX85 provides a robust 3518 N at 0.7 MPa and a maximum 513 kgf at 1.0 MPa, making it ideal for medium-heavy manipulation. As a standard ISO 15552 cylinder, it serves as a drop-in replacement for any cylinder sharing that mounting interface.
Note that a plain SE cylinder relies on live air pressure to hold its position; it will drift if air is exhausted or a valve centers. If your application requires true load holding without pressure, consider the BSE rod lock variant. For any stroke of 85 mm, side-load stress on the rod bearing is minimal, though long unsupported strokes always benefit from an external guide.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE80 Standard Cylinder SE80AX85 FAQ
The SE80AX85 generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum 513 kgf at 1.0 MPa. It features an 80 mm bore, a Ø25 mm SUS420J2 stainless steel rod with an M20x1.5 thread, and a PT3/8 air port.
No. The adjustable air cushion at both ends only decelerates the piston near stroke end; it is not a mechanical lock. A standard SE cylinder will drift if air pressure is lost or the valve is centered. For fail-safe load holding, you need the BSE variant with an external rod lock.
