Airtac SE80 Standard Cylinder SE80AX850
The AirTAC Airtac SE80 Standard Cylinder SE80AX850 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø80mm bore and 850mm 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 SE80AX850
The AirTAC SE80AX850 is a double-acting, single-rod ISO 15552 profile cylinder engineered for rigorous linear motion. It features an 80 mm bore and an 850 mm stroke, yielding a substantial 2513 N push force at 0.5 MPa and a maximum of 513 kgf at 1.0 MPa. This specific SKU incorporates a SUS420J2 stainless steel rod (code A) to resist corrosion in washdown or humid settings, and because it lacks the -S magnet code, it arrives without built-in position sensing.
Built on a square extruded aluminum barrel without external tie rods, the body is inherently compact and immune to protruding-rod snag points. The integrated pneumatic cushioning at both ends is field-adjustable via a setscrew, letting technicians dial in the exact end-of-stroke deceleration needed to absorb heavy kinetic energy without hard metal impacts.

Where the Airtac SE80 Standard Cylinder SE80AX850 Is Used
Palletizer Pusher
Uses the 2513 N thrust to deflect heavy pallets onto a secondary transfer line, where the SUS420J2 rod survives occasional washdowns.
Heavy Case Erector
Extends across the 850 mm stroke to unfold large corrugated blanks, relying on the adjustable cushion to brake the massive moving mass.
Automated Guided Vehicle Lift
Raises a 500 kgf payload platform using the 1.0 MPa max push, requiring an external guide to support the long, side-loaded 25 mm rod.
Is the Airtac SE80 Standard Cylinder SE80AX850 the Right Cylinder?
When sizing this actuator, compare its 2513 N push at 0.5 MPa against the neighboring bores: the smaller 63 mm bore yields 1559 N, while the larger 100 mm bore provides 3927 N. This 80 mm unit is optimal when the 63 mm bore lacks the necessary thrust for a heavy vertical lift, but the 100 mm bore would be physically oversized. Because this is a made-to-order 850 mm stroke that exceeds the 1500 mm standard maximum, it is a non-standard configuration.
For a stroke of this length, the 25 mm rod and M20x1.5 thread face significant bending moments under side loads; an external guide rail is strongly recommended to prevent rod-bearing wear. Furthermore, a plain SE cylinder cannot hold a suspended load if air pressure drops or the valve centers—the piston will drift. For fail-safe load holding, specify a BSE rod lock or an external pilot-operated check valve. To replace an existing actuator, match the 80 mm bore, 850 mm stroke, PT3/8 port, and ISO 15552 mounting interface.

- ✓ 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 SE80AX850 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N. The absolute maximum push force is 513 kgf when operating at the 1.0 MPa pressure limit.
No. The adjustable air cushion at both ends only decelerates the piston near the stroke ends; it is not a mechanical lock. If air is exhausted or the valve is centered, the piston will drift under load. For fail-safe holding, use a BSE series rod lock or an external pilot-operated check valve.
