About the Airtac SE80 Standard Cylinder SE80AX275S
The AirTAC SE80AX275S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic actuation. It delivers a robust 2513 N push force at 0.5 MPa and utilizes a 25 mm SUS420J2 stainless steel rod (code A) to resist corrosion in washdown or high-moisture environments. Its square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while preventing localized corrosion traps.
This 80 mm bore unit features a built-in magnet (code S) designed to interface seamlessly with AirTAC CMSE reed and DMSE electronic position sensors, which seat neatly into the sensor grooves machined on three sides of the body. Field-adjustable air cushioning at both stroke ends allows technicians to tune end-of-travel deceleration via a set screw, softening hard mechanical impacts when cycling heavy loads at speeds up to 800 mm/s.

Where the Airtac SE80 Standard Cylinder SE80AX275S Is Used
CNC Pallet Changer
Drives the heavy lateral shifting mechanism of an automated pallet pool, utilizing the 2513 N push force to shuttle loaded workholding fixtures into the machining center.
Corrugated Box Flap Folder
Folds heavy cardboard flaps on high-speed packaging lines, relying on the SUS420J2 stainless rod to withstand adhesive splatter and humid production environments.
Pallet Transfer Stopper
Acts as a robust lane stopper in 275 mm rejection strokes, using the built-in magnet and DMSE sensors to confirm load positioning before downstream robotic handoff.
Is the Airtac SE80 Standard Cylinder SE80AX275S the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate your payload against its 2513 N push at 0.5 MPa. If your application requires less force, stepping down to the 63 mm bore yields 1559 N push, conserving compressed air and physical space. Conversely, moving up to the 100 mm bore provides 3927 N push for heavier masses. Because this is a single-rod double-acting cylinder, it cannot hold a load pneumatically if air pressure is lost or the valve centers; the piston will drift. For position-holding safety, consider the AirTAC BSE rod lock variant or an external pilot-operated check valve.
At a 275 mm stroke, the 25 mm rod and thread interface carry substantial side-load capacity, but an unsupported piston rod bearing will experience bending stress under high lateral loads. To prevent premature seal wear and rod scoring over this travel distance, incorporate an external guide rail to support the payload. This model is dimensionally interchangeable per ISO 15552, allowing a direct drop-in replacement for other ISO 15552 cylinders using identical mounting hardware and the standardized PT3/8 port.
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 SE80AX275S FAQ
This 80 mm bore cylinder generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. It operates at speeds ranging from 30 to 800 mm/s.
No. The adjustable air cushion at both ends only decelerates the piston near the stroke limits; it is not a mechanical brake. If air is lost, the piston will drift. You must use an AirTAC BSE rod lock cylinder or an external pilot-operated check valve to hold vertical loads safely.
