About the Airtac SE80 Standard Cylinder SE80AX550
The AirTAC SE80AX550 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty linear motion. It delivers a robust 2513 N push force at 0.5 MPa, utilizing an 80 mm bore and a 550 mm stroke. The barrel features an extruded aluminum design without external tie rods, creating a compact, flush-mounting body that naturally resists debris buildup and corrosion.
This specific SKU is configured with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance in washdown or humid environments. It operates at speeds from 30-800 mm/s and includes field-adjustable air cushioning at both ends to decelerate the piston smoothly. Note that this unit lacks a built-in magnet, so position sensing is not supported on this particular configuration.

Where the Airtac SE80 Standard Cylinder SE80AX550 Is Used
Bottling Line Diverter
Routes heavy beverage crates on a packaging line, utilizing the 2513 N push force to pivot full pallets while the SUS420J2 rod withstands routine washdowns.
CNC Lathe Door Actuator
Opens and closes heavy machine tool safety doors across a 550 mm span, relying on the adjustable end cushions to prevent hard slamming impacts.
Pneumatic Press Ejector
Ejects formed metal parts from a hydraulic press, using the 3518 N extend force at 0.7 MPa to reliably push stuck components clear of the lower die.
Is the Airtac SE80 Standard Cylinder SE80AX550 the Right Cylinder?
When sizing this 80 mm bore cylinder, consider stepping down to the 63 mm bore if your application requires less force, as it provides 1559 N push at 0.5 MPa. Conversely, if you need to move heavier loads, stepping up to the 100 mm bore yields 3927 N push at 0.5 MPa. Because this unit has a 550 mm stroke, the unsupported rod length increases the risk of rod-bearing bending under side loads; always incorporate an external guide rail to prevent premature seal wear. As a standard ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, matching the 80 mm bore, 550 mm stroke, PT3/8 port, and standard mounting accessories. Remember that the adjustable air cushion only decelerates the piston near the stroke end—it does not hold the load. If air pressure is lost, the piston will drift, requiring a BSE rod lock for secure positioning.
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 SE80AX550 FAQ
The SE80AX550 generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 3518 N, with a maximum push capacity of 513 kgf at 1.0 MPa. It operates at pressures from 0.15-1.0 MPa and speeds of 30-800 mm/s.
This specific SKU does not include a built-in magnet, so it is not compatible with CMSE or DMSE position sensors without modification. It does feature field-adjustable air cushioning at both ends, allowing you to tune the needle valve to soften the piston's impact as it reaches the stroke endpoints, though it does not lock the load in place.
