About the Airtac SE50 Standard Cylinder SE50AX550S
The AirTAC SE50AX550S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 550 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, utilizing a 50 mm bore and a PT1/4 port. Equipped with a SUS420J2 stainless steel rod (code A), it is purpose-built for corrosive environments and washdown duty where standard carbon steel rods would pit or degrade.
This extruded aluminum barrel design eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting contamination. The integrated magnet (-S) enables precise end-of-stroke detection using AirTAC CMSE reed or DMSE electronic sensors. Furthermore, the field-adjustable air cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard mechanical stops during high-velocity cycling.

Where the Airtac SE50 Standard Cylinder SE50AX550S Is Used
Bottling Line Diverter
Routes polyethylene terephthalate containers on a washdown packaging line, leveraging the 982 N push force and SUS420J2 stainless rod to withstand harsh chemical cleaning regimes.
Lab Sample Dispenser
Actuates a 550 mm travel carriage for precise fluid handling in diagnostic equipment, relying on the -S magnet and DMSE electronic sensors for exact positioning feedback.
Textile Loom Tensioner
Maintains dynamic tension on synthetic fiber strands during high-speed weaving, using the field-adjustable air cushions to soften end-of-stroke impacts and prevent yarn snapping.
Is the Airtac SE50 Standard Cylinder SE50AX550S the Right Cylinder?
Selecting the SE50AX550S is optimal when your application requires approximately 982 N of push force at 0.5 MPa alongside a lengthy 550 mm travel. If you need to scale down, the 40 mm bore variant provides 628 N of push at 0.5 MPa. Conversely, stepping up to the 63 mm bore yields 1559 N of push at 0.5 MPa for heavier payloads. Because this cylinder features a 550 mm stroke, the extended unsupported piston rod is susceptible to bending under lateral loads; always pair it with an external linear guide to prevent rod-bearing damage.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, offering a seamless direct replacement for existing setups using the same 50 mm bore, 550 mm stroke, PT1/4 port, and standard mounting accessories. Note that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking device. If air pressure is lost, the cylinder will drift, requiring a BSE rod lock or external pilot-operated check valve to hold a vertical load safely.
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.
