About the Airtac SE50 Standard Cylinder SE50AX1000S
The AirTAC SE50AX1000S is a double-acting single-rod ISO 15552 profile cylinder featuring a 50 mm bore and a 1000 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, making it well-suited for long-travel positioning tasks. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while leaving three sensor grooves open for flexible switch placement.
Configured with a SUS420J2 stainless steel rod (code A) and a built-in magnet (code S), this unit is purpose-built for washdown or mildly corrosive environments requiring position feedback. The integrated magnet interfaces directly with AirTAC CMSE reed and DMSE electronic sensors along the body grooves. Furthermore, the field-adjustable air cushions at both ends allow technicians to fine-tune end-of-stroke deceleration, softening hard impacts when cycling heavy loads at speed.

Where the Airtac SE50 Standard Cylinder SE50AX1000S Is Used
Bottling Line Diversion
With its 1000 mm stroke and SUS420J2 stainless rod, this cylinder is ideal for pushing beverage containers between processing lanes during washdown cycles.
Palletizer Strapping
The 982 N push force at 0.5 MPa provides ample power to tension and seal steel strapping around palletized goods in high-humidity warehouse environments.
Water Treatment Valve Actuation
Leveraging the 50 mm bore and corrosion-resistant rod, it actuates large-diameter butterfly valves across a 1-meter span in municipal water treatment plants.
Is the Airtac SE50 Standard Cylinder SE50AX1000S the Right Cylinder?
When sizing this actuator, consider stepping down to a 40 mm bore (providing 628 N push at 0.5 MPa) for lighter loads, or moving up to a 63 mm bore (delivering 1559 N push at 0.5 MPa) if your application demands greater thrust. As a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standard mounting accessories like FA front flanges or TC center trunnions. The porting is PT1/4, and the rod end utilizes an M16x1.5 thread. Because the stroke is 1000 mm, the unsupported piston rod is highly susceptible to bending under side loads; an external guide rail is strongly recommended to prevent rod-bearing damage. Note that this cylinder relies on live air pressure to maintain position and will drift if air is lost or the valve is centered—if static holding is required, explore a BSE rod lock variant.
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 SE50 Standard Cylinder SE50AX1000S FAQ
This 50 mm bore cylinder generates 982 N push and 825 N pull at 0.5 MPa. At 0.7 MPa, the push force increases to 1374 N. The maximum allowable push force is 200 kgf at 1.0 MPa.
No, the SE50AX1000S is a double-acting cylinder that relies on continuous air pressure to maintain position; the adjustable air cushion only decelerates the piston near stroke end and does not act as a brake. If static load holding is required, consider an AirTAC BSE rod lock cylinder or an external pilot-operated check valve.
