About the Airtac SE50 Standard Cylinder SE50AX400S
The AirTAC SE50AX400S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and 400 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, utilizing a SUS420J2 stainless steel rod (code A) specifically chosen for corrosive or washdown environments. The extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames.
Equipped with a built-in position magnet (code S), this unit seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard mechanical impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX400S Is Used
Bottling Line Diverter
Utilizes the 400 mm stroke and SUS420J2 rod to push PET containers between parallel conveyor lanes during high-speed beverage packaging, tolerating frequent washdowns.
Vertical Pouch Sealing
Leverages the 982 N push force at 0.5 MPa to securely clamp and seal flexible film pouches, while the DMSE electronic sensor confirms the exact clamping position.
Lab Sample Ejection
Employs the corrosion-resistant stainless rod to eject processed biological samples from testing carousels without risking contamination from exposed cylinder internals.
Is the Airtac SE50 Standard Cylinder SE50AX400S the Right Cylinder?
When sizing this 50 mm bore actuator, evaluate your thrust envelope in both directions: stepping down to a 40 mm bore drops the 0.5 MPa push to 628 N, while stepping up to a 63 mm bore increases it to 1559 N. Because this model features a 400 mm stroke, the extended unsupported piston rod is susceptible to bending under lateral loads; always pair it with an external guide rail to prevent rod-bearing damage. As a standard ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for competing ISO 15552 cylinders, utilizing the existing PT1/4 port and standardized mounting accessories. Note that the adjustable air cushion only decelerates the piston near stroke end and does not function as a lock; if the application must hold a vertical load without live air pressure, integrate an external rod lock or pilot-operated check valve.
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 SE50AX400S FAQ
The 50 mm bore generates a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, the push force reaches 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50AX400S shares the exact ISO 15552 / VDMA 24562 mounting interface and PT1/4 port dimensions, allowing it to serve as a drop-in replacement for other standard ISO 15552 profile cylinders without modifying the machine footprint.
