About the Airtac SE50 Standard Cylinder SE50BX250S
The AirTAC SE50BX250S is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering a 982 N push at 0.5 MPa. It uses a SUS304 stainless steel rod, making it highly suitable for corrosive environments or washdown duty where standard carbon steel rods would fail. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames.
Equipped with a built-in magnet (S code), this unit supports 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 the deceleration of the 250 mm stroke via a set screw, softening hard impacts at high cycling speeds without relying on fixed rubber bumpers.

Where the Airtac SE50 Standard Cylinder SE50BX250S Is Used
Bottling Line Diverter
Uses the 250 mm stroke and 982 N push to route plastic bottles between filling lanes, relying on the SUS304 rod to withstand caustic washdown cycles.
Pouch Sealing Press
Applies consistent downward clamping force on flexible packaging materials, with the DMSE electronic sensor verifying the fully extended position before heat sealing.
Lab Sample Ejector
Pushes processed test tube racks out of a chemical analysis unit, where the stainless steel rod prevents corrosion from reagent exposure.
Is the Airtac SE50 Standard Cylinder SE50BX250S the Right Cylinder?
This 50 mm bore provides 982 N push at 0.5 MPa. If your application requires less force, the 40 mm neighbour yields 628 N push, whereas stepping up to the 63 mm bore provides 1559 N push. Because the stroke is 250 mm, the 20 mm rod and its M16x1.5 thread will experience side-load leverage under offset loads; an external guide mechanism is recommended to prevent rod-bearing bending and premature seal wear. As a standard ISO 15552 cylinder, it serves as a direct replacement for any matching profile cylinder, utilizing the PT1/4 port and standard mounting accessories.
Note that the adjustable air cushion only decelerates the piston near the stroke end and does not act as a locking device. If the machinery loses air pressure, the cylinder will drift and cannot hold a load; for critical fail-safe holding, consider the BSE rod-lock variant or an external 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 SE50BX250S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50BX250S is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other 50 mm bore, 250 mm stroke profile cylinders, maintaining the same mounting interface and PT1/4 port size.
