About the Airtac SE50 Standard Cylinder SE50BX25S
The AirTAC SE50BX25S is a double-acting, single-rod ISO 15552 profile cylinder engineered for rigorous linear motion tasks. Operating at 0.5 MPa, it generates 982 N of push force and 825 N of pull force, scaling to a maximum of 200 kgf at 1.0 MPa. The extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies fixture integration.
This specific configuration features a SUS304 stainless steel rod (code B) for superior resistance in washdown or corrosive environments, paired with a built-in magnet (code S) for position detection. The magnet interfaces seamlessly with AirTAC CMSE reed and DMSE electronic sensors fitted into the three-sided sensor grooves. Field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration, softening hard impacts during high-speed 30-800 mm/s cycles.

Where the Airtac SE50 Standard Cylinder SE50BX25S Is Used
Flow Wrapper Infeed
Drives the infeed gate on a continuous flow wrapper, using the 982 N push force and 25 mm stroke to precisely time product entry without stalling the high-speed film web.
Lab Sample Diverting
Actuates a washdown diverter arm in a clinical diagnostics analyzer, relying on the SUS304 rod to resist chemical exposure and the -S magnet for exact positional feedback.
PCB Router Clamping
Secures thin printed circuit boards during a routing operation, applying 825 N of retract pull to hold the panel flat against a vacuum fixture while the spindle cuts traces.
Is the Airtac SE50 Standard Cylinder SE50BX25S the Right Cylinder?
Stepping down to the 40 mm bore reduces the 0.5 MPa push to 628 N, whereas moving up to the 63 mm bore increases it to 1559 N, allowing you to scale power precisely to your load. Because this is a double-acting cylinder, it cannot hold a load unpowered if air is lost or the valve centers; the piston will drift, so a BSE rod lock or external pilot-operated check valve is required for strict position holding. As a true ISO 15552 component, it is dimensionally interchangeable with other ISO 15552 profile cylinders, sharing standard mounting accessories, PT1/4 ports, and a 25 mm stroke. The 20 mm rod and M16x1.5 thread handle moderate side loads well, though long unsupported strokes still necessitate an external guide.
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 SE50BX25S FAQ
This 50 mm bore cylinder delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa. It features a PT1/4 port, a 20 mm rod, and an M16x1.5 rod-end thread.
