About the Airtac SE50 Standard Cylinder SE50BX25SH
The AirTAC SE50BX25SH is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding environments. It delivers 982 N of push force at 0.5 MPa and features a 25 mm stroke. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that resists corrosion and mounts flush against machine frames.
Built specifically for harsh duty, this configuration pairs a SUS304 stainless steel rod for washdown resilience with a high-temperature Viton (FKM) seal, extending the operating range up to 150 C. An integrated magnet enables position detection with CMSE reed or DMSE electronic sensors, while field-adjustable air cushions at both ends allow you to fine-tune end-of-stroke deceleration.

Where the Airtac SE50 Standard Cylinder SE50BX25SH Is Used
Thermoform Packaging Press
Drives the short 25 mm stroke sealing head in high-temperature thermoforming lines, utilizing the FKM seals and 982 N push force to secure heavy film webs.
Chemical Dispensing Valve
Actuates process valves in washdown chemical environments where the SUS304 stainless rod prevents corrosion and the integrated magnet confirms valve seating.
Hot-Stamping Fixture
Positions product blanks inside 150 C hot-stamp machinery, relying on the compact tie-rod-free profile and adjustable cushions to soften hard end stops in tight spaces.
Is the Airtac SE50 Standard Cylinder SE50BX25SH the Right Cylinder?
If sizing this 50 mm bore for a specific task, note the 40 mm neighbor provides 628 N push at 0.5 MPa, while stepping up to the 63 mm bore yields 1559 N. Because this is a standard double-acting cylinder, it cannot hold a load or maintain position if air pressure drops or the valve is centered; the piston will drift. For critical load-holding, consider the BSE rod-lock variant. As a true ISO 15552 cylinder, it serves as a direct dimensional replacement sharing standard mounting interface dimensions with other ISO 15552 profile cylinders.
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 SE50BX25SH FAQ
At 0.5 MPa, the 50 mm bore provides 982 N push and 825 N pull force, increasing to 1374 N push at 0.7 MPa, with a maximum push of 200 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s, features a PT1/4 port, and uses an M16x1.5 rod thread.
Yes. The SE50BX25SH is configured with a SUS304 stainless steel rod for superior corrosion resistance and a Viton (FKM) seal that safely operates up to 150 C. It also includes a built-in magnet for CMSE and DMSE position sensors.
