About the Airtac SE50 Standard Cylinder SE50BX125
The AirTAC SE50BX125 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and 125 mm stroke. It generates 982 N of push force at 0.5 MPa and features a SUS304 stainless steel rod, making it highly suitable for corrosive or washdown environments where standard carbon steel rods would degrade.
Built with an extruded aluminum barrel that eliminates external tie rods, this unit boasts a compact, flush-mounting profile that resists corrosion and simplifies fixture design. The field-adjustable pneumatic cushioning at both ends allows you to precisely tune end-of-stroke deceleration, softening hard impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50BX125 Is Used
Flow Wrapper End-Sealing
Drives the end-sealing jaw mechanism on continuous motion flow wrappers, utilizing the 982 N push force to cleanly crimp and cut packaging film at high cycling rates.
Benchtop Centrifuge Lid
Actuates the safety lid on laboratory benchtop centrifuges, where the SUS304 stainless steel rod prevents corrosion from accidental chemical spills during testing.
CNC Pallet Changer Gate
Indexes the safety gate on an automated CNC pallet changer, moving 125 mm to allow raw material entry and finished part exit without interrupting the machining cycle.
Is the Airtac SE50 Standard Cylinder SE50BX125 the Right Cylinder?
If your application requires less force, the 40 mm bore neighbor provides 628 N of push at 0.5 MPa, whereas stepping up to the 63 mm bore yields 1559 N for heavier loads. This SE50BX125 is dimensionally interchangeable per ISO 15552, meaning it serves as a direct replacement for other standard profile cylinders without altering your mounting footprint.
Because this specific SKU lacks the -S magnet option, it cannot host CMSE or DMSE position sensors out of the box; add a sensor-equipped variant if your control system requires electronic position feedback. Furthermore, this cylinder relies on live air pressure to maintain its position and will drift if air is lost or the valve is centered; for fail-safe load holding, consider the 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 SE50BX125 FAQ
The SE50BX125 delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum push of 200 kgf at 1.0 MPa. It features a PT1/4 port and an M16x1.5 rod thread.
No, this specific SKU lacks the built-in magnet (-S option) required for AirTAC CMSE (reed) and DMSE (electronic) sensors. You must select an -S variant to enable position detection.
