Airtac SE50 Standard Cylinder SE50AX375
The AirTAC Airtac SE50 Standard Cylinder SE50AX375 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 375mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE50 Standard Cylinder SE50AX375
The AirTAC SE50AX375 is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a push force of 982 N and a pull force of 825 N at 0.5 MPa. It features a SUS420J2 stainless steel rod (code A) specifically chosen for corrosive or washdown environments where a standard carbon steel rod would degrade.
The extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while exposing sensor grooves on three sides. Because this specific SKU lacks the -S magnet code, it cannot host CMSE reed or DMSE electronic position sensors without modification. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration for the 375 mm travel, protecting the mechanism from hard impacts.

Where the Airtac SE50 Standard Cylinder SE50AX375 Is Used
Bottling Line Diverter
Routes plastic bottles on a washdown conveyor using the 375 mm stroke, where the SUS420J2 stainless rod resists moisture and cleaning chemicals.
Carton Flap Folder
Folds corrugated cardboard flaps prior to sealing, utilizing the 982 N push force at 0.5 MPa to overcome spring-back resistance.
Textile Loom Tensioner
Adjusts yarn tension bars dynamically across a 375 mm span, relying on the field-adjustable air cushions to soften high-frequency end stops.
Is the Airtac SE50 Standard Cylinder SE50AX375 the Right Cylinder?
When sizing this actuator, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore increases it to 1559 N. This 50 mm bore provides a balanced middle ground for mid-range actuation. With a 375 mm stroke, the unsupported rod length increases bending moments on the rod bearing under side loads; utilizing an external guide rail prevents premature seal wear and piston drift.
This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders without altering mounting hardware. It uses a PT1/4 port and an M16x1.5 rod thread. Note that a plain SE cylinder does not hold its position or load when air is lost or the valve is centered—the piston drifts. If the application must hold a vertical load without live pressure, integrate a BSE rod lock 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 SE50AX375 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 operating speed ranges from 30-800 mm/s.
This specific SKU does not include a built-in magnet (no -S code), so it cannot support AirTAC CMSE reed or DMSE electronic sensors. If position feedback is required, select the SE50X375S variant or add external mechanical limit switches.
