About the Airtac SE50 Standard Cylinder SE50AX140S
The AirTAC SE50AX140S is a double-acting single-rod ISO 15552 profile cylinder engineered with a 50 mm bore and 140 mm stroke. It provides a robust 982 N push force at 0.5 MPa, utilizing a PT1/4 port and a 20 mm rod. Equipped with a SUS420J2 stainless steel rod, this variant is specifically designed to resist corrosion in washdown or chemically exposed environments.
The extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush while exposing sensor grooves on three sides. Because this unit includes a built-in magnet, it is fully primed for non-contact position detection using AirTAC CMSE reed or DMSE electronic solid-state switches.

Where the Airtac SE50 Standard Cylinder SE50AX140S Is Used
Bottling Line Diverters
The SUS420J2 stainless rod withstands washdowns while delivering 982 N push to route glass containers between filling lanes.
Case Erector Jaws
Provides 825 N retract force to fold corrugated cardboard flaps, utilizing the 140 mm stroke to clear the packaging tooling.
CNC Pallet Stops
Uses the built-in magnet with DMSE sensors to confirm pallet arrival, applying 1374 N at 0.7 MPa to halt heavy machining fixtures.
Is the Airtac SE50 Standard Cylinder SE50AX140S the Right Cylinder?
If 982 N of push is insufficient, stepping up to the 63 mm bore yields 1559 N at 0.5 MPa; conversely, scaling down to the 40 mm bore provides 628 N. As a standard double-acting cylinder, the SE50AX140S will drift if air pressure is lost or the valve centers, so an external rod lock or pilot-operated check valve is required for fail-safe load holding. To guarantee a seamless retrofit, match the 50 mm bore, 140 mm stroke, PT1/4 port, and the desired mounting accessory.
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 SE50AX140S FAQ
This 50 mm bore cylinder features a PT1/4 port and generates 982 N push and 825 N pull at 0.5 MPa. At 0.7 MPa, the push force is 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa.
Yes, the SE50AX140S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders using the same mounting hardware, provided you match the 50 mm bore and 140 mm stroke.
