About the Airtac SE50 Standard Cylinder SE50AX350
The AirTAC SE50AX350 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 350 mm stroke. It features a 50 mm bore that generates 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (material code A), making it highly suitable for corrosive environments or washdown duty. It lacks a built-in position sensor magnet, but retains the standard field-adjustable air cushioning at both ends to decelerate the piston near stroke end.

Where the Airtac SE50 Standard Cylinder SE50AX350 Is Used
CNC Pallet Changer Gate
Drives a 350 mm stroke to open and close the physical safety gate on a CNC machining center pallet pool, relying on the 982 N push force to overcome heavy guide friction.
Pharmaceutical Washdown Diverter
Actuates a routing flap inside a cleanroom tablet conveyor, where the SUS420J2 stainless rod withstands frequent chemical washdowns without pitting.
Corrugated Box Flap Folder
Extends 350 mm to fold the major lower flaps of large corrugated cartons on a packaging line, using adjustable end cushions to soften the impact at high cycling speeds.
Is the Airtac SE50 Standard Cylinder SE50AX350 the Right Cylinder?
This 50 mm bore provides 982 N push at 0.5 MPa. If your application requires less force, the 40 mm bore neighbor offers 628 N, while stepping up to the 63 mm bore provides 1559 N. As a standard double-acting cylinder, it cannot hold a load if air pressure is lost or the valve is centered; applications requiring true mid-stroke holding or fail-safe braking should pivot to the BSE rod-lock variant.
At 350 mm of stroke, the unsupported rod length increases bending moments on the rod bearing under side loads. To prevent premature seal wear and scoring, implement an external guide rail to carry the load mass. For retrofits, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders, using the PT1/4 port and standard mounting accessories.
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 SE50AX350 FAQ
The 50 mm bore generates 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. The operating speed ranges from 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 mounting dimensions. However, this specific SKU lacks the built-in magnet (-S), so it cannot support AirTAC CMSE or DMSE position sensors without changing the cylinder.
