About the Airtac SE50 Standard Cylinder SE50AX350S
The AirTAC SE50AX350S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and 350 mm stroke. It yields 982 N of push force and 825 N of pull force at 0.5 MPa, peaking at a 200 kgf maximum output at 1.0 MPa. The extruded aluminum barrel lacks external tie rods, yielding a compact, corrosion-resistant footprint that mounts flush against machine frames.
This specific configuration incorporates a SUS420J2 stainless steel rod (A option) for corrosive or washdown environments, alongside a built-in magnet (S option) for non-contact position sensing. The barrel features sensor grooves on three sides, allowing you to easily drop in AirTAC CMSE reed or DMSE electronic switches wherever the mounting bracket fits best.

Where the Airtac SE50 Standard Cylinder SE50AX350S Is Used
Stainless Steel Pallet Diversion
Leveraging the SUS420J2 rod and 982 N push force, this cylinder actuates diverters on washdown packaging lines, reliably pushing filled containers onto secondary chutes without succumbing to moisture corrosion.
350 mm Product Reject Stroke
The 350 mm stroke provides the extended reach needed to reject oversized or faulty parts off a moving conveyor belt, while the adjustable end cushions soften the impact at high cycling speeds.
Chemical Dosing Head Actuation
The corrosion-resistant stainless rod is ideal for driving dosing pump heads in chemical processing plants, where the DMSE electronic sensors confirm full stroke completion in hazardous environments.
Is the Airtac SE50 Standard Cylinder SE50AX350S the Right Cylinder?
If your application requires less force, the 40 mm neighbor provides 628 N of push at 0.5 MPa, while stepping up to the 63 mm bore yields 1559 N for heavier payloads. As a standard double-acting cylinder, the SE50AX350S will drift if air pressure is lost or the valve is centered; if you need static position holding, consider the BSE rod lock series or an external pilot-operated check valve. To replace an existing unit, match the 50 mm bore, 350 mm stroke, PT1/4 port, and mounting hardware, and utilize the -S magnet for sensor feedback.
Because this unit features a 350 mm stroke, the unsupported rod length increases bending moments on the rod bearing under heavy lateral loads. For long extensions, implement an external guide rail to prevent premature seal wear and stick-slip cycling.
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 SE50AX350S FAQ
At 0.5 MPa, the SE50AX350S generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N, with an absolute maximum push of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50AX350S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 50 mm bore, 350 mm stroke, PT1/4 port, and mounting accessories. The built-in magnet also allows you to use AirTAC CMSE or DMSE sensors for position detection.
