About the Airtac SE50 Standard Cylinder SE50AX500
The AirTAC SE50AX500 is a double-acting single-rod ISO 15552 profile cylinder engineered for a 500 mm stroke. It features a SUS420J2 stainless steel piston rod (option A), making it highly suitable for corrosive or washdown environments where standard carbon steel rods would degrade.
Delivering 982 N of push force and 825 N of pull force at 0.5 MPa, this unit relies on an extruded aluminum barrel without external tie rods. This clean profile design prevents contaminant buildup and allows flush mounting. Please note this specific SKU lacks a built-in magnet, meaning it cannot directly host CMSE or DMSE position sensors without modification.

Where the Airtac SE50 Standard Cylinder SE50AX500 Is Used
Stainless Food Packaging
Drives a 500 mm transfer arm in washdown packaging lines, utilizing the SUS420J2 rod for corrosion resistance while providing 982 N push force at 0.5 MPa.
Bottle Conveyor Divert
Actuates a 500 mm routing gate on a beverage conveyor, where the tie-rod-free extruded barrel prevents grease and debris accumulation during high-speed sortation.
Lab Sample Indexing
Positions sample trays in clinical analyzers over a 500 mm span, relying on field-adjustable air cushions at both ends to soften end-of-stroke impacts and protect delicate vials.
Is the Airtac SE50 Standard Cylinder SE50AX500 the Right Cylinder?
When sizing this 50 mm bore, consider stepping down to a 40 mm bore (628 N push at 0.5 MPa) for lighter duties, or upgrading to a 63 mm bore (1559 N push at 0.5 MPa) if your load requires significantly more extension force. Because this is a standard double-acting cylinder, it will drift if air pressure is lost or a valve centers; use a BSE rod lock variant if the application demands mechanical position holding.
At 500 mm of stroke, the unsupported rod length increases bending moments on the rod bearing under side loads. To prevent premature seal wear, always guide the load externally. Furthermore, its standardized ISO 15552 mounting dimensions guarantee a direct drop-in replacement for other ISO 15552 profile cylinders, simplifying retrofits.
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 SE50AX500 FAQ
The SE50AX500 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. It uses a PT1/4 port and operates at speeds of 30-800 mm/s.
No, the SE50AX500 is a standard double-acting cylinder and will drift if air is lost. Its field-adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the rod. For true position holding, consider the AirTAC BSE rod lock series.
