About the Airtac SE50 Standard Cylinder SE50AX450S
The AirTAC SE50AX450S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and 450 mm stroke. It delivers 982 N of push force at 0.5 MPa, utilizing a SUS420J2 stainless steel rod (code A) specifically designed to resist corrosion in washdown or humid manufacturing environments.
This extruded aluminum body omits external tie rods for a flush, compact footprint while integrating a built-in magnet (code S) for non-contact position sensing. You can fine-tune the field-adjustable pneumatic cushioning at both ends via a setscrew to soften end-of-stroke impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX450S Is Used
Bottling Line Diverter
Uses the 450 mm stroke and 982 N push to deflect PET bottles between filling lanes, with the SUS420J2 rod enduring frequent moisture exposure.
Corrugated Box Flap Folder
Extends fully to fold heavy cardboard flaps on automated packaging machines, relying on adjustable cushioning to soften the 800 mm/s end-stop impact.
Lab Sample Indexer
Shifts sample trays precisely along a 450 mm path, using the built-in magnet with DMSE solid-state sensors to confirm exact rack positioning.
Is the Airtac SE50 Standard Cylinder SE50AX450S the Right Cylinder?
When sizing this 50 mm bore, step down to a 40 mm cylinder for lighter loads yielding 628 N push at 0.5 MPa, or step up to a 63 mm unit if your application requires 1559 N. Because this model features a 450 mm stroke, the extended rod is subject to bending under lateral loads; always support the load with an external guide to prevent rod-bearing wear. As a standard ISO 15552 cylinder, it provides drop-in dimensional interchangeability for retrofits using existing mounting hardware, a PT1/4 port, and CMSE or DMSE electronic sensors.
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 SE50AX450S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force due to the single-rod design. At 0.7 MPa, the push force increases to 1374 N, and it achieves a maximum push capacity of 200 kgf at 1.0 MPa.
No, the standard SE cylinder does not hold position upon air loss and the piston will drift. The adjustable air cushion only decelerates the piston near stroke end and does not act as a brake. For secure load holding, you must use a BSE rod lock variant or an external pilot-operated check valve.
