About the Airtac SE50 Standard Cylinder SE50AX500S
The AirTAC SE50AX500S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 500 mm stroke. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, peaking at a 200 kgf maximum thrust at 1.0 MPa. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while leaving three sensor grooves open for positioning switches.
This specific configuration features a SUS420J2 stainless steel rod (code A) for washdown and corrosive environments, and includes a built-in magnet (code S) for non-contact detection. Field-adjustable pneumatic cushioning at both ends allows you to tune the end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-800 mm/s cycling without relying on fixed rubber bumpers.

Where the Airtac SE50 Standard Cylinder SE50AX500S Is Used
Stainless Food Conveyor Diverter
Uses the 982 N push force and SUS420J2 rod to deflect heavy packaged goods on a washdown line, cycling at speed without tie-rod crevices trapping debris.
Corrugated Box Flap Folder
Leverages the 500 mm stroke to fold large carton flaps, relying on the built-in magnet and DMSE electronic sensors to confirm full extension.
Lab Sample Indexing Gate
Employs the corrosion-resistant A-code rod material to withstand chemical mists while indexing test tube racks with adjustable cushioning to prevent glass-shattering impacts.
Is the Airtac SE50 Standard Cylinder SE50AX500S the Right Cylinder?
When sizing this 50 mm bore, compare its 982 N push at 0.5 MPa against the neighbouring 40 mm bore (628 N push) if your load is lighter, or step up to the 63 mm bore (1559 N push) for heavier thrust. Because this is a single-rod double-acting cylinder, it will drift if air pressure is lost or the valve centers; it cannot hold a vertical load without live pressure. For secure holding, integrate an external pilot-operated check valve or select the BSE rod-lock variant.
At 500 mm of stroke, the unsupported SUS420J2 rod and front bearing face a higher risk of bending under side loads. Implement an external linear guide to prevent premature seal wear and rod deflection. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement sharing standard mounting interface dimensions, PT1/4 ports, and M16x1.5 rod threads with equivalent cylinders.
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 SE50AX500S FAQ
At 0.5 MPa, the SE50AX500S provides 982 N push and 825 N pull force, increasing to 1374 N push at 0.7 MPa, with a maximum thrust of 200 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
Yes, the SE50AX500S is dimensionally interchangeable per ISO 15552 standards. It shares the same 50 mm bore, 500 mm stroke, PT1/4 port, and M16x1.5 rod thread footprint, allowing it to drop in as a replacement for other ISO 15552 profile cylinders.
