About the Airtac SE50 Standard Cylinder SE50AX85S
The AirTAC SE50AX85S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a push force of 982 N at 0.5 MPa. It features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance in washdown or humid environments, and includes a built-in position magnet (code S) for seamless integration with AirTAC CMSE reed or DMSE electronic sensors.
Its square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames. The field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration, protecting tooling from hard mechanical impacts at operating speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX85S Is Used
Stainless Steel Pouch Sealing
Drives a heated sealing jaw on a vertical form-fill-seal machine, using the 982 N push force and SUS420J2 rod to withstand daily chemical washdowns in food packaging lines.
Washdown Transfer Gate
Actuates a diverter gate on a stainless steel conveyor system in a bottling plant, where the 85 mm stroke rapidly redirects product flow while resisting moisture corrosion.
PCB Router Clamping
Secures printed circuit board panels during a routing operation, utilizing the built-in S magnet and DMSE electronic sensors to confirm clamp engagement before the spindle starts.
Is the Airtac SE50 Standard Cylinder SE50AX85S the Right Cylinder?
This 50 mm bore provides 982 N push at 0.5 MPa. If your application requires less force, stepping down to the 40 mm bore yields 628 N of push, while moving up to the 63 mm bore provides 1559 N. As a true ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders, matching the exact mounting interface, PT1/4 port, and 85 mm stroke. If the application must hold a vertical load without live air pressure, note that the adjustable cushion only decelerates the piston and does not act as a brake; an external rod lock or pilot-operated check valve is required for position holding.
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 SE50AX85S FAQ
