About the Airtac SE50 Standard Cylinder SE50AX290S
The AirTAC SE50AX290S 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 and a maximum thrust of 200 kgf at 1.0 MPa. It features a SUS420J2 stainless steel rod (code A) specifically chosen for corrosive environments and washdown duty. The square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting moisture buildup.
This 50mm bore, 290mm stroke unit includes a built-in magnet (code S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. Field-adjustable air cushioning at both ends allows technicians to tune the end-of-stroke deceleration via a set screw, softening hard impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX290S Is Used
Pouch Forming Jaws
Drives the vertical sealing jaws on continuous-motion packaging lines, using its 982 N thrust and 290mm stroke to cleanly crimp and sever laminated films in damp environments.
Washdown Diverter Gate
Actuates a routing flap on a food-grade conveyor, leveraging the SUS420J2 stainless rod to withstand daily high-pressure washdowns without pitting.
Lab Sample Indexing
Pushes centrifuge tube racks into a scanning station, using the integrated magnet to trigger DMSE electronic sensors for precise 290mm displacement confirmation.
Is the Airtac SE50 Standard Cylinder SE50AX290S the Right Cylinder?
Selecting this 50mm bore provides 982 N push at 0.5 MPa. If your application requires less force, stepping down to the 40mm bore yields 628 N push, while moving up to the 63mm bore provides 1559 N push for heavier loads. Because this cylinder uses a PT1/4 port and a Ø20mm rod, it shares mounting accessories and flow controls with standard ISO 15552 hardware, making it a drop-in retrofit for existing setups.
With a 290mm stroke, the unsupported piston rod is subject to bending under side loads; utilize an external guide rail to prevent premature rod-bearing wear. Remember that the adjustable air cushion only decelerates the piston near stroke end and does not hold the load—if air pressure is lost, the cylinder will drift, requiring a BSE rod lock for secure positioning.
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 SE50AX290S FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum thrust of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50AX290S is dimensionally interchangeable per ISO 15552, meaning it shares the exact mounting footprint, PT1/4 port size, and M16x1.5 rod thread of other standard profile cylinders, allowing for a direct drop-in replacement.
