About the Airtac SE50 Standard Cylinder SE50AX210
The AirTAC SE50AX210 is a double-acting single-rod ISO 15552 profile cylinder featuring a 50 mm bore and a 210 mm non-standard stroke. It delivers a robust 982 N push force at 0.5 MPa, making it well-suited for mid-range automation tasks. The rod is constructed from SUS420J2 stainless steel (option A), providing superior corrosion resistance for washdown or mildly acidic environments.
This model utilizes a square extruded aluminum barrel without external tie rods, yielding a compact footprint that mounts flush against machine frames. While it lacks a built-in position-sensing magnet, it retains field-adjustable air cushioning at both ends. This allows technicians to tune the end-of-stroke deceleration via a set screw, effectively softening hard impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX210 Is Used
Pouch Forming Sealer
Drives the cross-sealing jaw on a vertical form-fill-seal machine, using its 982 N thrust and 210 mm travel to cleanly crimp packaging film in humid environments.
Bottle Divert Gate
Actuates a routing flap on a stainless steel conveyor in a beverage plant, where the SUS420J2 rod resists caustic washdown chemicals.
Textile Loom Beam
Shifts a tensioning beam on a weaving loom, relying on the adjustable pneumatic cushion to silently absorb kinetic energy at stroke end.
Is the Airtac SE50 Standard Cylinder SE50AX210 the Right Cylinder?
Selecting this 50 mm bore makes sense when your application requires around 982 N of push force at 0.5 MPa. If your load is lighter, stepping down to the 40 mm bore yields 628 N of push, whereas heavier loads would justify stepping up to the 63 mm bore for 1559 N. The 210 mm stroke is a made-to-order length outside the standard list, so expect a brief lead time.
Because this stroke exceeds 300 mm? No, but at 210 mm with a 20 mm rod and M16x1.5 thread, you still get excellent side-load capacity, though any long unsupported load should use an external guide. As a double-acting cylinder, it will drift if air pressure is lost or the valve is centered; it cannot hold a load without live pressure, so consider a BSE rod lock for strict holding requirements. It is dimensionally interchangeable per ISO 15552, accepting standard PT1/4 ports and shared mounting accessories like FA or LB brackets.
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 SE50AX210 FAQ
At 0.5 MPa, this 50 mm 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 push capacity of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, its mounting interface and PT1/4 port dimensions are fully interchangeable with other ISO 15552 profile cylinders. However, it does not hold position unpowered; the adjustable air cushion only decelerates the piston near the end of stroke and is not a locking mechanism.
