About the Airtac SE50 Standard Cylinder SE50X720S
The AirTAC SE50X720S is a double-acting single-rod ISO 15552 profile cylinder, delivering 982 N of push force at 0.5 MPa across its 720 mm stroke. Its square extruded aluminum barrel eliminates external tie rods, yielding a flush, corrosion-resistant body that mounts cleanly into tight machine frames.
Because this unit includes the -S magnet code, it is fully primed for AirTAC CMSE reed and DMSE electronic position sensing. The field-adjustable pneumatic cushioning at both stroke ends lets technicians dial in end-stop deceleration to absorb kinetic energy smoothly, protecting the mechanics during high-velocity traversals.

Where the Airtac SE50 Standard Cylinder SE50X720S Is Used
Pallet Diverters
Uses the 982 N push force and 720 mm stroke to actuate diverter arms on packaging conveyor lines, relying on the -S magnet for DMSE timing confirmation.
CNC Lathe Doors
Slides heavy machine tool safety doors across the 720 mm span, benefiting from the tie-rod-free extruded profile that prevents debris buildup.
Lab Sample Handlers
Drives linear motion racks in automated blood-testing analyzers, where the field-adjustable cushions soften end-stop impact to protect vials.
Is the Airtac SE50 Standard Cylinder SE50X720S the Right Cylinder?
At 982 N push (0.5 MPa), this 50 mm bore is a solid mid-range choice; if your payload drops, the 40 mm bore offers 628 N, while stepping up to the 63 mm bore yields 1559 N. The 720 mm stroke is a standard length for this bore, but at this reach the Ø20 mm rod and bearing face bending stresses under side loads, so an external guide rail is strongly recommended to prevent premature wear. Remember that the adjustable air cushions only decelerate the piston near stroke ends; they do not lock or hold a load if air pressure is lost. For drop-in retrofits, this ISO 15552 profile matches standard mounting footprints and uses a PT1/4 port.
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 SE50X720S FAQ
This 50 mm bore cylinder provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa. Its operating speed range is 30-800 mm/s.
Yes. The SE50X720S is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards, meaning it shares the exact same mounting and port footprint (PT1/4) as other standard profile cylinders, though it is not identical to any specific brand's part.
