About the Airtac SE50 Standard Cylinder SE50X700S
The AirTAC SE50X700S is a double-acting, single-rod ISO 15552 profile cylinder engineered for long-stroke automation. It delivers a robust 982 N push force at 0.5 MPa alongside an 825 N pull force, utilizing a 50 mm bore and a 700 mm stroke. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific configuration includes a built-in magnet (-S) for position sensing, designed to interface directly with AirTAC CMSE reed and DMSE electronic switches. To protect the end caps during high-velocity cycling across its extended 700 mm travel, the cylinder relies on field-adjustable pneumatic cushioning at both ends. You can tune these cushion needles on-site to soften hard end stops precisely for your moving load.

Where the Airtac SE50 Standard Cylinder SE50X700S Is Used
Pallet Diverters
Pushes heavy pallets across transfer lines using its 982 N thrust and 700 mm reach, with the -S magnet tracking divert positions.
Case Erectors
Folds and seals large cardboard cartons, relying on the adjustable cushions to gently stop the 700 mm stroke at high speeds.
Vertical Lift Gates
Raises material handling access doors where the 825 N pull force retracts the barrier fully into the ceiling frame.
Is the Airtac SE50 Standard Cylinder SE50X700S the Right Cylinder?
Selecting this 50 mm bore makes sense when your application requires the 982 N push at 0.5 MPa that it provides. If you need less force and want a smaller footprint, stepping down to the 40 mm bore yields 628 N of push. Conversely, if your load demands more thrust, stepping up to the 63 mm bore provides 1559 N. Because this model features a 700 mm stroke, the 20 mm rod and internal bearing face significant bending moments under side loads; always support the load with an external guide to prevent premature seal wear. As a standard ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders, utilizing standard PT1/4 ports and your chosen mounting accessories.
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 SE50X700S FAQ
At 0.5 MPa, it provides 982 N of push and 825 N of pull force. At 0.7 MPa, the push increases to 1374 N. The maximum push force is 200 kgf when operated at the 1.0 MPa pressure limit.
No, the adjustable air cushions only decelerate the piston near the stroke ends and do not act as a brake. If your application must hold a vertical load without live pressure, you need a BSE rod lock variant or an external pilot-operated check valve.
