About the Airtac SE50 Standard Cylinder SE50X70FA
The AirTAC SE50X70FA is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It features a 50 mm bore and a 70 mm stroke, generating 982 N of push force and 825 N of pull force at 0.5 MPa. Equipped with a front flange (FA) mounting interface, it provides a robust anchor point for heavy face-mounted loads.
This unit utilizes a square extruded aluminum barrel without external tie rods, resulting in a compact footprint that resists corrosion and mounts flush against machine frames. The field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration, protecting the mechanism from harsh impacts. Note that this specific SKU lacks a built-in magnet, so it does not support CMSE or DMSE electronic position sensing without modification.

Where the Airtac SE50 Standard Cylinder SE50X70FA Is Used
Carton Erector Flaps
Drives the folding arms on a packaging line carton erector, utilizing the 982 N push force to snap heavy cardboard flaps into position precisely.
Sorter Diverter Gate
Pivots a diverter gate on a logistics conveyor belt, relying on the FA front flange to withstand the torsional stress of redirecting parcels.
CNC Fixture Clamping
Actuates a secondary workholding clamp on a CNC machining center, where the adjustable cushion softens the impact on the jaw mechanism.
Is the Airtac SE50 Standard Cylinder SE50X70FA the Right Cylinder?
Selecting this 50 mm bore is ideal when you need 982 N of push force at 0.5 MPa. If your application requires less energy, stepping down to the 40 mm bore yields 628 N of push, while moving up to the 63 mm bore provides 1559 N for heavier demands. The FA front flange accessory handles high thrust loads directly through the face, but remember that a standard double-acting cylinder drifts when air pressure is lost; use a BSE rod lock variant if the load must be held securely during an exhaust or emergency stop.
Because the PT1/4 port and M16x1.5 rod thread match the standardized ISO 15552 footprint, this cylinder serves as a direct drop-in replacement for other ISO 15552 profile cylinders, simplifying retrofits. The 70 mm stroke operates well within the 30-800 mm/s speed range without requiring external side-load guides.
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 SE50X70FA FAQ
At 0.5 MPa, the SE50X70FA delivers 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 standardized ISO 15552 mounting dimensions make it a drop-in replacement for other profile cylinders with a PT1/4 port and M16x1.5 rod thread. However, this specific SKU does not include a built-in magnet, so it cannot host CMSE or DMSE position sensors without factory modification.
