About the Airtac SE50 Standard Cylinder SE50BX400S
The AirTAC SE50BX400S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 50mm bore and 400mm stroke. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, peaking at 1374 N push at 0.7 MPa. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal mechanics.
This specific configuration integrates a SUS304 stainless steel rod (code B) for superior resistance in washdown and corrosive environments. The built-in magnet (-S) enables seamless position detection using AirTAC CMSE reed or DMSE electronic sensors. Furthermore, the field-adjustable air cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration via a set screw, softening hard mechanical stops to extend component lifespan.

Where the Airtac SE50 Standard Cylinder SE50BX400S Is Used
Flow Wrapper End-Sealing
Drives the 400mm stroke to actuate sealing jaws on continuous flow wrappers, utilizing the 982 N push force to crimp packaging film while the SUS304 rod withstands washdown cycles.
Pallet Divert and Stop Gate
Extends across a conveyor lane to sort heavy pallets, relying on the adjustable air cushion to decelerate the 50mm bore piston smoothly and prevent impact damage to the load.
Chemical Reagent Dispensing
Positions dosing valves over mixing vats in corrosive environments, where the SUS304 stainless steel rod provides necessary chemical resistance and the -S magnet tracks exact fill positions.
Is the Airtac SE50 Standard Cylinder SE50BX400S the Right Cylinder?
When sizing this 50mm bore actuator, evaluate your force margins against the 982 N push at 0.5 MPa. If your application requires less energy, stepping down to the 40mm bore yields 628 N of push, while stepping up to the 63mm bore provides 1559 N for heavier payloads. Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. For position holding without live pressure, consider the AirTAC BSE rod lock variant.
With a 400mm stroke, the 20mm rod and M16x1.5 thread carry significant side-load potential at full extension. To prevent rod-bearing bending and premature seal wear, utilize an external guide rail to support the load independently of the piston rod. The PT1/4 port and standardized ISO 15552 mounting interface ensure it serves as a direct replacement for other ISO 15552 cylinders, sharing standard FA, LB, or TC mounting accessories seamlessly.
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 SE50BX400S FAQ
This 50mm bore cylinder delivers 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. The operational speed range is 30-800 mm/s.
Yes. The SE50BX400S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint, PT1/4 port locations, and M16x1.5 rod thread of other ISO 15552 profile cylinders for direct retrofitting.
