About the Airtac SE63 Standard Cylinder SE63BX400S
The AirTAC SE63BX400S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 63 mm bore and 400 mm stroke. It delivers a robust 1559 N push force at 0.5 MPa, utilizing a PT3/8 port and a 20 mm rod with an M16x1.5 thread. Because this configuration uses a SUS304 stainless steel rod (code B), it is specifically tailored for corrosive environments and washdown duty where a standard carbon steel piston rod would fail prematurely.
The extruded aluminum barrel features a square profile completely free of external tie rods, which keeps the body compact, flush-mountable, and highly resistant to mechanical snagging. Integrated sensor grooves on three sides allow you to directly mount CMSE reed or DMSE electronic switches, leveraging the built-in S magnet for precise end-of-stroke detection. Furthermore, the field-adjustable pneumatic cushioning at both ends can be tuned via a set screw to smoothly decelerate the piston at high cycle speeds, preventing harsh end-cap impacts.

Where the Airtac SE63 Standard Cylinder SE63BX400S Is Used
Dairy Washdown Gate
Actuates diverter valves in food processing lines, utilizing the SUS304 stainless rod to withstand harsh chemical washdowns while providing 1559 N push force.
Marine Parts Sorter
Pushes saltwater-exposed marine components down a 400 mm stroke classification lane, relying on the corrosion-resistant rod and adjustable cushioning to prevent end-stop damage.
Chemical Film Roll Ejector
Ejects heavy rolls of packaging film from a coating machine, using the built-in S magnet and DMSE sensors to confirm ejection completion in automated PLC logic.
Is the Airtac SE63 Standard Cylinder SE63BX400S the Right Cylinder?
When sizing this actuator, consider stepping down to the 50 mm bore if your application requires less energy, as it yields 982 N of push at 0.5 MPa. Conversely, if your load demands more authority, the 80 mm bore provides 2513 N of push at 0.5 MPa. This 63 mm model strikes an excellent balance, but remember that a standard SE cylinder does not hold its position or load when air is exhausted or the valve is centered; the piston will drift. If your process requires true mid-locking or fail-safe holding, you must integrate an external rod lock or transition to the AirTAC BSE series.
With a 400 mm stroke, the unsupported length of the 20 mm rod increases its susceptibility to side-load bending and bearing wear. For any heavy offset loads or dynamic lateral forces encountered at this extension, always pair the cylinder with an external linear guide to prevent premature seal failure. As a dimensionally interchangeable ISO 15552 component, this cylinder serves as a direct replacement for other ISO 15552 cylinders, sharing standard mounting hardware and footprint dimensions without requiring custom 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 SE63 Standard Cylinder SE63BX400S FAQ
At 0.5 MPa, the SE63BX400S provides 1559 N of push force and 1402 N of pull force. When operating at 0.7 MPa, the push force increases to 2182 N. The maximum allowable push force is 318 kgf at 1.0 MPa.
