About the Airtac SE50 Standard Cylinder SE50BX900S
The AirTAC SE50BX900S is a double-acting single-rod profile cylinder built to the ISO 15552 / VDMA 24562 standard. It features a 50 mm bore and a 900 mm stroke, generating 982 N of push force at 0.5 MPa and up to 1374 N at 0.7 MPa. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant profile that mounts flush against machine frames.
This specific configuration includes a SUS304 stainless steel rod (code B) for corrosive or washdown environments, alongside a built-in magnet (code S) for position sensing. The integrated magnet interfaces directly with AirTAC CMSE reed and DMSE electronic switches fitted into the sensor grooves on three sides of the body. Field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration for the moving load.

Where the Airtac SE50 Standard Cylinder SE50BX900S Is Used
Palletizing Robot Ejection
Drives the 900 mm ejection stroke on a packaging line, utilizing the 982 N push force to clear folded cartons off a conveyor while the SUS304 rod resists occasional washdown overspray.
CNC Lathe Bar Feeder
Actuates a 900 mm support carriage for stock material, where the adjustable end cushions soften the impact of the extended mass and the built-in magnet triggers a DMSE sensor to confirm feed completion.
Food Processing Diverter
Pushes a sorting flap over a 900 mm travel distance in a food packaging facility, relying on the SUS304 stainless steel rod to withstand daily chemical washdowns without pitting.
Is the Airtac SE50 Standard Cylinder SE50BX900S the Right Cylinder?
Stepping up or down from this 50 mm bore depends on your force requirements: the smaller 40 mm bore provides 628 N of push at 0.5 MPa, while the larger 63 mm bore yields 1559 N. This SE50BX900S uses a PT1/4 port and a Ø20 mm rod with an M16x1.5 thread. Because it is a standard double-acting cylinder, it will drift if air pressure is lost or the valve is centered; use a BSE rod lock variant if the application requires strict position holding.
At 900 mm of stroke, the unsupported rod length increases the risk of side-load bearing wear and bending. Implementing an external guide rail is strongly recommended to prevent premature seal failure and rod deflection. As a true ISO 15552 cylinder, it serves as a dimensionally interchangeable direct replacement for other ISO 15552 profile cylinders without altering mounting hardware.
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 SE50BX900S FAQ
At 0.5 MPa, the SE50BX900S generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf when operated at the maximum rated pressure of 1.0 MPa.
Yes, the SE50BX900S is dimensionally interchangeable per ISO 15552 standards, meaning it can serve as a direct replacement for other ISO 15552 profile cylinders using the same mounting footprint and PT1/4 port size.
