About the Airtac SE40 Standard Cylinder SE40BX650S
The AirTAC SE40BX650S is a double-acting single-rod profile cylinder built to ISO 15552 standards, delivering a push force of 628 N at 0.5 MPa and a maximum of 128 kgf at 1.0 MPa. It features a SUS304 stainless steel piston rod engineered specifically for corrosive environments and washdown duty. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting external corrosion.
This 650 mm stroke unit includes a built-in magnet for non-contact position sensing using AirTAC CMSE reed or DMSE electronic switches. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-800 mm/s cycling.

Where the Airtac SE40 Standard Cylinder SE40BX650S Is Used
Medical Device Washdown
Lifts and lowers stainless steel trays in an autoclave; the SUS304 rod resists high-humidity corrosion while providing 528 N of retract pull at 0.5 MPa.
Packaging Line Diverter
Pushes cartons across a 650 mm transfer gap at 30-800 mm/s, using the built-in magnet and DMSE sensors to confirm full extension.
Textile Bleaching Gate
Actuates a chemical-resistant diverter gate in a textile mill, utilizing the tie-rod-free extruded profile to prevent chemical pooling.
Is the Airtac SE40 Standard Cylinder SE40BX650S the Right Cylinder?
When sizing this 40 mm bore actuator, evaluate your force margins: stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up to a 50 mm bore increases it to 982 N. This SE40BX650S configuration uses a PT1/4 port, a 16 mm rod, and the standard ISO 15552 mounting interface, ensuring direct dimensional interchangeability for retrofits. For stroke lengths of 650 mm, the extended piston rod is highly susceptible to side-load bending; always support the load with an external linear guide to prevent rod-bearing wear.
Note that the adjustable pneumatic cushion only decelerates the piston near stroke end and does not act as a braking mechanism. If your application must hold a vertical load without live air pressure, integrate an external rod lock like the AirTAC BSE series or a pilot-operated check valve.
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 SE40 Standard Cylinder SE40BX650S FAQ
The 40 mm bore generates a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force is 879 N. The maximum push force is 128 kgf at 1.0 MPa. It features a PT1/4 port, a 16 mm SUS304 rod, and operates at speeds between 30-800 mm/s.
Yes, the SE40BX650S is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other ISO 15552 profile cylinders using existing mounting hardware like FA front flanges or LB foot brackets, provided the 650 mm stroke and PT1/4 port match your pneumatic layout.
