About the Airtac SE40 Standard Cylinder SE40BX650SN
The AirTAC SE40BX650SN is a double-acting single-rod ISO 15552 profile cylinder engineered for demanding 650mm stroke applications. It generates 628N of push force and 528N of pull force at 0.5 MPa, peaking at a 128kgf maximum push at 1.0 MPa. The extruded aluminum barrel design omits external tie rods entirely, yielding a compact, corrosion-resistant body that mounts flush into tight machine envelopes while resisting mechanical degradation.
Built specifically for washdown and corrosive environments, this variant features a SUS304 stainless steel rod paired with an NBR seal. The integrated magnet (-S) enables precise end-of-stroke detection using AirTAC CMSE reed or DMSE electronic sensors. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-stop deceleration via a set screw, softening impacts during high-speed 30-800mm/s operations.

Where the Airtac SE40 Standard Cylinder SE40BX650SN Is Used
Bottling Line Diverter
Uses the 650mm stroke and 628N push to deflect PET bottles between labeling lanes, where the SUS304 rod resists washdown moisture.
Palletizing Film Clamp
Extends fully to grip and stretch wrap film cores, relying on the adjustable cushion to soften the 30mm cushioning impact at high speeds.
Lab Sample Indexing
Drives a 650mm carrier rack in analytical equipment, using the -S magnet with DMSE solid-state sensors for precise positioning feedback.
Is the Airtac SE40 Standard Cylinder SE40BX650SN the Right Cylinder?
When sizing this 40mm bore actuator, consider stepping down to the 32mm bore (402N push at 0.5 MPa) for lighter loads, or up to the 50mm bore (982N push at 0.5 MPa) if your payload requires more thrust. Because this is a double-acting cylinder, it relies on continuous live air pressure to move; it does not hold position if air is exhausted or a valve centers. If your process demands fail-safe load holding, you must integrate an external pilot-operated check valve or adopt the AirTAC BSE rod-lock series.
At 650mm of stroke, the unsupported mass of the piston rod introduces a bending moment on the rod guide bearing under any side load. To prevent premature seal wear and bearing fatigue, always pair this long-stroke actuator with an external linear guide rail. This unit uses a PT1/4 port and a standard ISO 15552 mounting footprint, making it a direct dimensional direct replacement for other ISO 15552 cylinders 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 SE40 Standard Cylinder SE40BX650SN FAQ
