About the Airtac SE40 Standard Cylinder SE40BX650SLB
The AirTAC SE40BX650SLB is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding pneumatic tasks. It generates 628 N of push force at 0.5 MPa and features a PT1/4 port paired with a 16 mm rod. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while retaining the standardized ISO 15552 footprint for direct retrofitting.
This specific configuration utilizes a SUS304 stainless steel rod for superior resistance in washdown and corrosive settings, and includes a built-in magnet for CMSE and DMSE position sensing. The 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 cycles.

Where the Airtac SE40 Standard Cylinder SE40BX650SLB Is Used
Bottling Line Diverters
With 628 N push at 0.5 MPa and a 650 mm reach, this cylinder easily routes plastic bottles between labeling stations, while the SUS304 rod shrugs off daily washdowns.
Automated Saw Feeder
The 650 mm stroke provides ample travel for pushing aluminum extrusions into a cutting saw, relying on the adjustable cushion to soften end-of-stroke impacts at speed.
Lab Sample Handling
The built-in magnet pairs with DMSE electronic sensors to verify sample rack positioning across a 650 mm span, benefiting from the smooth profile barrel design.
Is the Airtac SE40 Standard Cylinder SE40BX650SLB the Right Cylinder?
If mapping out your force requirements, the 40 mm bore sits right in the middle: step down to a 32 mm bore for 402 N push at 0.5 MPa, or move up to a 50 mm bore for 982 N push at 0.5 MPa. Because this is a 650 mm stroke, the extended 16 mm rod carries a higher risk of bending under side loads, so an external guide is strongly recommended to prevent premature rod-bearing wear. Remember that this plain SE cylinder will drift if air pressure is lost or the valve is centered; if your process requires true position holding without live pressure, consider the BSE rod-lock variant. To match this exact unit, specify the 40 mm bore, 650 mm stroke, PT1/4 port, LB foot mounting, SUS304 rod, and the -S magnet.
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 SE40BX650SLB FAQ
This 40 mm bore model delivers 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and reaches a maximum push of 128 kgf at 1.0 MPa operating pressure.
Yes, the SE40BX650SLB is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement using existing mounting hardware and LB foot brackets, provided the 650 mm stroke and PT1/4 port match your layout.
