About the Airtac SE40 Standard Cylinder SE40BX450S
The AirTAC SE40BX450S is a double-acting single-rod profile cylinder built to the ISO 15552 dimension standard. It delivers 628 N of push force at 0.5 MPa and utilizes a 40 mm bore with a 450 mm stroke. The extruded aluminum barrel lacks external tie rods, yielding a flush, corrosion-resistant body that simplifies direct mounting to machine frames.
This specific configuration features a SUS304 stainless steel rod (option B) for corrosive and washdown environments, paired with a built-in magnet (option S) for position sensing. The integrated magnet triggers AirTAC CMSE reed and DMSE electronic switches housed in the sensor grooves on three sides of the body, while field-adjustable air cushions at both ends absorb kinetic energy near stroke extremes.

Where the Airtac SE40 Standard Cylinder SE40BX450S Is Used
Bottling Line Diverter
Routes plastic containers on a washdown conveyor using the 628 N push force and SUS304 rod to withstand caustic cleaning chemicals.
Pallet Strapping Press
Tensions and seals strapping around corrugated pallets, relying on the 450 mm stroke to clear tall loads before cycling.
Lab Sample Dispenser
Actuates a metering valve for chemical reagents, using the DMSE electronic sensor to confirm full extension without contamination.
Is the Airtac SE40 Standard Cylinder SE40BX450S the Right Cylinder?
This 40 mm bore generates 628 N push at 0.5 MPa; if your load requires less force, step down to the 32 mm bore (402 N push), or step up to the 50 mm bore (982 N push) for heavier demands. The PT1/4 port and 450 mm stroke match standard ISO 15552 footprints, allowing a direct retrofit for existing hardware. Because the stroke is 450 mm, the unsupported rod length increases bending stress on the front bearing—use an external guide to prevent side-load wear.
Remember that the adjustable air cushion only decelerates the piston near the end of travel; it does not hold the load if air pressure drops. For position-holding safety during exhaust or valve centering, pair this cylinder with a BSE rod lock or an external 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 SE40BX450S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it provides 879 N push. The maximum push is 128 kgf at 1.0 MPa, and the operational speed ranges from 30-800 mm/s.
Yes, the SE40BX450S is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards, meaning it shares the exact same mounting footprint and PT1/4 port locations for direct replacement, provided your mounting accessory and stroke length match.
