About the Airtac SE40 Standard Cylinder SE40BX500S
The AirTAC SE40BX500S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 40 mm bore and 500 mm stroke. It yields 628 N of push force at 0.5 MPa and integrates a built-in magnet for CMSE and DMSE position sensing. The SUS304 stainless steel rod equips this unit for corrosive washdown environments where standard carbon steel rods would degrade.
This actuator features a square extruded aluminum barrel without external tie rods, keeping the body compact and allowing flush mounting on machinery. The field-adjustable air cushioning at both ends lets you dial in end-of-stroke deceleration to absorb kinetic energy smoothly, rather than relying on a fixed rubber bumper.

Where the Airtac SE40 Standard Cylinder SE40BX500S Is Used
Stainless Bottling Line Diverter
Leverages the SUS304 rod and 628 N push force to actuate routing gates on beverage filling lines, enduring daily chemical washdowns without rod pitting.
Packaging Conveyor Reject Arm
Uses the 500 mm stroke to physically push misaligned cartons off a high-speed belt, relying on adjustable cushions to stop the 30 mm cushion stroke smoothly.
CNC Lathe Door Operator
Mounts flush via the extruded tie-rod-free barrel to open heavy machine tool doors, tracking full extension with a DMSE electronic sensor.
Is the Airtac SE40 Standard Cylinder SE40BX500S the Right Cylinder?
Stepping down to a 32 mm bore reduces the 0.5 MPa push to 402 N, while stepping up to a 50 mm bore increases it to 982 N. This 40 mm size fits perfectly when 628 N of extension thrust is required. Because the 500 mm stroke creates a long unsupported rod span, you must use an external guide to prevent rod-bearing bending under heavy side loads. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 cylinders using the same 40 mm bore, 500 mm stroke, PT1/4 port, and mounting hardware. Note that this standard cylinder does not hold loads when air is exhausted; if your application requires position holding without live pressure, consider the BSE rod lock variant.
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 SE40BX500S FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 879 N. The maximum push force is 128 kgf at 1.0 MPa.
Yes. The SE40BX500S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact same mounting footprint and PT1/4 port locations for a direct retrofit, provided you use the appropriate mounting accessory.
