About the Airtac SE40 Standard Cylinder SE40BX400SH
The AirTAC SE40BX400SH is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding environments. It generates 628 N of push force at 0.5 MPa and features a SUS304 stainless steel rod paired with a Viton (FKM) seal, expanding the operating temperature range up to 150 C for rigorous washdown or high-heat duty. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This 40 mm bore unit includes a built-in position magnet (code S) designed to interface directly with AirTAC CMSE reed and DMSE electronic sensors along its three integrated side grooves. Field-adjustable pneumatic cushioning at both stroke ends allows technicians to tune end-of-stroke deceleration via a set screw, softening impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE40 Standard Cylinder SE40BX400SH Is Used
Bottle Filler Divert Gate
Actuates a routing gate on a 150 C beverage line, utilizing the Viton seal and SUS304 rod to withstand daily caustic washdowns while providing 628 N of push force at 0.5 MPa.
Pallet Accumulation Stop
Raises a physical stop arm on a 400 mm stroke to halt pallets, relying on the adjustable air cushions to soften the impact of rapidly cycling loads at speeds up to 800 mm/s.
Film Roll Tensioning Arm
Maintains precise tension on a packaging web, using the integrated magnet and DMSE electronic sensors to confirm arm position across the extended stroke.
Is the Airtac SE40 Standard Cylinder SE40BX400SH the Right Cylinder?
Selecting this 40 mm bore involves sizing against its neighbors: if your application requires less force, the 32 mm bore offers 402 N of push at 0.5 MPa, while stepping up to the 50 mm bore yields 982 N. The PT1/4 port and M12x1.25 rod thread provide standardized ISO 15552 mounting, making it a direct replacement for other ISO 15552 cylinders without altering your existing footprint or hardware.
Because this model features a 400 mm stroke, the extended piston rod is susceptible to bending under lateral loads; always incorporate an external guide mechanism to prevent rod-bearing damage. Furthermore, a standard double-acting cylinder drifts when air pressure is lost or a valve is centered—this unit will not hold a load vertically without live pressure, so integrate a BSE rod lock or pilot-operated check valve if position holding is required.
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 SE40BX400SH FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N, with a maximum push capacity of 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, its standardized ISO 15552 mounting dimensions make it a direct retrofit for other profile cylinders. However, it does not hold position unpowered; the adjustable air cushion only decelerates the piston near stroke end and is not a locking mechanism. Use an external rod lock for holding.
