About the Airtac SE100 Standard Air Cylinder SE100BX840SH
The AirTAC SE100BX840SH is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding washdown and high-temperature environments. Built with a SUS304 stainless steel rod and FKM Viton seals, it operates reliably up to 150 C while delivering 3927 N of push force at 0.5 MPa. This specific configuration features an 840 mm stroke, exceeding the 1500 mm standard maximum for this bore, making it a non-standard, made-to-order unit.
The extruded aluminum barrel design omits external tie rods entirely, yielding a compact, flush-mounting body that resists corrosion and simplifies sensor placement along three integrated grooves. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when cycling heavy loads at speed. The built-in magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic position sensing.

Where the Airtac SE100 Standard Air Cylinder SE100BX840SH Is Used
Autoclave Door Actuation
Leverages the FKM Viton seals and SUS304 rod to withstand 150 C ambient heat and steam while providing the 3927 N push force required to seal heavy pressure vessel doors.
Food Washline Diverter
Utilizes the corrosion-resistant stainless steel rod and tie-rod-free aluminum profile to push heavy product diverters across an 840 mm stroke in high-pressure washdown zones.
Composite Press Ejection
Applies the 5497 N push force at 0.7 MPa to eject cured composite panels from heated molds, relying on the field-adjustable cushioning to absorb kinetic energy at the end of the long stroke.
Is the Airtac SE100 Standard Air Cylinder SE100BX840SH the Right Cylinder?
This 100 mm bore generates 3927 N push and 3681 N pull at 0.5 MPa (up to 5497 N push at 0.7 MPa, max 801 kgf at 1.0 MPa). If your application requires less force, stepping down to the 80 mm bore yields 2513 N push at 0.5 MPa; conversely, moving up to the 125 mm bore provides 6136 N push. Because this unit features an 840 mm stroke, the unsupported rod length is substantial—long strokes increase the risk of rod-bearing bending under side load, so an external guide rail is strongly recommended to prevent premature seal wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, allowing you to use existing mounting hardware and drop it directly into a retrofit. Ensure your pneumatic supply is filtered to 40 um and prepare for a PT1/2 port connection. Remember that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking mechanism, so loads will drift if air pressure is lost.
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 SE100 Standard Air Cylinder SE100BX840SH FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force is 5497 N, with an absolute maximum push of 801 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, and the FKM Viton seals extend the operating temperature range to 150 C.
Yes, the SE profile barrel is dimensionally interchangeable per ISO 15552, meaning it serves as a drop-in replacement for other ISO 15552 cylinders using standard mounting accessories. However, the built-in adjustable air cushion only decelerates the piston near stroke end; it does not hold or lock a load. If you need position holding without live air pressure, you must use a BSE rod lock or an external pilot-operated check valve.
