About the Airtac SE80 Standard Cylinder SE80BX850S
The AirTAC SE80BX850S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics. It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, ramping up to 3518 N at 0.7 MPa. The 850 mm stroke is a made-to-order length exceeding the 1500 mm standard maximum, making this specific configuration ideal for specialized, long-reach machinery.
Built with a square extruded aluminum barrel free of external tie rods, this unit resists corrosion and mounts flush in tight spaces. The SUS304 stainless steel piston rod (material code B) provides excellent durability in washdown or mildly corrosive environments. A built-in magnet enables seamless integration with AirTAC CMSE reed and DMSE electronic position sensors for precise end-of-stroke detection.

Where the Airtac SE80 Standard Cylinder SE80BX850S Is Used
Palletizer Stretch Wrap Loop
Drives the vertical carriage in a pallet stretch wrapper, using the 850 mm stroke to raise the film roll over tall palletized goods while the SUS304 rod resists humid plant air.
Automated Crate Rejecter
Pushes heavy beverage crates off a high-speed conveyor line, leveraging 2513 N of push force at 0.5 MPa to reliably divert heavy loads without compressed air spikes.
Laboratory Washdown Station
Actuates a protective shield or sample transport arm in a washdown environment, where the SUS304 rod prevents corrosion from frequent chemical cleaning.
Is the Airtac SE80 Standard Cylinder SE80BX850S the Right Cylinder?
In this 80 mm bore class, the cylinder provides 2513 N push at 0.5 MPa. If your application requires less force, stepping down to the 63 mm bore yields 1559 N, while stepping up to the 100 mm bore provides 3927 N for heavier loads. Because this is an 850 mm stroke, the unsupported length increases the risk of rod-bearing bending under side loads; an external guide rail is strongly recommended to prevent premature seal wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders, utilizing standard mounting hardware. Note that the field-adjustable air cushion at both ends only decelerates the piston near the stroke limits; it does not hold a load. If unpowered drift is a safety concern, specify a 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 SE80 Standard Cylinder SE80BX850S FAQ
This 80 mm bore cylinder features a PT3/8 port and a 25 mm diameter SUS304 rod. It generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, 3518 N of push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa.
The -S magnet is specifically designed for AirTAC CMSE reed and DMSE electronic sensors. The field-adjustable air cushion at both ends softens end-of-stroke impacts but only decelerates the piston; it does not lock or hold the load when air pressure is removed.
