About the Airtac SE80 Standard Cylinder SE80BX375S
The AirTAC SE80BX375S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty actuation. It delivers 2513 N of push force at 0.5 MPa and 3518 N at 0.7 MPa, utilizing an 80 mm bore and a 375 mm stroke. The extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific configuration features a SUS304 stainless steel rod (code B) for superior resistance to moisture and washdown chemicals. A built-in magnet (code S) enables position detection via AirTAC CMSE reed or DMSE electronic sensors. The field-adjustable air cushion at both ends can be tuned via a screw to decelerate the piston smoothly at high speeds, preventing hard end-stop impacts.

Where the Airtac SE80 Standard Cylinder SE80BX375S Is Used
Palletizer Flap Folder
Provides 2513 N push at 0.5 MPa to fold heavy corrugated cardboard flaps on automated palletizing lines, leveraging the SUS304 rod for washdown compatibility.
CNC Lathe Bar Feeder
Handles 375 mm stroke to push raw bar stock into spindles, relying on the field-adjustable air cushion to soften high-speed retraction impacts.
Bottling Line Diverter
Uses the built-in magnet with DMSE sensors to confirm gate position while diverting glass bottles, ensuring precise routing without tie-rod obstructions.
Is the Airtac SE80 Standard Cylinder SE80BX375S the Right Cylinder?
Select this 80 mm bore when an application requires substantial thrust—2513 N at 0.5 MPa push. If your load is lighter, stepping down to the 63 mm bore yields 1559 N push, whereas moving up to the 100 mm bore provides 3927 N push. Because this is a 375 mm stroke (a non-standard made-to-order length exceeding the 150 mm standard maximum), the 25 mm rod and M20x1.5 thread carry significant side-load leverage; an external guide is strongly recommended to prevent rod-bearing bending.
The SE80BX375S is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders using the same 80 mm bore, 375 mm stroke, PT3/8 port, and mounting accessory pattern. Remember that a plain SE cylinder does not hold its load when air is exhausted—the adjustable cushion only decelerates the piston near stroke end and is not a lock.
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 SE80BX375S FAQ
The 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa.
Yes, the SE80BX375S is dimensionally interchangeable per ISO 15552, matching standard 80 mm bore, 375 mm stroke, PT3/8 port, and mounting footprint dimensions for direct retrofit.
