About the Airtac SE80 Standard Cylinder SE80BX350
The AirTAC SE80BX350 is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver a robust 2513 N push force at 0.5 MPa. Featuring an 80 mm bore and 350 mm stroke, it utilizes a square extruded aluminum barrel that entirely eliminates external tie rods. This clean-profile design not only resists corrosion but allows for flush mounting against machine frames, saving valuable space in tight cells.
This specific SKU is built with a SUS304 stainless steel rod (option B) for superior resistance to moisture and corrosive washdowns. It operates at speeds from 30-800 mm/s and features field-adjustable air cushioning at both ends. Because this model lacks the -S magnet code, it is not wired for CMSE or DMSE position sensing out of the box, relying instead on its mechanical end-of-stroke reliability.

Where the Airtac SE80 Standard Cylinder SE80BX350 Is Used
Pallet Diverters
Drives heavy pallet lane diverters in high-throughput distribution centers, utilizing the 2513 N push force at 0.5 MPa to reliably shift loaded skids without hesitation.
Corrugated Box Formers
Actuates the main folding arms on corrugated box formers, where the SUS304 stainless rod withstands humid production environments and occasional washdowns.
Injection Mold Ejectors
Provides the extended 350 mm ejection stroke to push cured plastic parts clear of injection molding presses, safely clearing the platen area for robotic pickup.
Is the Airtac SE80 Standard Cylinder SE80BX350 the Right Cylinder?
Selecting this 80 mm bore makes sense when you need substantial thrust; if you are scaling down, the 63 mm bore provides 1559 N push at 0.5 MPa, while stepping up to the 100 mm bore yields 3927 N. With a 350 mm stroke, the 25 mm rod and internal bearing face bending loads under side thrust, so an external guide rail is strongly recommended to prevent premature seal wear. As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, matching the PT3/8 port and standardized mounting accessories without requiring custom brackets. Note that the adjustable end cushions decelerate the piston near stroke end but do not lock the load; if air pressure drops, the rod will drift, requiring a BSE rod lock for secure holding.
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 SE80BX350 FAQ
This 80 mm bore cylinder uses a PT3/8 port and generates 2513 N push / 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.
No, the adjustable air cushions only decelerate the piston near the end caps and do not act as a brake. If you need to hold a vertical load without live air pressure, you must use a BSE rod lock variant or an external pilot-operated check valve.
