About the Airtac SE80 Standard Cylinder SE80BX250
The AirTAC SE80BX250 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty linear motion. It provides a robust 2513 N push force at 0.5 MPa alongside a 2268 N pull force, making it well-suited for high-inertia loads. Built with a square extruded aluminum barrel, this unit eliminates external tie rods to provide a flush, corrosion-resistant exterior that mounts cleanly in tight machinery spaces.
This specific configuration features a SUS304 stainless steel rod (material code B) for superior resistance to moisture and washdown chemicals. The bore utilizes a PT3/8 port and a 25 mm rod with an M20x1.5 thread. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard mechanical impacts without relying on fixed rubber bumpers.

Where the Airtac SE80 Standard Cylinder SE80BX250 Is Used
Palletizer Case Pusher
Drives heavy cardboard cartons onto shipping pallets, utilizing the 2513 N push force to overcome friction on guide rails without stalling.
Washdown Diverter Gate
Actuates stainless steel flow gates in food and beverage lines, where the SUS304 rod material prevents corrosion during daily chemical washdowns.
Press Brake Material Stop
Positions heavy-gauge steel sheet backstops in metal forming presses, relying on the 250 mm stroke and 3518 N thrust at 0.7 MPa for rigid placement.
Is the Airtac SE80 Standard Cylinder SE80BX250 the Right Cylinder?
Selecting this 80 mm bore makes sense when a 63 mm cylinder (1559 N push @0.5 MPa) lacks the thrust for your payload, but you want to avoid the bulk and higher air consumption of a 100 mm bore (3927 N push @0.5 MPa). Because this is a standard 250 mm stroke, the 25 mm rod and M20x1.5 thread provide substantial rigidity, but at this length the unsupported piston rod is susceptible to bending under lateral loads—always specify an external guide rail to prevent rod-bearing wear.
As a true ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders, sharing identical mounting interface dimensions and accessories. Note that this SKU lacks a position sensor magnet; if your sequence control requires end-of-stroke feedback, you must specify the -S option for CMSE or DMSE switch compatibility. Furthermore, the adjustable air cushion only decelerates the piston near stroke end and does not hold the load 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 SE80 Standard Cylinder SE80BX250 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N, with a maximum push capacity of 513 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the SE80BX250 is a standard double-acting cylinder and will drift if air pressure is lost or the control valve is centered. The adjustable air cushion only decelerates the piston near the end of stroke; it does not act as a brake. For position holding, you would need a BSE series rod lock or an external pilot-operated check valve.
