About the Airtac SE80 Standard Cylinder SE80BX250S
The AirTAC SE80BX250S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty actuation, delivering a robust 2513 N push force at 0.5 MPa. Built with an extruded aluminum barrel free of external tie rods, the square profile mounts flush against machine frames, resisting corrosion while simplifying sensor placement along three integrated grooves. This specific configuration includes a SUS304 stainless steel rod (code B) for superior resistance in washdown or corrosive environments.
Equipped with a built-in magnet (code S), the cylinder seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune the deceleration of the 25 mm rod via a set screw, effectively softening hard end stops during high-speed 30-800 mm/s operations. It operates reliably between 0.15-1.0 MPa and utilizes PT3/8 ports for optimal air flow.

Where the Airtac SE80 Standard Cylinder SE80BX250S Is Used
Corrugated Box Forming
Drives the folding mechanism on high-speed packaging lines, utilizing the 2513 N push force and SUS304 rod to withstand dusty, humid cardboard processing environments.
Press Brake Backgauge
Positions sheet metal backstops on bending equipment with a 250 mm stroke, relying on DMSE electronic sensors to confirm gauge positioning under heavy vibration.
Bottling Plant Diverter
Actuates routing gates on beverage conveyor lines, where the stainless steel rod prevents washdown chemicals from degrading the actuator's dynamic seal.
Is the Airtac SE80 Standard Cylinder SE80BX250S the Right Cylinder?
Selecting the SE80BX250S places you in a high-output class, generating 2513 N of push at 0.5 MPa. If your application requires less force and a smaller footprint, stepping down to the 63 mm bore yields 1559 N push, whereas scaling up to the 100 mm bore provides a substantial 3927 N push. Because this model features a 250 mm stroke, it remains within standard dimensions but approaches the threshold where side loading becomes a concern; ensure an external guide supports the load to prevent rod-bearing bending. As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for competing standard cylinders, matching the 80 mm bore, 250 mm stroke, PT3/8 port, and standard mounting accessories. Note that while the adjustable cushion decelerates the piston, it does not lock the load—if air pressure is lost, 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 SE80BX250S FAQ
At 0.5 MPa, the SE80BX250S generates 2513 N of push force and 2268 N of pull force due to the single-rod design. At 0.7 MPa, the push force increases to 3518 N. The maximum push force is 513 kgf when operated at the 1.0 MPa pressure limit.
No, the adjustable air cushion at both ends only decelerates the piston near the stroke limits; it is not a braking mechanism. If your application must hold a vertical or suspended load without live air pressure, you must pair it with an external pilot-operated check valve or use the AirTAC BSE rod lock variant.
