About the Airtac SE50 Standard Cylinder SE50X65S
The AirTAC SE50X65S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a push force of 982 N at 0.5 MPa. Its 65 mm stroke and square extruded aluminum barrel provide a compact, flush-mounting solution without external tie rods, reducing corrosion traps in tight machinery frames.
Equipped with a built-in magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection. The field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration, smoothly damping the 20 mm piston rod without relying on hard mechanical bumpers.

Where the Airtac SE50 Standard Cylinder SE50X65S Is Used
Carton Flap Folding
Drives the mechanical arms that fold corrugated carton flaps prior to hot-melt sealing, utilizing the 982 N push force to overcome cardboard stiffness within the 65 mm stroke.
Bottle Diverting Gate
Actuates a routing gate on a bottling conveyor, using the integrated magnet and DMSE sensor to confirm gate position before PET containers pass through.
Press Brake Stopper
Functions as an adjustable back-gauge stopper on a small sheet metal press brake, where the field-tuned air cushion softens the retraction impact to protect the gauge alignment.
Is the Airtac SE50 Standard Cylinder SE50X65S the Right Cylinder?
Selecting this 50 mm bore yields 982 N of push force at 0.5 MPa. If your application requires less thrust, stepping down to the 40 mm bore provides 628 N, while moving up to the 63 mm bore offers 1559 N for heavier payloads. This SE50X65S features a PT1/4 port and an M16x1.5 rod thread, making it dimensionally interchangeable with other ISO 15552 cylinders for direct retrofits.
Because it is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve centers; the piston will drift. For applications requiring position holding without live pressure, consider the BSE rod lock variant. The 65 mm stroke is short enough to avoid rod-bearing bending, but always ensure the load is guided externally to prevent side-load wear.
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 SE50 Standard Cylinder SE50X65S FAQ
The 50 mm bore provides a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, the push force is 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The fluid port size is PT1/4.
Yes, the SE50X65S shares the standardized ISO 15552 mounting dimensions, allowing it to serve as a drop-in replacement for other profile cylinders of the same bore and stroke. Its adjustable air cushion at both ends uses a needle screw to regulate exhaust flow, decelerating the piston near the end of travel rather than relying on a fixed bumper.
