About the Airtac SE50 Standard Cylinder SE50X50SG
The AirTAC SE50X50SG is a double-acting, single-rod ISO 15552 profile cylinder delivering 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. It features a 50 mm bore, a 50 mm stroke, and a G1/4 BSPP port. The square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while resisting mechanical snags.
This specific configuration includes a built-in magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors, ensuring reliable end-of-stroke detection. The field-adjustable air cushioning at both ends allows technicians to tune the pneumatic deceleration via a set screw, softening hard end stops during high-speed cycling. The cushion only decelerates the piston near stroke end and does not lock or hold the load.

Where the Airtac SE50 Standard Cylinder SE50X50SG Is Used
Carton Erector Flaps
Drives the folding mechanism on packaging lines, utilizing its 982 N push force to snap heavy cardboard carton flaps into position securely before sealing.
Belt Diverter Gate
Powers a routing diverter on a conveyor belt system, using its 50 mm stroke and built-in DMSE sensor confirmation to push parcels smoothly onto secondary chutes.
PCB Test Fixture
Actuates an electronic test bed fixture, applying precise 825 N pull force to hold circuit boards against spring-loaded test pins during automated quality checks.
Is the Airtac SE50 Standard Cylinder SE50X50SG the Right Cylinder?
When sizing this 50 mm bore actuator, evaluate your exact force requirements: it provides 982 N push at 0.5 MPa. If your assembly requires less force, step down to the 40 mm bore, which yields 628 N of push at 0.5 MPa. If your mechanism demands higher thrust, the 63 mm bore offers 1559 N at 0.5 MPa. Because this is a double-acting cylinder, it does not hold its position if air pressure is lost or the valve is centered—the piston will drift, so a BSE rod lock is needed for secure holding.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, sharing standard mounting hardware. This SE50X50SG variant includes a G1/4 port thread, a built-in position-sensing magnet, and standard mounting brackets. At a 50 mm stroke, side-load stress on the rod bearing is minimal, but always ensure the load is guided externally to prevent premature seal 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.
