About the Airtac SE50 Standard Cylinder SE50X90S
The AirTAC SE50X90S is a double-acting single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while keeping the standardized ISO 15552 footprint.
This 50 mm bore, 90 mm stroke unit includes a built-in magnet (-S) for direct integration with AirTAC CMSE reed and DMSE electronic position sensors. Field-adjustable air cushioning at both end caps allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50X90S Is Used
Carton Erector Flap Folding
Drives the folding arms on continuous carton packaging lines, utilizing the 90 mm stroke to tuck flaps rapidly while the adjustable cushion prevents jarring at the end of each 30-800 mm/s cycle.
Belt Conveyor Diverter Gate
Actuates routing flaps on parcel sortation conveyors, providing 982 N of push at 0.5 MPa to reliably deflect heavy cardboard boxes into secondary chutes without bouncing.
CNC Lathe Chuck Guard
Opens and closes the safety interlock door on CNC turning centers, using the integrated magnet to trigger DMSE electronic sensors that confirm the guard is fully clear before spindle startup.
Is the Airtac SE50 Standard Cylinder SE50X90S the Right Cylinder?
If 982 N of push at 0.5 MPa is excessive for your payload, stepping down to the 40 mm bore drops the output to 628 N. Conversely, heavier fixtures requiring more authority should step up to the 63 mm bore, which provides 1559 N of push. Because this is a double-acting cylinder, it relies on continuous air pressure to cycle and will drift if supply is lost—it is not a position-holding lock.
For retrofits, the SE50X90S is dimensionally interchangeable per ISO 15552, accepting standard 50 mm mounting accessories like FA front flanges or LB foot brackets. It uses a PT1/4 port and a 20 mm rod with an M16x1.5 thread. The integrated magnet enables drop-in CMSE or DMSE sensor installation without external hardware.
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 SE50X90S FAQ
