About the Airtac SE50 Standard Cylinder SE50X920S
The AirTAC SE50X920S 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 square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while retaining full dimensional interchangeability with other ISO 15552 cylinders.
Equipped with a built-in position magnet (-S), this unit directly supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable air cushions at both ends allow technicians to tune end-cap deceleration, softening hard mechanical stops during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50X920S Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets onto a secondary packaging line using its 982 N thrust, while the 920 mm stroke easily spans the required conveyor width.
Large Film Roll Unwind
Actuates the tensioning arm for wide packaging film rolls, using the integrated magnet to trigger DMSE electronic sensors for precise material feed control.
Automated Assembly Ejection
Ejects completed metal subassemblies from a machining cell, relying on the adjustable end cushions to absorb kinetic energy and prevent harsh impact at full extension.
Is the Airtac SE50 Standard Cylinder SE50X920S the Right Cylinder?
This 50 mm bore provides a 982 N push at 0.5 MPa; if your application requires less force, the 40 mm neighbor offers 628 N, while stepping up to the 63 mm bore yields 1559 N. Because this 920 mm stroke is a non-standard made-to-order length exceeding the 50 mm bore's 800 mm standard maximum, expect a tailored production run.
At 920 mm, the unsupported piston rod is highly susceptible to side-load bending and rod-bearing wear—an external guide rail is strongly recommended to prevent premature seal failure. Note that the adjustable cushion only decelerates the piston near stroke end and does not hold the load; if air pressure drops, the cylinder will drift, requiring a BSE rod lock for secure positioning.
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 SE50X920S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The standard operating speed ranges from 30-800 mm/s.
Yes, the SE50X920S shares the exact ISO 15552 / VDMA 24562 mounting interface and PT1/4 port size, making it a drop-in replacement for any standard ISO 15552 profile cylinder. Just ensure your mounting hardware and sensor grooves align with the standard extrusion.
