About the Airtac SE50 Standard Cylinder SE50X770S
The AirTAC SE50X770S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a 982 N push at 0.5 MPa over a 770 mm stroke. Its square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. The integrated -S magnet enables direct position tracking with CMSE reed or DMSE electronic sensors housed cleanly in the body’s three sensor grooves.
To manage kinetic energy at the end of this long travel, the cylinder incorporates field-adjustable air cushioning at both ends. By turning a setscrew, technicians can tune the exhaust bleed to soften hard end-stops and prevent piston bounce, which is critical for maintaining cycle speed without shocking the payload.

Where the Airtac SE50 Standard Cylinder SE50X770S Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets onto a secondary packaging line using its 982 N thrust and 770 mm travel, relying on external guides to support the long stroke.
Carton Flap Folding
Drives a mechanical flap-folding arm on a continuous box erecting machine, using the -S magnet and DMSE sensors to confirm full extension before adhesive application.
Textile Beam Indexing
Shifts heavy fabric beams laterally across a weaving loom setup, utilizing the adjustable end cushions to gently stop the 770 mm traverse without jarring the delicate material.
Is the Airtac SE50 Standard Cylinder SE50X770S the Right Cylinder?
This 50 mm bore provides 982 N of push force at 0.5 MPa. If you need less output, the 40 mm neighbor offers 628 N; stepping up to the 63 mm bore yields 1559 N. Because the 770 mm stroke is unsupported over much of its length, the Ø20 mm rod and bearing face significant bending moments under side loads—an external guide rail is strongly recommended to prevent premature seal wear.
For retrofits, this cylinder is dimensionally interchangeable with other ISO 15552 profile cylinders, matching the 50 mm bore, 770 mm stroke, PT1/4 port, and standard mounting accessories. Note that the adjustable air cushion only decelerates the piston near stroke end; it does not lock the rod. If the machine loses air pressure, the load will drift, requiring a BSE rod lock or external pilot check valve 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 SE50 Standard Cylinder SE50X770S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
Yes, it is dimensionally interchangeable with any standard ISO 15552 profile cylinder of the same 50 mm bore and stroke. However, it cannot hold a load if air pressure is lost; the adjustable cushion only decelerates the piston near the end of travel. For position holding, use a BSE rod lock variant.
