About the Airtac SE50 Standard Cylinder SE50X850
The AirTAC SE50X850 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 and a maximum of 200 kgf at 1.0 MPa. Its extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion.
This 850 mm stroke unit operates at speeds from 30-800 mm/s and relies on a PT1/4 port with a 20 mm rod. Because this specific SKU lacks the -S magnet code, it is not equipped for CMSE or DMSE position sensing out of the box. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration for the long travel distance.

Where the Airtac SE50 Standard Cylinder SE50X850 Is Used
Pallet Divider Actuation
Separates heavy wood pallets on a packaging line using the 982 N push force across the 850 mm stroke to create distinct handling lanes.
Vertical Lift Gate
Raises and lowers a 50 kg materials handling safety gate, relying on the 200 kgf maximum output to overcome gravity during the long 850 mm travel.
Film Roll Ejector
Pushes completed shrink-wrap film rolls out of a winding station, utilizing the full 850 mm extension to clear the machinery footprint.
Is the Airtac SE50 Standard Cylinder SE50X850 the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm cylinder reduces the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore increases it to 1559 N. This SE50X850 is dimensionally interchangeable with other ISO 15552 cylinders, making it a direct retrofit using standard mounting accessories and its PT1/4 port.
Because the 850 mm stroke creates a long unsupported rod extension, side-load bending moments place significant stress on the rod bearing. An external guide mechanism is strongly recommended to prevent premature seal wear. Note that if air pressure is lost, this cylinder will drift and cannot hold a load; apply a BSE rod lock for static 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 SE50X850 FAQ
At 0.5 MPa, the SE50X850 provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N. The maximum rated push force is 200 kgf at 1.0 MPa.
