About the Airtac SE50 Standard Cylinder SE50X1800S
The AirTAC SE50X1800S is a double-acting single-rod ISO 15552 profile cylinder engineered for long-reach tasks, providing a robust 982 N push 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. Because this 1800 mm stroke exceeds the 1200 mm standard catalog maximum, it is manufactured as a made-to-order unit.
Equipped with a built-in magnet (-S), this unit seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune the deceleration of the piston via a set screw, softening hard end stops during high-speed travel. It operates efficiently at speeds between 30-800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50X1800S Is Used
Pallet Transfer Line
Drives the 1800 mm extension on a packaging conveyor to push heavy pallets between robotic cells, utilizing the 982 N push force to overcome initial friction.
Textile Drying Oven
Actuates a 1.8 meter guide frame inside a textile drying oven, relying on the DMSE electronic sensor to confirm full extension under high-temperature conditions.
Automated Storage Retrieval
Extends a tray extractor arm deep into high-density storage racks, where the extended stroke and adjustable end cushions prevent harsh impacts on the shelving structure.
Is the Airtac SE50 Standard Cylinder SE50X1800S the Right Cylinder?
Selecting this 50 mm bore makes sense when your application demands the 982 N push at 0.5 MPa but cannot fit a larger unit; if you need less force, stepping down to the 40 mm bore yields 628 N, while stepping up to the 63 mm bore provides 1559 N. At 1800 mm, the unsupported stroke length imposes significant leverage on the rod bearing, so an external guide is strongly recommended to prevent bending and premature seal wear. Furthermore, this cylinder cannot hold a load if air pressure is lost—the cushion only decelerates the piston near stroke end, so integrate a BSE rod lock for fail-safe holding. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, matching the standardized mounting interface, PT1/4 port, and M16x1.5 rod thread.
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 SE50X1800S FAQ
This 50 mm bore cylinder delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, the push force is 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
