About the Airtac SC50 Standard Cylinder SC50X1900S
The AirTAC SC50X1900S is a double-acting tie-rod cylinder with a 50 mm bore and an extended 1900 mm stroke, which exceeds the standard maximum of 1200 mm for this bore size, making it a non-standard, made-to-order configuration. It generates a theoretical push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with an M16x1.5 male thread.
This model includes a built-in magnet (-S suffix), allowing the direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for reliable, contactless position detection. The cylinder body has a length of 150 mm, and with the full 1900 mm stroke, the total extended length reaches 2050 mm, requiring careful support planning for the long rod.

Where the Airtac SC50 Standard Cylinder SC50X1900S Is Used
Long-Reach Material Pusher
Ideal for a long-stroke pusher in a warehouse conveyor system, where the 1900 mm stroke can transfer large items between distant lanes, with sensors confirming full extension and retraction.
Automated Spray Coating Boom
Extends and retracts a spray nozzle boom over a 1.9-meter path in a finishing line. The built-in magnet provides precise position feedback at multiple points along the stroke for even coating application.
Large-Format Press Ejection
Used to eject large panels from a forming press, where the 982 N push force at 0.5 MPa is sufficient to clear the part, and the long stroke fully removes it from the die area for robotic pickup.
Is the Airtac SC50 Standard Cylinder SC50X1900S the Right Cylinder?
Select the SC50X1900S when your application requires a 50 mm bore with a very long 1900 mm stroke and integrated position sensing. For applications needing more force, stepping up to the SC63 bore provides 1559 N of push force at 0.5 MPa. For a shorter, standard-stroke alternative, the SC50 series offers strokes up to 1200 mm from standard inventory.
For a stroke of this length, external guidance is critical. The long, 20 mm diameter rod is susceptible to bending and buckling under side loads. A rigid external guide mechanism or a self-guided cylinder is strongly recommended to protect the rod bearings and ensure reliable, long-term operation. For a direct replacement, ensure the new cylinder matches this model's 50 mm bore, 1900 mm stroke, PT1/4 port thread, basic mounting, and integrated magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X1900S FAQ
The theoretical push force at 0.5 MPa (5 bar) is 982 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The pull force on the retract stroke is lower due to the rod area, delivering 825 N at 0.5 MPa.
Yes, it is strongly recommended. The 20 mm diameter rod on a 50 mm bore cylinder is not designed to support significant side loads, especially when fully extended to 1900 mm. An external guide or a guided cylinder assembly is necessary to prevent rod bending, bearing wear, and premature seal failure.
