About the Airtac SC50 Standard Cylinder SC50X1900
The AirTAC SC50X1900 is a double-acting pneumatic cylinder with a 50 mm bore and an extended 1900 mm stroke, built for applications requiring a long reach. At the standard 0.5 MPa operating pressure, it provides a push force of 982 N, scaling up to 1767 N at the maximum 0.9 MPa, offering substantial linear power for its compact tie-rod design.
This model features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The 1900 mm stroke exceeds the standard maximum of 1200 mm for this bore, making it a non-standard, made-to-order item. The body length A is 150 mm, and the total extended length is approximately 2050 mm. Its adjustable pneumatic cushion softens end-of-stroke impact over a 21 mm cushion length.

Where the Airtac SC50 Standard Cylinder SC50X1900 Is Used
Long-Reach Material Pushing
Ideal for pushing heavy bins or pallets across wide conveyor transfer points where a long stroke is needed to clear the mechanism, utilizing its 1767 N max force.
Automated Gantry Tool Actuation
Provides the extended vertical or horizontal reach for a tooling head on a gantry system, such as a gluing nozzle or pick-and-place gripper over a large work envelope.
Agricultural Gate or Chute Control
Operates a large sliding gate or diverter chute on grain handling or sorting equipment, where the 1900 mm stroke is necessary for full open/close travel.
Is the Airtac SC50 Standard Cylinder SC50X1900 the Right Cylinder?
For applications needing a 50 mm bore but a shorter stroke, the standard SC50 series offers strokes up to 1200 mm, which are typically stocked. If the 982 N push force at 0.5 MPa is insufficient, stepping up to the 63 mm bore provides 1559 N at the same pressure. Conversely, the 40 mm bore delivers 628 N for a more compact solution.
Given the exceptionally long 1900 mm stroke, side-load management is critical. The 20 mm rod is susceptible to bending under lateral forces when fully extended. It is strongly recommended to use an external linear guide or rod support to prevent bearing damage and ensure reliable operation. For a direct replacement, match the 50 mm bore, 1900 mm stroke, PT1/4 port thread, basic mounting, and the absence of a magnet sensor.
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 SC50X1900 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
For a 1900 mm stroke, the rod is highly vulnerable to buckling and side-load bending. You must guide the load externally with a linear rail or rod support. Never apply a direct side load to the unsupported rod end, as this will quickly damage the rod bearing and seals.
