About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1850
The AirTAC SC200X1850 is a large-bore double-acting pneumatic cylinder engineered for applications demanding extreme linear travel. With a 200 mm bore and an extended 1850 mm stroke, this model generates a substantial 15708 N of push force at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy-duty material handling and large-scale actuation.
This tie-rod cylinder features a robust 40 mm diameter piston rod and an adjustable air cushion of 33 mm to decelerate the piston smoothly at the end of its travel. The total body length is 244 mm, and with the 1850 mm stroke, the extended length reaches 2094 mm. As a non-standard stroke exceeding the typical 1500 mm maximum, this unit is a made-to-order genuine AirTAC product configured with standard PT ports and TPU seals for operation in ambient temperatures from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1850 Is Used
Long-Stroke Material Pusher
Provides the 1850 mm linear travel needed to push large panels or heavy pallets completely off a conveyor line or into a staging area with 15.7 kN of force at 0.5 MPa.
Agricultural Equipment Actuation
Controls large gates, chutes, or diverters on harvesters and processing equipment, using its 28 kN peak force to handle dense material flows reliably in dusty conditions.
Heavy-Duty Clamping & Forming
Applies sustained, high-force clamping for large-scale wood laminating or metal forming presses, where the 1850 mm stroke accommodates deep draw or multi-part fixture requirements.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1850 the Right Cylinder?
Select the SC200X1850 when your application requires a force of roughly 15.7 kN at standard shop air pressure. If your load demands a higher force capacity, stepping up to the SC250 bore provides 24544 N at 0.5 MPa. For a lighter, more compact solution, the SC160 bore offers 10053 N at the same pressure.
For an 1850 mm stroke, managing side loading is critical to prevent rod bending and premature bearing wear. An external guide rail or a self-guided unit should be used to absorb any lateral forces, ensuring the rod is only subjected to pure axial thrust. When replacing this cylinder, ensure the new unit matches the 200 mm bore, 1850 mm stroke, PT port thread, basic mounting configuration, and the absence of a built-in magnet.

- ✓ 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 SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1850 FAQ
At 0.7 MPa operating pressure, the SC200X1850 provides a theoretical push force of 21991 N and a pull force of 15080 N. The maximum push force at 0.9 MPa is 28274 N.
No, 1850 mm is a non-standard, made-to-order stroke for the SC200 bore, as the maximum standard stroke is 1500 mm. For such a long stroke, an external guide mechanism is essential to prevent side loading on the 40 mm rod, which can cause bending and seal failure.
