About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1050
The AirTAC SC200X1050 is a double-acting tie-rod cylinder delivering substantial linear force for heavy-duty industrial automation. With a 200 mm bore operating at 0.5 MPa, this model generates 15708 N of push force, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa, driven by a rigid 40 mm diameter piston rod.
This 1050 mm stroke unit falls within the standard stroke range for the SC200 bore, which extends up to 1500 mm. The cylinder features a 33 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly, and its body length A is 244 mm, resulting in a total extended length of approximately 1294 mm. The standard PT3/4 port thread ensures straightforward pneumatic connection.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1050 Is Used
Heavy Pallet Lifting
Provides the 15+ kN force needed to elevate fully loaded industrial pallets in a scissor lift or vertical staging system, with the 1050 mm stroke offering substantial vertical travel.
Large Component Clamping
Applies high, controlled clamping pressure to secure large weldments or castings in a machining fixture, using the adjustable cushion to gently contact the part before full force is applied.
Log or Board Transfer
Pushes heavy timber or composite boards laterally off a main conveyor line, where the long stroke and high force capacity are essential for moving dense, oversized materials.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1050 the Right Cylinder?
Select the SC200 when your application requires a push force in the 15-28 kN range at typical industrial pressures. If your load demands less force, stepping down to the SC160 bore provides 10053 N at 0.5 MPa, potentially reducing air consumption and physical footprint. For strokes of this length, always verify the rod bearing's capacity to handle any side loading; an unsupported 40 mm rod extending over a meter can be subject to bending moments under eccentric loads.
For a direct replacement, match five key specifications: a 200 mm bore, 1050 mm stroke, PT3/4 port thread, the basic mounting configuration (no integrated bracket), and the absence of a built-in magnet. This ensures dimensional and performance interchangeability with an existing AirTAC SC200X1050 tie-rod cylinder. For applications with significant side force, consider adding an external linear guide or switching to a guided cylinder assembly.

- ✓ 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 SC200X1050 FAQ
At 0.7 MPa operating pressure, the theoretical push force output of the 200 mm bore SC cylinder is 21991 N. The pull force on the retract stroke at the same pressure is 15080 N, due to the area reduction from the 40 mm piston rod.
No. The SC200X1050 is a standard double-acting pneumatic cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop under load. To safely hold a load without live pressure, you must integrate an external mechanical rod lock, a pilot-operated check valve, or a dedicated brake unit into the system.
