About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450TC
The AirTAC SC200X450TC is a large-bore double-acting pneumatic cylinder engineered for heavy-duty linear applications requiring a 450 mm stroke. With a 200 mm piston, it generates a substantial 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa, placing it in a high-force class for pressing, clamping, and lifting heavy loads.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to pivot during operation to accommodate angular motion. The 40 mm diameter piston rod and 33 mm adjustable air cushion at each end ensure robust load handling and smooth deceleration, while the PT3/4 port threads provide ample air flow for responsive cycling.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450TC Is Used
Heavy-Duty Material Handling
Pivoting lift-and-tilt stations on conveyor lines use the trunnion-mounted SC200X450TC to reorient heavy pallets or engine blocks between processes.
Industrial Pressing & Forming
Delivers up to 28274 N of force for pressing bearings, forming sheet metal, or operating clinching tools in automotive assembly cells.
Agricultural Equipment Actuation
Controls large chutes, gates, or boom adjustments on harvesters and spreaders, where the trunnion mount absorbs the machine's vibration and articulation.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450TC the Right Cylinder?
Select the SC200X450TC when your application demands a pivoting mount and forces in the 15000-28000 N range. If your load requires even greater force, step up to the SC250 bore (24544 N push at 0.5 MPa); for a lighter, more compact solution, the SC160 bore offers 10053 N. At a 450 mm stroke, ensure the rod is not subjected to side loading—the 40 mm rod can bend under off-axis forces. For such cases, couple the cylinder with an external guide rail or consider a guided cylinder unit. When replacing an existing cylinder, match all five critical points: 200 mm bore, 450 mm stroke, PT3/4 port thread, centre trunnion (TC) mount, and the absence of a 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 SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450TC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 15708 N pushing force and 15080 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No, the AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC200 tie-rod cylinder with matching stroke, PT port, and TC trunnion mount.
