About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75TC
The AirTAC SC200X75TC is a double-acting tie-rod cylinder delivering a substantial 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa). With a 200 mm bore and a 75 mm stroke, this model is built for short, high-force linear movements in heavy industrial machinery.
This variant comes factory-equipped with a TC centre trunnion mount (supplied with TCM1 bracket, order code F-SC200TC), allowing the cylinder body to pivot during operation. The 40 mm diameter piston rod and 33 mm adjustable air cushion at each end provide robust guidance and smooth deceleration for heavy payloads.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75TC Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing force needed for short-stroke forming, stamping, or die-casting tool movements in metalworking plants.
Pivoting Conveyor Gate
The TC centre trunnion mount allows the cylinder to swing, making it ideal for actuating heavy diverter gates or chutes on bulk material conveyors.
Industrial Lift Table Tilt
Used in pairs to control the tilt function on heavy-duty scissor lift tables or large component positioners, where the trunnion mount absorbs the arcing motion.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75TC the Right Cylinder?
For applications requiring slightly less force, the 160 mm bore SC160 series provides 10053 N at 0.5 MPa. If your load demands this force class but a longer working stroke, the SC200 supports standard strokes up to 1500 mm. When replacing an existing cylinder, match five key points: 200 mm bore, 75 mm stroke, PT port thread, TC centre trunnion mounting, and the non-magnetic piston configuration. Always use an external guide or guided cylinder if the rod will experience significant side loading, even on short strokes, to protect the rod bearing and seals.
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 SC200X75TC FAQ
At the standard operating pressure of 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, push force increases to 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
The TC suffix indicates the cylinder is supplied with a centre trunnion for pivoting applications. For rigid mounting, you would select a different mounting code like LB (foot mount) or FA/FB (flange mount). The trunnion is integral to this specific model code and should be used for applications where the cylinder body needs to swing through an arc.
