About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X350TC
The AirTAC SC250X350TC is a heavy-duty double-acting tie-rod cylinder engineered for high-force industrial automation. With a 250 mm bore and 350 mm stroke, it generates a substantial 24544 N of push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure), making it suitable for pressing, lifting, and large-scale clamping operations.
This specific configuration includes a centre trunnion mount (TC), supplied with the TCM1 bracket (F-SC250TC), allowing the cylinder to pivot during actuation. The 50 mm diameter piston rod features an M42x2 male thread, and the unit includes an adjustable air cushion (40 mm length) to decelerate the massive 5006 kgf theoretical load smoothly. Operating on filtered air at 0.15-1.0 MPa, the standard TPU seals provide a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X350TC Is Used
Heavy Pressing & Forming
Delivers up to 44178 N of force at 0.9 MPa for stamping, riveting, or composite forming operations in durable goods manufacturing.
Pallet Lifting & Tipping
The centre trunnion mount allows the cylinder body to pivot, ideal for lifting and tipping heavy pallets or containers on a production line.
Large-Scale Clamping
Provides stable, high-force clamping for large weldments or structural assemblies, with an adjustable cushion to protect the tooling at end-of-stroke.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X350TC the Right Cylinder?
Select the SC250 when your application demands forces in the 24 kN class at standard plant pressure. If your load calculation falls closer to 15 kN, stepping down to a 200 mm bore (15708 N push at 0.5 MPa) may reduce air consumption and physical footprint. For strokes of 350 mm, ensure the rod is guided externally if any significant side load is present; the 50 mm rod is robust, but bending moments on a long unsupported stroke can damage the piston bearing and seals.
For a direct replacement, match five key attributes: 250 mm bore, 350 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the absence of a magnet. This SC model is a tie-rod design and is dimensionally shorter than an ISO 15552 cylinder; it is not a drop-in interchange for profile cylinders. Only the large bore SC125-SC250 models are classified as ISO 6430 class.
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 SC250X350TC FAQ
At 0.7 MPa operating pressure, the SC250X350TC generates a push force of 34361 N. The theoretical maximum force at 1.0 MPa is 5006 kgf (approx. 49059 N), but the rated maximum operating pressure is 0.9 MPa, yielding 44178 N.
No, the SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. For large bores (125-250 mm), the SC series conforms to the ISO 6430 class, which is a different standard. Always verify the body length (A=294 mm for 250 bore) and mounting dimensions against your machine.
