About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X70TC
The SC250X70TC is a large-bore double-acting tie-rod cylinder delivering substantial force in a compact 70 mm stroke. At 0.5 MPa air pressure it generates 24544 N pushing and 23562 N pulling, rising to a formidable 44178 N push at the maximum operating pressure of 0.9 MPa.
This model is factory-configured with a TC centre trunnion mount (supplied with the TCM1 bracket, part code F-SC250TC), allowing the cylinder body to pivot as it strokes—ideal for swinging or articulating loads. The 50 mm diameter piston rod features an M42x2 male knuckle thread, and the adjustable air cushion (40 mm length) decelerates the high-inertia piston smoothly at end-of-travel.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X70TC Is Used
Heavy Gauge Forming
Applies over 24 kN of force at moderate line pressure to form thick sheet metal or composite panels, with the trunnion mount allowing the tooling to follow an arc.
Pivoting Transfer Stations
The TC centre trunnion enables the cylinder to swing a heavy transfer arm or turntable through a precise 70 mm stroke arc on a production line.
Industrial Compaction
Delivers high force in a short stroke for compacting waste, biomass, or recyclable materials into dense bales or briquettes within a baler frame.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X70TC the Right Cylinder?
For heavy-duty clamping or pressing where this 250 mm bore is over-specified, stepping down to a 200 mm bore reduces push force to 15708 N at 0.5 MPa, saving energy and physical space. If even greater force is required, confirm larger bore availability from the datasheet. The 70 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: 250 mm bore, 70 mm stroke, PT port thread, TC centre trunnion mounting, and the absence of a magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders; it is shorter in overall length.
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 SC250X70TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The SC250X70TC is a double-acting pneumatic cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
