About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100TC
The AirTAC SC250X100TC is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at just 0.5 MPa, rising to 44178 N at the maximum operating pressure of 0.9 MPa. With a 100 mm stroke and a 50 mm diameter piston rod, this ISO 6430 class cylinder provides robust linear thrust for large-scale industrial automation tasks.
This specific model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC250TC), allowing the cylinder to pivot and absorb angular misalignment in swinging load applications. The adjustable air cushion (40 mm length) decelerates the piston smoothly at end-of-stroke, protecting the end caps from impact damage. Standard PT ports and TPU seals with a -20 to +70 °C operating range complete the configuration.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100TC Is Used
Heavy Press & Forming
Generates up to 4.5 tonnes of force at 0.9 MPa for stamping, bending, or compression forming operations where a compact 100 mm stroke is sufficient.
Foundry & Mill Equipment
Operates gate valves, dampers, and heavy material diverters in harsh environments. The pivoting trunnion mount handles structural misalignment.
Large Part Clamping
Secures massive workpieces on welding or machining fixtures. The adjustable cushion prevents impact shock that could disturb the part position.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100TC the Right Cylinder?
Select the SC250 when your application requires extreme push forces above 20000 N at standard plant air pressure. If your load is lighter, stepping down to the SC200 bore reduces push force to 15708 N at 0.5 MPa, which may lower system cost and air consumption. For side-loaded or long-stroke applications, always use an external guide or linear bearing to protect the 50 mm rod from bending stress.
To ensure a direct drop-in replacement, match five key points: the 250 mm bore, 100 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the absence of a built-in magnet. This cylinder is dimensionally a tie-rod type, not an ISO 15552 profile, so it is not interchangeable with extruded-body cylinders.
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 SC250X100TC FAQ
At 0.5 MPa, 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 reaches 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
No. The SC250X100TC is a double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end. For load holding, you must add an external rod brake or a pilot-operated check valve.
