About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X420
The SC200X420 is a large-bore double-acting pneumatic cylinder producing a theoretical push force of 15708 N at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa. Its 40 mm diameter piston rod and 33 mm adjustable air cushion are designed to manage substantial inertial loads, making this 420 mm stroke unit a workhorse for heavy linear actuation.
This tie-rod cylinder has a body length A of 244 mm and uses PT1/2 ports. The standard TPU seals provide a reliable operating temperature range of -20 to +70 °C. As a genuine AirTAC SC series unit, it is built for demanding industrial tasks where high force and consistent cycling are required.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X420 Is Used
Heavy Machinery Actuation
Operates high-resistance levers and gates on construction or agricultural equipment, where the 15708 N push force at 0.5 MPa provides ample power for lifting and shifting.
Pallet Handling Systems
Drives heavy-duty pallet lifts and transfer stations in automated warehouses, reliably moving loads up to 1.6 tonnes with smooth, cushioned end-of-stroke deceleration.
Large Press Tool Ejection
Provides the high ejection force needed for large stamping dies or moulds, with the 33 mm cushion absorbing impact energy to protect tooling during high-speed cycles.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X420 the Right Cylinder?
For applications needing slightly less force, the 160 mm bore SC160 series offers 10053 N push at 0.5 MPa. The SC200X420's 40 mm rod handles significant column loads, but at this 420 mm stroke, any side loading must be managed with an external guide or linear rail to prevent rod bearing damage and ensure seal life. When replacing an existing cylinder, match five points exactly: 200 mm bore, 420 mm stroke, PT1/2 port thread, basic (no bracket) mounting, 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 SC200X420 FAQ
At 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, the push force reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The SC200X420 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift. You must add a pilot-operated check valve or an external mechanical rod lock if load holding is a safety requirement.
