About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1200
The SC200X1200 is a large-bore, double-acting pneumatic cylinder designed for heavy linear actuation. At 0.5 MPa operating pressure, it generates a substantial push force of 15708 N, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa.
This 200 mm bore model features a robust 40 mm diameter piston rod with an M36x2 knuckle thread and PT3/4 port connections. The tie-rod construction provides a serviceable design with a 33 mm adjustable air cushion at each end to decelerate high-inertia loads. The body length A is 244 mm, giving a total extended length of approximately 1444 mm for this 1200 mm stroke configuration.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1200 Is Used
Heavy Material Handling
Provides the high force needed for lifting, pushing, or transferring heavy pallets and structural components in industrial logistics systems.
Agricultural Machinery Actuation
Controls large gates, chutes, or hopper doors on harvesters and processing equipment, delivering reliable force in dusty, demanding environments.
Large Press Feed Systems
Powers the transfer of heavy steel sheets or plates into stamping presses, where the 28274 N maximum force at 0.9 MPa ensures positive material movement.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1200 the Right Cylinder?
For applications requiring less force, consider stepping down to the 160 mm bore, which provides 10053 N push force at 0.5 MPa. If your load demands exceed 15708 N at 0.5 MPa, the 250 mm bore model steps up to 24544 N. Always match the replacement cylinder on all five critical points: 200 mm bore, 1200 mm stroke, PT3/4 port thread, basic mounting (no bracket), and the absence of a built-in magnet.
With a 1200 mm stroke, the unsupported rod length is significant. Any side loading, even minor, can cause rod deflection, bearing wear, and premature seal failure. For this stroke length, it is strongly recommended to guide the load externally with a linear rail or rod guide, or to use an external guide unit to absorb transverse forces and protect the cylinder.
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 SC200X1200 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 21991 N and the pull force is 15080 N. The maximum allowable operating pressure is 1.0 MPa, yielding a theoretical push force of 31416 N.
No. The SC200X1200 is a standard double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. To hold a load or position without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
