About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200
The SC200X200 is a large-bore double-acting pneumatic cylinder delivering substantial push force of 15708 N at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm stroke and a robust 40 mm diameter piston rod, this tie-rod cylinder is built for heavy industrial linear actuation tasks.
This model features a body length A of 244 mm, resulting in a total extended length of approximately 444 mm. The 33 mm adjustable air cushion at each end decelerates the piston smoothly, protecting the end caps from impact damage during high-speed operation. Its PT3/4 port threads and M36x2 rod thread are standard for this bore size.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200 Is Used
Sawmill Log Handling
Provides the high force needed to clamp and position large logs on a carriage, withstanding the dusty, demanding environment of a sawmill.
Heavy Agricultural Implement Actuation
Controls the lift and tilt functions on large tractor-towed implements like deep rippers or heavy-duty mowers, using its 15708 N push force at 0.5 MPa.
Large Valve Actuation
Operates high-torque butterfly or gate valves in water treatment and irrigation mains, where the 28274 N max force ensures reliable opening and closing under pressure.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200 the Right Cylinder?
Select the SC200 when your application requires a push force in the 15708 N class at standard plant pressure. For a step down in force, the SC160 bore offers 10053 N push at 0.5 MPa in a more compact 239 mm body length. For strokes of 300 mm or longer on this bore, carefully evaluate side loads; the 40 mm rod has high column strength, but an external guide or guided cylinder is recommended to protect the rod bearing from bending moments.
To ensure a direct dimensional replacement, match five key points: bore (200 mm), stroke (200 mm), port thread type (PT), mounting accessory (basic, no bracket), and the presence of a magnet (none). This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile 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 SC200X200 FAQ
At the standard operating pressure of 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 increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. This is a standard double-acting cylinder that will drift or drop if air pressure is exhausted or the directional valve is centered. To hold a load or maintain a position without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
