About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1100
The AirTAC SC200X1100 is a double-acting tie-rod cylinder delivering substantial push force of 15708 N at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. With a 200 mm bore and a 40 mm diameter piston rod, this actuator is built for heavy industrial linear motion tasks requiring a long 1100 mm stroke.
This model features a body length A of 244 mm, resulting in a total extended length of approximately 1344 mm. It uses adjustable pneumatic cushioning (33 mm cushion length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The standard PT3/4 port threads and TPU seals provide reliable operation in normal temperature environments from -20 to +70 C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1100 Is Used
Sawmill Log Handling
Positions and clamps large-diameter logs on carriages and infeeds, using the 1100 mm stroke to traverse wide conveyor gaps with high force.
Marine Hatch Actuation
Opens and closes heavy deck hatches or ballast doors, where the 28274 N push force at 0.9 MPa overcomes static friction and salt-air corrosion demands a robust tie-rod design.
Hydraulic Press Substitute
Drives a 200-ton class press tool for light forming or compaction work in clean environments, leveraging the 15708 N force at standard shop air to replace a small hydraulic power unit.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1100 the Right Cylinder?
For applications needing slightly less force, the 160 mm bore SC160 series provides 10053 N push at 0.5 MPa, while the 250 mm bore SC250 steps up to 24544 N. At this 1100 mm stroke, ensure the rod is protected from side loading; an external guide or linear rail is strongly recommended to prevent rod bending and premature bearing wear. When replacing this cylinder, match five key points: 200 mm bore, 1100 mm stroke, PT3/4 port thread, basic mounting (no accessory bracket), and no magnet. This SC model is a tie-rod cylinder 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 SC200X1100 FAQ
At 0.5 MPa air pressure, 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, for a 200 mm bore with an 1100 mm stroke, the 40 mm rod is susceptible to bending under side loads. You must use an external guide rail or rod support to ensure linear motion and protect the rod bearing, especially when the rod is fully extended.
