About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X35
The AirTAC SC200X35 is a robust double-acting tie-rod cylinder built for high-force applications in a compact 35 mm stroke. With a 200 mm bore, it generates a substantial 15708 N of push force at just 0.5 MPa, making it ideal for pressing, clamping, and heavy lifting tasks where space is limited.
This model features a 40 mm diameter piston rod, PT3/4 port threads, and a 33 mm adjustable air cushion to decelerate the high-inertia load smoothly. The body length (A) is 244 mm, and the total extended length is approximately 279 mm. As a genuine AirTAC SC series cylinder, it offers reliable performance in demanding industrial environments.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X35 Is Used
Heavy-Duty Pressing
The 15708 N force at 0.5 MPa makes this short-stroke cylinder perfect for powerful pressing, stamping, or riveting operations where the work is done in a small, controlled linear movement.
Material Clamping
Ideal for securely clamping large workpieces or molds in CNC machines and assembly jigs. The 35 mm stroke provides rapid lock/unlock action with immense holding force.
Industrial Lifting
Use this cylinder for short-lift scissor tables or heavy-component ejection systems. Its high force output easily handles multi-ton loads within a compact 279 mm extended length.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X35 the Right Cylinder?
Select the SC200X35 when your application requires the force of a 200 mm bore but only a very short working stroke. If you need even more force, consider stepping up to the SC250 series, which provides 24544 N of push force at 0.5 MPa. For a lighter, more compact solution, the SC160 bore delivers 10053 N at the same pressure.
To ensure a correct replacement, match five key points: bore (200 mm), stroke (35 mm), port thread (PT3/4), mounting style (basic), and the presence of a magnet (none on this model). This cylinder is a direct replacement for another AirTAC SC200X35 tie-rod unit with the same configuration.
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 SC200X35 FAQ
At the standard 0.5 MPa operating 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. The SC series 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 or the load will drop. For load-holding safety, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
