About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X850CA
The AirTAC SC200X850CA is a robust double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa (28274 N at the 0.9 MPa maximum operating pressure). Its 40 mm diameter piston rod and 33 mm adjustable air cushion provide reliable deceleration for heavy payloads in the 850 mm stroke.
This configuration features a rear single clevis (CA) mount, part F-SC200CA, allowing the cylinder body to pivot during operation. The standard PT ports (PT3/4) and TPU seals suit general industrial environments with a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X850CA Is Used
Heavy Agricultural Machinery
Actuating large chutes, gates, or conveyors on harvesters and processing equipment where a pivoting, high-force cylinder is needed to move bulk material.
Industrial Press Actuation
Providing the main ram force for a medium-tonnage hydraulic-style press replacement using pneumatics, where the rear clevis mount simplifies integration into the press frame.
Wastewater Valve Control
Operating large quarter-turn or gate valves in water treatment plants, using the clevis mount to accommodate the valve's arc motion with 28 kN of pneumatic force.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X850CA the Right Cylinder?
For applications needing more force, the SC250 bore offers 24544 N at 0.5 MPa. If a smaller footprint is required, the SC160 bore provides 10053 N at the same pressure. At 850 mm stroke, the 40 mm rod is well-supported within the 1500 mm maximum standard stroke for this bore, but any significant side load should be managed with an external guide system to prevent rod bending and premature bearing wear. When replacing, match bore, stroke, PT port thread, CA mounting, and the non-magnet configuration exactly.
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 SC200X850CA FAQ
At the standard 0.5 MPa operating pressure, the cylinder pushes with 15708 N and pulls with 15080 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N.
No. The SC series is a tie-rod cylinder and is shorter than a comparable ISO 15552 profile cylinder, so mounting dimensions are not interchangeable. It directly replaces another AirTAC SC200 cylinder with the same stroke, PT ports, and CA clevis mount.
