About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X40S
The SC200X40S is a large-bore double-acting tie-rod cylinder delivering a substantial 15708 N of push force at just 0.5 MPa, rising to 28274 N at the maximum operating pressure of 0.9 MPa. With a 40 mm stroke and a robust 40 mm diameter piston rod, it is built for short, powerful clamping, pressing, or ejecting operations in heavy industrial settings.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG sensors to be mounted directly on the tie-rod barrel for reliable, non-contact position sensing. The body length A is 244 mm, and the adjustable pneumatic cushion (33 mm length) decelerates the high-inertia load smoothly at the end of stroke.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X40S Is Used
Heavy-Duty Press Frames
Generates up to 28274 N of force at 0.9 MPa for short-stroke pressing, staking, or bearing insertion in assembly cells, with sensor confirmation of ram position.
Industrial Clamping Systems
The 40 mm rod and 15708 N force at 0.5 MPa provide rigid, high-force clamping for large weldments or machining fixtures, with magnetic sensors verifying clamp engagement.
Material Ejection & Diverting
Short 40 mm stroke is ideal for ejecting heavy parts from conveyor lines or diverting pallets, where the built-in magnet enables end-of-stroke detection in dusty environments.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X40S the Right Cylinder?
For applications needing even higher force, the SC250 bore provides 24544 N at 0.5 MPa. If a smaller footprint is acceptable and force requirements are lower, the SC160 bore offers 10053 N at the same pressure. This SC200X40S is a basic mount model; mounting accessories like the F-SC200LB foot mount or F-SC200TC centre trunnion must be ordered separately if required.
To ensure a correct replacement, match five key points: the 200 mm bore, 40 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the tie-rod body style. This cylinder 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 SC200X40S 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, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200X40S is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop under load. For load holding without live pressure, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve.
