About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X140S
The SC250X140S is a double-acting tie-rod cylinder with a 250 mm bore and 140 mm stroke, equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. This model generates a substantial push force of 24544 N at 0.5 MPa and reaches 44178 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy-duty linear actuation.
With a 50 mm diameter piston rod and M42x2 knuckle thread, the cylinder provides robust mechanical connection. The 40 mm adjustable air cushion at each end decelerates the high-inertia load smoothly, protecting the end caps during rapid cycling. This genuine AirTAC SC unit uses standard PT ports and TPU seals for reliable operation from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X140S Is Used
Heavy Material Handling
Ideal for lifting and transferring large steel plates or heavy castings in a foundry, where the 24544 N push force at 0.5 MPa easily manages multi-ton loads.
Large Press Tool Actuation
Provides the high clamping force needed for a 5000 kgf industrial press, with the magnet allowing end-of-stroke confirmation via DMSG sensors.
Dam Gate Control
Operates a water control gate requiring sustained 44178 N of thrust at 0.9 MPa, with the adjustable cushion absorbing shock during closure.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X140S the Right Cylinder?
For applications requiring a slightly lower force profile, consider stepping down to the 200 mm bore SC series model, which provides 15708 N of push force at 0.5 MPa. When replacing an existing cylinder, ensure a full 5-point match: verify the 250 mm bore, 140 mm stroke, PT port thread, the basic mounting configuration, and the presence of the -S magnet option for sensor compatibility. The SC250 series is an ISO 6430 class 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 SC250X140S FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 24544 N of push force and 23562 N of pull force. At the maximum 0.9 MPa, the push force increases to 44178 N.
Yes, the -S suffix in SC250X140S designates a built-in magnet, allowing AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for contactless position sensing.
