About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400
The SC200X400 is a robust tie-rod cylinder delivering a substantial 15708 N of push force at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore and a 40 mm diameter piston rod, it is built for heavy-duty linear tasks, featuring a 400 mm stroke that fits well within the 1500 mm maximum standard stroke for this bore size.
This double-acting cylinder uses filtered air to power both the extend and retract strokes, with an adjustable air cushion at each end to decelerate the piston smoothly over a 33 mm distance. The body length A is 244 mm, and the standard port connection is PT3/4. This basic configuration comes with TPU seals for a standard operating temperature range of -20 to +70 C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400 Is Used
Heavy Pallet Lifting
Provides the high force needed for lifting and transferring heavy pallets in automated warehouses, using its 15708 N push force at standard line pressure.
Large Clamping Fixtures
Ideal for actuating large-scale welding or assembly jigs where a powerful, consistent clamping force of over 28000 N at 0.9 MPa is required.
Industrial Press Feed
Drives heavy-duty material feeding mechanisms in stamping presses, leveraging the robust 40 mm piston rod and adjustable cushioning to manage inertial loads.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400 the Right Cylinder?
When sizing, if the force requirement is lower, consider stepping down to the 160 mm bore SC160 series, which provides 10053 N of push force at 0.5 MPa. For a 400 mm stroke, ensure the rod is adequately supported against side loads; an external guide or a guided cylinder is strongly recommended to prevent rod bending and premature bearing wear.
For a direct replacement, match five critical specifications: the 200 mm bore, 400 mm stroke, PT3/4 port thread, the basic mounting style (no integrated bracket), and the absence of a built-in magnet. This model is a non-ISO 15552 tie-rod cylinder and is dimensionally interchangeable only with another AirTAC SC200 tie-rod cylinder of 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 SC200X400 FAQ
At the standard operating pressure of 0.5 MPa, 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 increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The SC200X400 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of its stroke to reduce impact; it is not a locking or holding brake. For load holding, an external rod lock or a pilot-operated check valve is required.
