About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X345
The SC200X345 is a large-bore double-acting pneumatic cylinder delivering substantial push force for heavy industrial automation. With a 200 mm bore and 345 mm stroke, it generates 15708 N extending force at 0.5 MPa, rising to 28274 N at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, clamping, and lifting heavy assemblies.
This tie-rod cylinder features a 40 mm diameter piston rod with M36x2 threads and PT3/4 ports. The 33 mm adjustable air cushion at each end decelerates the piston smoothly, protecting end caps and reducing noise. Its body length A is 244 mm, giving an extended length of approximately 589 mm. Operating temperature range is -20 to +70 °C with standard TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X345 Is Used
Heavy Press & Clamp Fixtures
Generates up to 28274 N at 0.9 MPa for hydraulic-press alternatives in assembly cells, riveting stations, and high-force clamping of large weldments.
Pallet & Container Handling
Pushes 15.7 kN at standard shop air to transfer heavy pallets, lift dumpsters, or actuate large diverters on roller conveyor systems.
Industrial Saw & Shear Actuation
Provides the sustained linear motion for log cut-off saws, metal shears, and heavy guillotine blades where consistent force through the 345 mm stroke is critical.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X345 the Right Cylinder?
For applications requiring slightly less force, the 160 mm bore SC160 series provides 10053 N push at 0.5 MPa, while the 250 mm bore SC250 steps up to 24544 N at the same pressure. Always verify that the mounting and rod support can handle the cylinder's full thrust.
At a 345 mm stroke, side-loading on the 40 mm rod should be evaluated. If the load is not guided externally, consider adding a linear guide or switching to a guided cylinder to prevent rod bending and premature bearing wear. For exact replacement, match bore, stroke, PT port thread, basic mounting, and the absence of a magnet.
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 SC200X345 FAQ
At 0.5 MPa it delivers 15708 N pushing and 15080 N pulling. At 0.7 MPa push force is 21991 N, and at the maximum operating pressure of 0.9 MPa it reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200X345 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is exhausted or the directional valve centers, the piston will drift. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
