About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X750
The AirTAC SC250X750 is a large-bore double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With a 50 mm diameter piston rod and a 750 mm stroke, this ISO 6430 class cylinder is built for heavy industrial linear motion where substantial force and a long working travel are required.
This model features a 294 mm body length (A dimension) and a 40 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly. The standard PT1" port and M42x2 rod thread ensure robust pneumatic connections. Operating on 40 µm filtered air, it functions reliably from -20 to +70 °C with its default TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X750 Is Used
Heavy-Gauge Pressing
Provides the 24544 N (0.5 MPa) force needed for forming, stamping, or laminating large metal or composite panels in durable goods manufacturing.
Palletizer Lift
The 750 mm stroke and high force capacity are ideal for elevating heavy, fully loaded pallets in automated material-handling and end-of-line packaging systems.
Industrial Compactor
Drives the compaction plate in large waste or recycling balers, utilizing the full 44178 N of force at 0.9 MPa to maximize material density.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X750 the Right Cylinder?
For applications requiring marginally less force, the SC200 bore provides 15708 N at 0.5 MPa, while stepping up is not an option within this family. The 750 mm stroke is within the 1500 mm maximum standard stroke for bore 250, ensuring standard availability. When replacing, match the 250 mm bore, 750 mm stroke, PT1" port thread, basic mounting configuration, and confirm the magnet requirement.
For this 750 mm stroke, carefully evaluate side-load conditions. A long, unsupported 50 mm rod can be subject to bending moments under even moderate lateral forces. To ensure bearing life and prevent rod damage, use an external linear guide or a guided cylinder configuration for any off-axis loading.
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 SC250X750 FAQ
At the standard 0.5 MPa operating pressure, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. As a standard double-acting pneumatic cylinder, the SC250X750 will drift or drop if air pressure is lost, exhausted, or the control valve is centered. The adjustable air cushions only decelerate the piston at the end of stroke and do not act as a lock. A pilot-operated check valve or external mechanical brake is required to safely hold a position.
