About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1200
The AirTAC SC250X1200 is a robust double-acting tie-rod cylinder delivering substantial linear force for heavy industrial applications. With a 250 mm bore and 1200 mm stroke, it generates a push force of 24544 N at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, lifting, and positioning large assemblies.
This model features a 50 mm diameter piston rod with an M42x2 thread and a 40 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly. The body length (A) is 294 mm, resulting in a total extended length of approximately 1494 mm. It is equipped with standard PT1" ports and TPU seals for operation in temperatures from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1200 Is Used
Heavy Pressing & Forming
Applies 24.5 kN of consistent force at 0.5 MPa for stamping, bending, or laminating large panels in woodworking and metal fabrication.
Large-Scale Material Handling
Powers long-stroke pushers and lift tables in warehouses, moving pallets or heavy rolls of material with a controlled, cushioned motion.
Structural Testing Rigs
Provides the high-force actuation needed for load-testing structural components, beams, or geotechnical samples in civil engineering labs.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1200 the Right Cylinder?
Select the SC250X1200 when your application demands force in the 24 kN range at standard plant pressure. If a slightly lower force is acceptable, stepping down to a 200 mm bore reduces push force to 15708 N at 0.5 MPa, potentially saving space and air consumption. For strokes of 1200 mm, carefully evaluate side-load conditions; a rod this long under compressive load is susceptible to bending. Use an external guide rail or rod-alignment coupler to prevent rod-bearing damage and ensure seal longevity. When replacing an existing cylinder, match five critical points: 250 mm bore, 1200 mm stroke, PT1" port thread, basic mounting configuration, 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 SC250X1200 FAQ
At 0.5 MPa, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, push force reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
A 1200 mm stroke with a 50 mm rod is vulnerable to bending under side load. Always install an external linear guide or a rod-alignment coupler to absorb transverse forces. The cylinder's internal rod bearing is designed for axial thrust, not radial loads.
