About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000
The AirTAC SC250X1000 is a robust double-acting tie-rod cylinder delivering substantial linear force for heavy industrial applications. With a 250 mm bore and a 50 mm diameter piston rod, this model generates a theoretical push force of 24544 N at 0.5 MPa, scaling up to 44178 N at the maximum operating pressure of 0.9 MPa.
This cylinder features a 1000 mm standard stroke, an adjustable pneumatic cushion (40 mm length) for end-of-stroke deceleration, and a PT1" port for air supply. The body length A is 294 mm, resulting in a total extended length of approximately 1294 mm. It operates within a -20 to +70 °C temperature range using standard TPU/NBR seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000 Is Used
Heavy-Duty Press Frames
Provides the high force (up to 44178 N) needed for hydraulic-press-style pneumatic operations in metal forming, compacting, or laminating workstations.
Large-Scale Material Handing
Actuates heavy gates, diverter chutes, or large hopper doors in mining, aggregate, or bulk grain handling facilities requiring a 1000 mm stroke.
Structuarl Test Rigs
Delivers repeatable, high-magnitude linear force for static and cyclic load testing of large civil engineering or automotive components.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000 the Right Cylinder?
Select the SC250 when your application requires force in the 24.5 kN class at 0.5 MPa. If your load is lighter, consider stepping down to the SC200 bore, which provides 15708 N push force at the same pressure, potentially reducing air consumption and physical footprint. For any stroke of 300 mm or more, especially with a 1000 mm extension, carefully evaluate side loads; an unsupported long stroke can impose bending moments on the rod bearing. Use an external guide or linear rail system to absorb lateral forces and prevent premature seal wear or rod damage.
To ensure a direct replacement, match five key specifications: bore (250 mm), stroke (1000 mm), port thread (PT1"), mounting accessory (basic, no bracket), and the presence or absence of a magnet (this model has none). The SC is a 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 SC250X1000 FAQ
At 0.5 MPa, the theoretical push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 44178 N. The absolute maximum theoretical force at 1.0 MPa is 5006 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. It will only directly replace another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and mounting configuration.
