About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1050
The AirTAC SC250X1050 is a large-bore double-acting tie-rod cylinder engineered for heavy industrial force requirements, delivering 24544 N of push force and 23562 N of pull force when operated at 0.5 MPa. With a 250 mm bore and a 1050 mm stroke, this model features a robust 50 mm diameter piston rod with an M42x2 knuckle thread, making it suitable for applications demanding both high thrust and structural rigidity.
Built to the ISO 6430 class standard for large-bore cylinders, the SC250X1050 includes a 40 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly, reducing end-of-stroke impact. The body length A is 294 mm, resulting in a total extended length of approximately 1344 mm. Operating on filtered air from 0.15 to 1.0 MPa, this cylinder uses standard TPU/NBR seals for a temperature range of -20 to +70 °C and connects via PT1" ports.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1050 Is Used
Heavy Press & Forming
Provides the high clamping and pressing forces required in large hydraulic-style pneumatic press replacements, stamping, and metal forming operations where 24544 N of push force is essential.
Bulk Material Handling
Operates large gates, diverters, and chutes in mining, aggregate, and agricultural bulk handling systems, using its long 1050 mm stroke and high force to move heavy material flows reliably.
Structural Testing Rigs
Applies controlled, repeatable linear force in civil and mechanical engineering test frames for load-testing beams, columns, and large structural components up to 44178 N at 0.9 MPa.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1050 the Right Cylinder?
For applications requiring slightly less force, the SC200 bore provides 15708 N of push force at 0.5 MPa in a more compact package, while the SC250 remains the top choice when maximum thrust within the SC family is needed. At a 1050 mm stroke, this cylinder operates well within the 1500 mm maximum standard stroke for the 250 mm bore, ensuring standard lead times.
When replacing this cylinder, match five key specifications: 250 mm bore, 1050 mm stroke, PT1" port thread, the specific mounting accessory (if any), and the magnet option (-S suffix for sensor compatibility). For strokes of this length, ensure the load is guided externally or use a guided cylinder configuration if significant side forces are present, as the long 50 mm rod can be subject to bending moments under lateral loads.
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 SC250X1050 FAQ
At 0.7 MPa operating pressure, the SC250X1050 generates 34361 N of push force on extension and 32987 N of pull force on retraction. The maximum theoretical force at 1.0 MPa is 5006 kgf (49058 N push).
No. The SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. The SC body length is shorter than an equivalent ISO 15552 unit, so dimensional interchangeability is not guaranteed. This model is an ISO 6430 class cylinder for large bores. Replace only with another AirTAC SC250 tie-rod cylinder matching the 1050 mm stroke, PT1" ports, and mounting configuration.
