About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X280FA
The SC250X280FA is a large-bore double-acting pneumatic cylinder delivering a substantial push force of 24544 N at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With a 280 mm stroke and a robust 50 mm diameter piston rod, this ISO 6430 class cylinder is built for heavy industrial linear motion tasks.
This model features a front rectangular flange (FA) for secure panel mounting, with the accessory part coded F-SC250FA. The body length A is 294 mm, and the adjustable pneumatic cushion at each end is 40 mm, effectively decelerating high-inertia loads. It uses a PT1 inch port and standard TPU seals for an operating temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X280FA Is Used
Heavy Timber Processing
Provides the high force needed to drive log splitters, veneer presses, and sawmill carriage feeds, where the 24544 N push at 0.5 MPa easily handles dense hardwood.
Large Agricultural Machinery
Controls heavy-duty functions on harvesters and tillage equipment, such as lifting and positioning large toolbars, with the robust 50 mm rod resisting bending in the field.
Scrap Metal Baling
Powers the main compression ram in recycling balers, compacting scrap metal or high-volume cardboard with up to 44178 N of force at 0.9 MPa for maximum bale density.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X280FA the Right Cylinder?
Select the SC250 bore for applications requiring a push force between roughly 24500 N and 44000 N. If your force requirement is lower, stepping down to an SC200 bore reduces the push force to 15708 N at 0.5 MPa. For strokes of 300 mm or greater, carefully assess side loads; the 50 mm rod is strong, but an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
To ensure a direct replacement, match five key specifications: the 250 mm bore, the 280 mm stroke, the PT1 inch port thread, the FA front flange mounting, and the absence of a built-in magnet on this model.
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 SC250X280FA 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, the AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than a standard ISO 15552 profile cylinder, so it is not a direct drop-in replacement. It is designed to replace another AirTAC SC tie-rod cylinder with the same 250mm bore, 280mm stroke, PT1" port, and FA front flange mount.
