About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1100
The AirTAC SC250X1100 is a robust double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa, scaling up to a substantial 44178 N at the maximum operating pressure of 0.9 MPa. With an 1100 mm stroke and a 50 mm diameter piston rod, this model is engineered for heavy industrial linear tasks requiring significant force over a long travel distance. The total extended body length is approximately 1394 mm.
This cylinder features a 40 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly, protecting the end caps from impact damage. The SC250 bore is classified under ISO 6430 for larger bore tie-rod cylinders. It uses a PT1" port and an M42x2 rod thread, operating on standard filtered air within a -20 to +70 °C temperature range with its default TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1100 Is Used
Log Sawmills & Forestry
Provides the high force and long stroke needed to drive log splitters, veneer lathes, and heavy timber positioning arms in sawmill operations.
Heavy Agricultural Machinery
Actuates large grain chute diverters, fertilizer spreader gates, and heavy-duty baling press rams on agricultural equipment requiring robust, reliable linear motion.
Scrap Metal Compaction
Powers the main ram in large scrap metal balers and car crushers, where the 44178 N force at 0.9 MPa compacts dense materials into transportable blocks.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1100 the Right Cylinder?
Select the SC250X1100 for applications demanding the highest force output in the SC family, where its 24544 N at 0.5 MPa is necessary. If your load requires less force, stepping down to the SC200 bore reduces the push force to 15708 N at the same pressure, potentially lowering air consumption and cost. For any stroke exceeding 300 mm, carefully assess side loading; an unsupported 1100 mm stroke with a 50 mm rod is susceptible to bending under lateral forces, and an external guide or a guided cylinder configuration is strongly recommended to protect the rod bearings and seals.
To ensure a direct replacement, verify five key specifications against your existing unit: the 250 mm bore, the 1100 mm stroke, the PT1" port thread, the basic (no accessory) mounting configuration, and the absence of a built-in magnet. This model is a tie-rod design and is dimensionally shorter than an ISO 15552 cylinder, so it is not a drop-in replacement for that profile.
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 SC250X1100 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, the push force reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The SC250X1100 is a standard double-acting cylinder and will not hold position if air pressure is lost or the directional valve is centered. The piston will drift. To safely hold a load or maintain a position without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve.
