About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650
The SC250X650 is a heavy-duty double-acting tie-rod cylinder delivering a substantial 24544 N of push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). With a 50 mm diameter piston rod and a 294 mm body length, this 250 mm bore actuator is built for large-scale industrial automation tasks requiring high force over a mid-range 650 mm stroke.
This model features a 40 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly, protecting the end caps and reducing noise. The standard PT1" port threads supply ample flow for the large bore volume, while the TPU seals ensure reliable operation within a -20 to +70 °C temperature range.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650 Is Used
Heavy Gauge Pressing
The 24544 N push force at 0.5 MPa makes the SC250X650 ideal for hydraulic-press alternatives in forming, stamping, or laminating operations where a 650 mm stroke is needed to load and unload large workpieces.
Pallet & Container Handling
Deploy this cylinder for lifting, tilting, or transferring heavy pallets and bulk containers in logistics centers. Its 50 mm rod and robust tie-rod construction handle the high cycle counts and off-axis loads common in material handling.
Structural Test Rigs
Use the SC250X650 in civil or mechanical test frames to apply controlled, high-force cyclical loads to beams, joints, or components. The adjustable cushioning protects both the test article and the cylinder during high-speed dynamic testing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650 the Right Cylinder?
Select the SC250 when your application demands forces in the 24.5 kN class at standard plant pressure. For a step down in force, the SC200 bore generates 15708 N at 0.5 MPa, offering a more compact and lighter alternative if the load allows. Always confirm that the 50 mm rod is adequately supported against side loads, especially at the full 650 mm extension; an external guide or a guided cylinder is strongly recommended to prevent rod bearing damage and seal wear from bending moments.
For a direct replacement, match five key points: the 250 mm bore, the 650 mm stroke, the PT1" port thread, the basic (no accessory) mounting configuration, and the absence of a built-in magnet. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC250X650 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 34361 N and the pull force on the retract stroke is 23562 N. The maximum push force at the 0.9 MPa limit is 44178 N.
Not directly. This specific model code does not include the '-S' magnet option, so the piston does not have a magnetic ring. To use CMSG or DMSG sensors, you would need to order the SC250X650-S variant, which includes a built-in magnet for sensor mounting on the tie-rod barrel.
