About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X400
The AirTAC SC250X400 is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. Its 50 mm diameter piston rod and 40 mm adjustable air cushion make it suitable for demanding linear actuation tasks where controlled deceleration of large masses is critical.
With a 400 mm stroke and a body length A of 294 mm, this ISO 6430 class cylinder provides substantial reach for pressing, lifting, and positioning applications. The standard PT1" port and M42x2 rod thread ensure secure, high-flow pneumatic connections for consistent cycle rates.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X400 Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces needed in hydraulic-style pneumatic press tools, with the adjustable cushion protecting tooling from impact damage at the end of the 400 mm stroke.
Large-Scale Material Handling
Suitable for lifting and transferring heavy pallets or bulk materials in warehouses, where the 24544 N push force at 0.5 MPa can manage substantial vertical loads within a compact tie-rod design.
Industrial Bending & Forming
Used in metal and plastic forming machinery to apply consistent, high-force linear motion for bending or stamping operations, leveraging the cylinder's robust 50 mm rod and 40 mm cushion length.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X400 the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the SC200 bore, which provides 15708 N of push force at 0.5 MPa. When selecting a cylinder with a 400 mm stroke, always evaluate the potential for side loading on the 50 mm rod. For non-axial loads, an external guide or a guided cylinder is strongly recommended to prevent rod bending and premature seal wear.
To ensure a correct replacement, match these five key points: bore (250 mm), stroke (400 mm), port thread (PT1"), mounting accessory (basic, no bracket), and magnet option (none). This model is a direct fit only for another AirTAC SC250 tie-rod cylinder with identical specifications.
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 SC250X400 FAQ
At 0.7 MPa (7 bar) operating pressure, the theoretical push force is 34361 N. The maximum push force at the 0.9 MPa operating limit is 44178 N. For retraction (pull) force, the value is lower due to the rod area; at 0.5 MPa the pull force is 23562 N.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is an ISO 6430 class cylinder. It should only replace another AirTAC SC250 tie-rod cylinder with the same bore, stroke, and port configuration.
