About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X60
The SC250X60 is a large-bore double-acting cylinder delivering a substantial push force of 24544 N at 0.5 MPa, rising to 44178 N at the maximum operating pressure of 0.9 MPa. With a 60 mm stroke, this model is built for short, high-force clamping, pressing, or lifting applications where space is constrained but power cannot be compromised. The 50 mm diameter piston rod and 40 mm adjustable air cushion provide robust, controlled end-of-stroke deceleration.
This is a genuine AirTAC SC series tie-rod cylinder, featuring a 294 mm body length and PT1 inch port threads. Its ISO 6430 class design ensures reliable performance in heavy-duty industrial environments. The standard TPU seals offer an operating temperature range of -20 to +70 °C, making it suitable for general-purpose pneumatic systems requiring extreme force in a compact stroke.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X60 Is Used
Heavy-Duty Clamping
The 24544 N force at 0.5 MPa makes this cylinder ideal for welding jigs and assembly fixtures that must hold large workpieces rigidly in place during machining or fabrication.
Short-Stroke Pressing
Delivers up to 44178 N of push force at 0.9 MPa for pressing bearings, bushings, or forming light-gauge metal. The 60 mm stroke provides the precise, limited travel needed for press-fit operations.
Material Lifting & Ejection
Use this cylinder for ejecting heavy parts from molds or lifting and tilting heavy bins. The robust 50 mm rod and tie-rod construction withstand the shock loads common in foundry and heavy manufacturing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X60 the Right Cylinder?
Select the SC250 when your application demands forces in the 24 kN range at standard shop air pressure. For a step down in force, the SC200 bore provides 15708 N push at 0.5 MPa in a lighter package. For a step up, the SC250 is the largest standard SC bore, so consult AirTAC for custom larger solutions. When replacing an existing cylinder, ensure an exact 5-point match: 250 mm bore, 60 mm stroke, PT1 inch port thread, basic (no bracket) mounting, and no magnet. This tie-rod design is shorter than an ISO 15552 cylinder 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 SC250X60 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 at 1.0 MPa is 5006 kgf.
No. The SC250X60 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston can drift or the load can drop. For load-holding safety, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve to the circuit.
