About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160
The SC250X160 is a high-force double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial 24544 N push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With a 250 mm bore and a 160 mm stroke, this model uses a robust 50 mm diameter piston rod with an M42x2 male thread and a PT1 inch port for high flow rates.
This ISO 6430 class cylinder features an adjustable pneumatic cushion at both ends, with a 40 mm cushion length to decelerate heavy loads smoothly. The body length A is 294 mm, making the total extended length approximately 454 mm. It operates on filtered air within a standard temperature range of -20 to +70 °C, using durable TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160 Is Used
Heavy Sawmill & Forestry Equipment
Provides the high force needed for log positioning, clamping, and splitting operations in rugged sawmill environments. The 50 mm rod withstands significant side loads when externally guided.
Large Agricultural Machinery
Controls heavy implements and gates on harvesters or large-scale planting equipment, delivering reliable 24544 N push force from standard tractor or central hydraulic/pneumatic systems.
Industrial Press & Forming
Ideal for compacting, pressing, and heavy-duty clamping fixtures in manufacturing. The adjustable 40 mm cushion ensures smooth deceleration of the high-inertia press platen.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160 the Right Cylinder?
This 250 mm bore cylinder is suited for applications requiring forces in the 24544 N class at standard plant pressure. If your load requires less force, stepping down to a 200 mm bore (15708 N at 0.5 MPa) can reduce air consumption and physical footprint. For strokes of 300 mm or more, always evaluate side-loading on the 50 mm rod; an external guide or a guided cylinder is recommended to prevent rod bearing damage and ensure linear motion integrity.
When replacing this cylinder, ensure a 5-point match: 250 mm bore, 160 mm stroke, PT1 inch port thread, basic mounting (no included brackets), and no built-in magnet. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC250X160 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 increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. As a standard double-acting cylinder, it will not hold position or support a load if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke end and is not a locking or holding brake. For load holding, you must add an external rod lock or a pilot-operated check valve.
