About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X250
The AirTAC SC250X250 is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa, rising to 44178 N at the maximum operating pressure of 0.9 MPa. With a 50 mm diameter piston rod and M42x2 male knuckle thread, it is built for high-force industrial automation tasks where robust construction is non-negotiable.
This 250 mm stroke model has a total extended body length of 544 mm, based on a 294 mm base dimension. The adjustable pneumatic cushion, set at 40 mm, decelerates the massive piston smoothly, protecting end caps from impact damage. Its PT1 port supplies ample flow for rapid cycling of the large volume bore.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X250 Is Used
Heavy Machinery Actuation
Powers blades, chutes, and hopper gates on agricultural and construction equipment, providing the immense force needed to move dense materials.
Hydraulic Press Alternatives
Replaces short-stroke hydraulic rams in clean environments, offering 5 tonnes of theoretical force with cleaner pneumatic operation and simpler control.
Mining Conveyor Tensioning
Maintains high tension on large-scale mining and quarry conveyor belts, absorbing shock loads with its robust 50 mm rod and tie-rod construction.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X250 the Right Cylinder?
Select the SC250 when your application demands force in the 24544-44178 N range. If your load is lighter, the SC200 bore provides 15708 N at 0.5 MPa, saving energy and physical space. For strokes of 300 mm or longer on this 50 mm rod, evaluate side-load conditions carefully; an external guide rail or guided cylinder is recommended to prevent rod bending and premature bearing wear under offset loads. Ensure a 5-point match for replacement: 250 mm bore, 250 mm stroke, PT port thread, basic mounting, and no magnet.
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 SC250X250 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, push force reaches 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
No. The SC series is a tie-rod cylinder that is shorter than an ISO 15552 profile cylinder. The SC250 is an ISO 6430 class round-body cylinder and is not dimensionally interchangeable with ISO 15552 types. It directly replaces another AirTAC SC250 of the same stroke and port configuration.
