About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X115
The AirTAC SC250X115 is a large-bore double-acting tie-rod cylinder built for high-force industrial applications. With a 250 mm bore operating at 0.5 MPa, it generates 24544 N of push force, rising to 44178 N at the maximum 0.9 MPa operating pressure. The 115 mm stroke is well within the 1500 mm maximum standard range for this bore.
This model features a 50 mm diameter piston rod with an M42x2 knuckle thread and a PT1 inch port. The adjustable pneumatic cushion (40 mm length) decelerates the piston smoothly at stroke end. The body length A is 294 mm, giving a total extended length of approximately 409 mm. ISO 6430 class dimensional characteristics apply to this 250 mm bore cylinder.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X115 Is Used
Heavy Press Tool Actuation
Provides the 44 kN max force needed for clamping, punching, or forming tools in metal fabrication cells, running on standard 0.9 MPa shop air.
Large Damper & Gate Drive
Operates heavy ventilation dampers or bulk material slide gates in cement and mining plants, where the 24544 N push at 0.5 MPa overcomes high static friction.
Industrial Compactor Ram
Drives the compaction plate in waste or recycling balers, using the full 115 mm stroke to compress material into dense, manageable bales.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X115 the Right Cylinder?
Select the SC250 when your application demands forces in the 24-44 kN range. If 24544 N at 0.5 MPa exceeds your requirement, consider stepping down to the SC200 bore, which provides 15708 N push force at the same pressure. For strokes of 300 mm or longer on this 50 mm rod, evaluate side-load conditions carefully—an external linear guide or guided cylinder is recommended to prevent rod bearing damage from bending moments.
For direct replacement, match five key points: bore (250 mm), stroke (115 mm), port thread (PT1 inch), mounting style (basic, no accessory bracket), and magnet option (none). This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile cylinder and is not 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 SC250X115 FAQ
At 0.5 MPa air pressure, the push force is 24544 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. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552. Match it directly with another AirTAC SC250 tie-rod cylinder of the same bore, stroke, and port thread.
