About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X90
The AirTAC SC200X90 is a heavy-duty tie-rod cylinder delivering 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. With a 200 mm bore and 90 mm stroke, it is built for applications requiring immense force in a compact linear distance, such as heavy pressing, clamping, or lifting.
This double-acting cylinder features a 40 mm diameter piston rod, PT3/4 ports, and a 33 mm adjustable air cushion to decelerate high-inertia loads smoothly. The body length A is 244 mm, making the total extended length approximately 334 mm. It operates on filtered air from 0.15 to 1.0 MPa within a standard temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X90 Is Used
Heavy Pressing & Stamping
Generates over 28 kN of force at 0.9 MPa, ideal for hydraulic-replacement pressing, stamping, and die-casting ejection where high force density in a pneumatic package is required.
Large Clamping Fixtures
Provides stable, high-force clamping for large weldments, machining fixtures, or injection mold locking, ensuring workpieces remain immobile during processing.
Material Compaction
Used in waste compactors, balers, and recycling machinery to deliver the substantial linear thrust needed to compress bulk materials into dense, manageable forms.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X90 the Right Cylinder?
For applications needing slightly less force, the SC160 bore provides 10053 N at 0.5 MPa, while the SC250 bore steps up to 24544 N. Always match the replacement cylinder on all five critical points: 200 mm bore, 90 mm stroke, PT3/4 port thread, basic mounting (no bracket), and the absence of a magnet. The SC200 is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
At this stroke length, the 40 mm rod is well-supported within the cylinder, but any external side load must be managed with an external guide or linear rail. Relying solely on the rod bearing to absorb lateral forces will cause premature wear and seal failure.
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 SC200X90 FAQ
At 0.5 MPa, the push force is 15708 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 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. It is a direct replacement only for another AirTAC SC200 tie-rod cylinder with matching bore, stroke, PT3/4 port, and basic mounting.
