About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50
The SC200X50 is a double-acting 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 a short 50 mm stroke, it provides a compact yet extremely powerful linear punch for pressing, clamping, and heavy lifting tasks. The 40 mm diameter piston rod and 33 mm adjustable air cushion at each end ensure robust alignment and smooth end-of-stroke deceleration.
This cylinder uses a PT3/4 port and an M36x2 rod thread, with a body length A of 244 mm. The standard TPU seals give an operating temperature range of -20 to +70 °C. As a genuine AirTAC SC series unit, it is built for high-force industrial automation where a shorter, non-ISO 15552 tie-rod design saves space.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50 Is Used
Heavy-Duty Press Frames
Generates up to 28274 N at 0.9 MPa for shop presses, bearing insertion, and forming dies where a short, high-force stroke is needed.
Pallet Lifting & Locking
Delivers 15708 N at 0.5 MPa to raise and lower heavy pallet stacks or lock lift tables in material handling stations.
Clamping & Fixturing
Provides powerful, controlled clamping force for large weld fixtures and machining centers, holding heavy workpieces securely during processing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50 the Right Cylinder?
Step up from the SC160 (push force 10053 N at 0.5 MPa) to this SC200 when you need roughly 50% more force for the same pressure. The 50 mm stroke is well within the 1500 mm maximum standard stroke for bore 200, making this a standard catalog item. When replacing, match five points: 200 mm bore, 50 mm stroke, PT3/4 port thread, basic mounting (no bracket), and no magnet. The SC is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 cylinder, so it is not a drop-in replacement for ISO 15552 profiles.
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 SC200X50 FAQ
At 0.5 MPa, push force is 15708 N and pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, push force reaches 28274 N. The theoretical maximum 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 (body length A is 244 mm for the SC200). It is not dimensionally interchangeable with ISO 15552 cylinders. It directly replaces another AirTAC SC200 tie-rod cylinder with matching stroke, port, and mounting.
