About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50STC
The AirTAC SC200X50STC is a double-acting tie-rod cylinder delivering a substantial 15708 N push force at 0.5 MPa (28274 N at 0.9 MPa). Its 200 mm bore and 50 mm stroke make it a compact powerhouse for short, high-force linear movements, with a 40 mm diameter piston rod providing excellent rigidity.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC suffix) supplied with the TCM1 bracket for pivoting applications. The total body length is 244 mm, and the adjustable air cushion (33 mm) effectively decelerates the high inertial load at end-of-stroke.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50STC Is Used
Heavy Press Tool Actuation
Provides the high clamping force needed for short-stroke pressing, stamping, or riveting operations in metal fabrication cells.
Mould Core Pull
Delivers powerful, controlled linear motion for pulling cores or slides in large injection moulds, with sensor confirmation via the built-in magnet.
Pivoting Diverter Gate
The centre trunnion mount allows the cylinder to pivot, making it ideal for actuating heavy diverter gates on high-throughput conveyor systems.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50STC the Right Cylinder?
Choose the SC200 for applications requiring forces up to 28274 N at 0.9 MPa. If your force requirement is lower, stepping down to a 160 mm bore (10053 N at 0.5 MPa) may reduce cost and air consumption. For strokes longer than 300 mm, consider an external guide to manage the 40 mm rod's bending moment under side loads. When replacing, match bore, stroke, PT port thread, TC mount with TCM1 bracket, and the built-in magnet (-S) to ensure sensor compatibility.
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 SC200X50STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 15708 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
Yes. The -S suffix indicates a built-in magnet, allowing you to clamp compatible CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the cylinder barrel to detect piston position.
