About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X55
The SC200X55 is a double-acting pneumatic cylinder delivering a substantial 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa). With a 55 mm stroke and a 40 mm diameter piston rod, this model is built for short, high-force clamping, pressing, or lifting tasks in heavy industrial machinery.
This tie-rod cylinder features a 244 mm body length (A dimension) and PT3/4 ports. Its adjustable air cushion decelerates the piston smoothly at each end of the 55 mm travel, reducing impact and vibration. The standard TPU seals provide reliable operation from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X55 Is Used
Heavy-Duty Clamping
The 15708 N force at 0.5 MPa makes the SC200X55 ideal for powerful, short-stroke clamping fixtures on welding or assembly lines.
Die Cushioning & Pressing
Use this 200 mm bore cylinder for short-travel pressing, stamping, or die cushioning where a compact, high-force actuator is needed.
Material Lift & Positioning
Provides a robust 55 mm lift stroke for heavy pallets or components in material handling stations, with adjustable cushioning for smooth stops.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X55 the Right Cylinder?
For applications needing slightly less force, the 160 mm bore SC160 series offers 10053 N at 0.5 MPa. If your load demands more, the 250 mm bore SC250 provides 24544 N. Always match replacement cylinders on all five critical points: 200 mm bore, 55 mm stroke, PT3/4 port thread, basic (no bracket) mounting, and the absence of a magnet.
Even with a short 55 mm stroke, avoid side loading the 40 mm rod directly. For off-axis forces, use an external linear guide or a guided cylinder to protect the rod bearing and seals from premature wear.
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 SC200X55 FAQ
At 0.7 MPa (7 bar), the SC200X55 produces 21991 N of push force. The theoretical maximum force at 1.0 MPa is 3204 kgf. Its pull force at 0.5 MPa is 15080 N.
Yes, the SC200X55 basic model can be ordered with a TC centre trunnion mount. The mounting accessory code is F-SC200TC, which includes the TCM1 trunnion bracket. This allows the cylinder to pivot for swinging loads.
