Airtac SGC Standard Cylinder SGC200X420
The AirTAC Airtac SGC Standard Cylinder SGC200X420 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 420mm stroke, G3/4 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGC Standard Cylinder SGC200X420
Delivering 15708 N of push force at 0.5 MPa, this large-bore actuator tackles heavy industrial automation. The SGC200X420 is a double-acting tie-rod cylinder built to the ISO 15552 mounting interface, dropping directly into existing large-bore fixtures. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while a two-way piston seal maintains an internal oil reservoir for long service life. A G3/4 port and M36x2.0 rod thread handle the required air volume.
For practical sizing, plan for about 9425 N of real work at 0.5 MPa, which safely lifts roughly 801 kg vertically with a 2:1 margin. The default TPU seal handles -20 to +70 C, with a Viton H option for 0-150 C environments. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC200X420 Is Used
Press Die Ejection
Ejects heavy stamped metal parts from large press dies using 15708 N of thrust at 0.5 MPa.
Pallet Stopper Gate
Acts as a robust 420 mm stroke stopper gate for heavy pallets on high-throughput packaging lines.
Injection Mold Clamping
Provides auxiliary clamping force for large injection molding tools requiring steady retraction.
Is the Airtac SGC Standard Cylinder SGC200X420 the Right Cylinder?
When sizing this 200 mm bore, compare it against its neighbors: a 160 mm bore yields 10053 N push at 0.5 MPa, while stepping up to 250 mm provides 24543 N. If your load must remain suspended during air loss or valve centering, note that a standard cylinder will drift; the adjustable air cushion only decelerates the piston near stroke end and does not act as a brake. Install an external rod lock or pilot-operated check valve for secure holding. Additionally, at 420 mm of stroke, guide the load externally to prevent rod bending and side-load damage.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
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; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGC Standard Cylinder SGC200X420 FAQ
The SGC200X420 delivers 15708 N push and 15079 N pull at 0.5 MPa, 21991 N push and 21110 N pull at 0.7 MPa, with a theoretical maximum of 3204 kgf at 1.0 MPa. It uses a G3/4 air port and features a 50 mm adjustable air cushion at both ends.
No, this specific SKU does not include a magnet. You must purchase the -S variant to use CMSG, DMSG, or EMSG magnetic switches. The unit is dimensionally interchangeable per the ISO 15552 mounting interface and uses a rigid four-tie-rod construction.
