Airtac SGCD Dual Rod Cylinder SGCD200X250
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD200X250 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 250mm 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 SGCD Dual Rod Cylinder SGCD200X250
Delivering 15079 N of thrust each way at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to provide perfectly symmetric output force. A rod exits both covers, meaning the effective area and resulting push or pull power are identical regardless of travel direction. This yields a safe working load of about 9047 N, or roughly 769 kg lifted vertically with a 2:1 margin. The G3/4 air port feeds the chamber efficiently, while four steel tie rods clamp the aluminum barrel securely.
Because the piston passes through both ends, the assembly resists torsional twist and guides the load symmetrically. The standard TPU seals handle temperatures from -20 to +70 C, with a Viton H option available for 0-150 C environments. Note this specific SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG switches without upgrading to the -S variant. The 50 mm adjustable air cushions at each end absorb kinetic energy, though an external rod lock is required to hold a load securely during air loss.

Where the Airtac SGCD Dual Rod Cylinder SGCD200X250 Is Used
Twin-Spindle Drilling
Drives two opposing machining heads simultaneously with equal 15079 N force, ensuring perfectly balanced feed rates on both sides of a heavy workpiece.
Symmetric Lift Platform
Lifts and lowers a 769 kg vertical load using both rod ends to maintain parallel alignment, preventing torsional binding without external linear guides.
Dual-End Transfer Pusher
Indexes parts forward on one side while retracting an empty pallet on the other, maximizing cycle efficiency through a symmetric load path.
Is the Airtac SGCD Dual Rod Cylinder SGCD200X250 the Right Cylinder?
Sizing this actuator requires comparing the equal-both-ways output against neighbouring bores. Stepping down to the 160 mm bore drops the 0.5 MPa force to 9425 N, while stepping up to the 250 mm bore raises it to 23562 N. The 200 mm bore sits comfortably in the middle for applications needing around 15 kN of symmetric thrust. Choose a double-rod configuration when the mechanism demands anti-rotation stability, needs to drive two tools simultaneously from one piston, or requires a sensor cam on the back end. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. For this 250 mm stroke, ensure external guide rails carry any heavy side loads to prevent premature seal wear. Remember that this non-magnetic version cannot host position sensors.
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 SGCD Dual Rod Cylinder SGCD200X250 FAQ
This 200 mm bore cylinder provides equal force in both directions: 15079 N at 0.5 MPa and 21110 N at 0.7 MPa. The theoretical maximum is 3075 kgf at 1.0 MPa. It features a G3/4 port, a 40 mm rod, M36x2.0 rod threads, and 50 mm adjustable cushions at both ends.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant to enable magnetic position sensing. The double-rod design still offers a back-end rod for mechanical cam actuation if needed.
