Airtac SGCD Dual Rod Cylinder SGCD125X500
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X500 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 500mm stroke, G1/2 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 SGCD125X500
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to equalize output force. That symmetric pull-side area translates to a safe working load of roughly 3440 N, or about 292 kg lifted vertically with a 2:1 safety margin. The G1/2 port feeds the 125 mm bore at speeds of 30-500 mm/s.
Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures. This non-magnetic SKU lacks the -S option and cannot host CMSG or DMSG sensors. Note that the 40 mm adjustable air cushions only decelerate the piston near stroke end; they do not hold the load on air loss, so fit an external rod lock or pilot-operated check valve for suspended loads.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X500 Is Used
Dual-Station Conveyor Transfer
Drives two synchronized pusher arms from opposite rod ends to index pallets on a conveyor belt without twisting.
Symmetric Machining Clamp
Clamps a heavy workpiece from both sides simultaneously, ensuring a balanced load path during milling operations.
Guided Vertical Press
Uses the equal both-ways force for a 500 mm lowering press stroke, relying on external guides to prevent rod deflection.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X500 the Right Cylinder?
This 125 mm bore sits at the low edge of the SGCD range, offering 5734 N equal force both ways at 0.5 MPa. If your application needs less power, there is no smaller SGCD bore, but stepping up to the 160 mm bore yields 9425 N both ways. Choose a double-rod configuration when you need anti-rotation guidance, twin tooling driven from both ends, a symmetric load path, or a rear-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a 500 mm stroke, you must provide external guide support to prevent rod bending and manage side loads over the extended length. Remember this specific SKU has no magnet and cannot accept 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 SGCD125X500 FAQ
Because it is a double-rod cylinder, force is equal both ways using the rod-side area. It outputs 5734 N at 0.5 MPa and 8028 N at 0.7 MPa, with a theoretical max of 1169 kgf at 1.0 MPa. It features a G1/2 port, 40 mm adjustable cushions, and operates at 30-500 mm/s.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG sensors. You must order the -S variant to enable magnetic switching. Also, remember the air cushions only decelerate the piston; use an external rod lock or pilot-operated check valve if you need to hold a load vertically.
