The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X300 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 300mm 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.
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 provide identical push and pull output. The aluminium barrel is clamped by four steel tie rods for structural rigidity, and it carries a G1/2 air port. Because the rod passes through both covers, the pressure area remains symmetric, yielding equal force both ways and a stable, anti-twist load path.
This non-magnet SKU cannot host position sensors and relies on external detection. It provides a safe working load of roughly 3440 N, which translates to lifting about 292 kg vertically with a 2:1 safety factor. Standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this range up to 150 C for hot environments.

Double-rod: the rod passes through both covers, so output force is equal in both directions.

SGC-family variants: SGC (double acting), SGCD (double rod), SGCJ (adjustable stroke). Mounting: LB / FA / FB / CA / CB / CR / TC / FTC / TCM1 / TCM2. Seals: TPU (blank) / Viton H / NBR N.
Drives two opposing machining heads simultaneously from one piston, ensuring perfectly synchronized cutting cycles.
Operates a bi-directional diverting gate where the equal push and pull force prevents binding under asymmetric material loads.
Lifts heavy platens vertically without rotational drift, using the dual rods to maintain strict parallel alignment.
Sized between the smaller SGCD160 (9425 N at 0.5 MPa) and larger alternatives, this 125 mm bore sits at the low edge of the SGCD family. Choose a double-rod configuration when your mechanism demands anti-rotation guidance, symmetric load distribution, or twin tooling driven from a single piston. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. For this 300 mm stroke, external guide rails are recommended to absorb side loads and prevent binding. Note that this specific SKU lacks a magnet, so it cannot use CMSG, DMSG, or EMSG sensors; add the -S suffix for magnetic sensing.
Quick checklist
The double-rod design yields equal force both ways: 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum is 1169 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, the air cushion only decelerates the piston near stroke end; it does not lock the load. Use an external rod lock or pilot-operated check valve for holding. Additionally, this non-S SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG switches.
