The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X75 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 75mm stroke, G1 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.
Generating 23562 N of equal force in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance heavy loads. The G1 air port feeds a bore that safely handles about 14137 N of real work, translating to a vertical lift capacity near 1201 kg with a 2:1 margin. Four steel tie rods clamp the aluminum barrel securely to the covers.
Because the rod passes through both covers, the pressure area stays identical each way, preventing torsional twist and enabling twin-tool drives. This 250 mm bore skips TPU seals entirely, relying on NBR packings with a Viton H option for 0-150 C heat. Note that this specific SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG sensors without switching to an -S variant.

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 forming tools simultaneously from opposite rod ends, ensuring perfectly synchronized press strokes without torsional twist.
Lifts heavy industrial platforms symmetrically, using the equal both-ways force to prevent sagging and maintain precise vertical alignment.
Pushes heavy pallets from either side of a transfer line, utilizing the symmetric load path to keep the diversion mechanism square.
As the largest standard bore, the 250 mm sits at the high edge of the SGCD range, stepping up from the 200 mm bore which provides 15079 N both ways at 0.5 MPa. Choose this double-rod configuration when your mechanism demands anti-rotation guidance, symmetric load paths, or a rear rod end to mount a sensor cam. Mounting hardware includes FA, LB, TC, FTC, TCM1, and TCM2 brackets. Even at this 75 mm stroke, you should support any side loads with external guide rails to prevent binding. Remember that a plain cylinder drifts on air loss; add an external rod lock or pilot-operated check valve if the load must hold position.
Quick checklist
This double-acting double-rod cylinder outputs 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. Because the rod exits both ends, this force is equal in both directions. The theoretical max is 4805 kgf at 1.0 MPa. It features a 50 mm rod, a G1 port, and a 60 mm adjustable cushion at each end.
No, this specific SKU does not have a magnet in the piston, so it cannot accept CMSG, DMSG, or EMSG sensors. You must select the -S variant of the SGCD250 to enable magnetic switching. The double-rod design still allows mechanical actuation or rear-rod cam sensing if needed.
