The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X900 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 900mm 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.
Generating 5734 N of equal force in both directions at 0.5 MPa, this AirTAC SGCD125X900 double-rod cylinder uses a symmetric piston to push and pull with identical power. The twin-rod architecture creates a balanced load path that resists torsional twist, letting you drive two separate tools simultaneously or mount a sensor cam on the back end. It features a G1/2 port and a genuine ISO 15552 mounting interface for direct fixture interchangeability.
Four steel tie rods clamp the aluminum barrel securely to the covers, maintaining a durable two-way piston seal across the 900 mm stroke. This bore yields a safe working load of about 3440 N, which translates to lifting roughly 292 kg vertically with a 2:1 safety margin. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

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.
Uses the protruding rod at both ends to operate two separate forming tools simultaneously with identical 5734 N force.
The dual-rod symmetric load path prevents piston rotation during the 900 mm stroke for precise linear positioning.
Mounts a cam or linkage on the rear rod end to trigger external mechanical switches without front-side interference.
Sizing this model means looking both ways: the 125 mm bore offers 5734 N each way at 0.5 MPa, sitting at the low edge of the range below the 160 mm bore (9425 N) and above smaller alternatives. A double-rod design is the right call when your mechanism demands anti-rotation guidance, symmetric load distribution, or twin tooling. You can mount it via FA, LB, TC, FTC, TCM1, or TCM2 brackets. Because the stroke is 900 mm, you must use external guides to prevent rod bending and absorb side loads. Also, this non-magnetic version cannot host position sensors.
Quick checklist
Force is equal both ways at 5734 N at 0.5 MPa and 8028 N at 0.7 MPa, with a theoretical max of 1169 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and it uses a G1/2 port.
No. The adjustable air cushions only decelerate the piston near stroke end; they do not lock. For load holding on air loss, you must install an external rod lock or a pilot-operated check valve.
