The AirTAC Airtac SGC Standard Cylinder SGC125X30H is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 30mm 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 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder is built around the ISO 15552 mounting interface for direct fixture interchangeability. The SGC125X30H uses a robust tie-rod construction where four steel rods clamp the aluminum barrel to the covers, ensuring high rigidity under heavy thrust. It features a 125 mm bore, a 30 mm stroke, and a G1/2 air port.
This specific SKU includes the Viton H high-temperature seal option, extending the operating range from -20 to +70 C up to 0-150 C for hot environments. Because this model lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.

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.
Short 30 mm stroke provides rapid, high-force ejection of forged parts from heated dies, with the Viton H seal surviving ambient shop temperatures up to 150 C.
Clamps injection moulding tooling components securely using 6136 N of thrust at 0.5 MPa, maintaining integrity in high-heat production zones.
Applies compact 30 mm high-force pressing strokes for sealing heavy industrial packaging materials near heat-shrink tunnels.
When sizing this 125 mm bore actuator, compare it against the larger 160 mm option, which provides 10053 N of push force at 0.5 MPa if your application demands more power. Since 125 mm is the smallest bore in the SGC series, there is no smaller standard model to step down to. This 30 mm short-stroke unit operates at 30-500 mm/s and uses an M27x2.0 rod thread. Note that a standard SGC cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the stroke ends. For suspended loads, integrate an external rod lock or a pilot-operated check valve. To add position sensing, you must select the -S magnet variant instead of this SKU.
Quick checklist
The SGC125X30H has a 125 mm bore and a G1/2 air port. It generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. It includes the Viton H seal, raising the operating temperature range to 0-150 C. The four steel tie rods clamp the assembly to ISO 15552 mounting interface dimensions for easy fixture integration.
