The AirTAC Airtac SGC Standard Cylinder SGC125X90S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 90mm 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 brings genuine ISO 15552 mounting-interface interchangeability to heavy fixtures. Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity, while a two-way piston seal maintains an internal oil reservoir for long service life. Because this SKU includes the -S magnet, it is ready for CMSG, DMSG or EMSG position switches.
With a 125 mm bore, 90 mm stroke and a G1/2 port, plan for about 3682 N of real work at 0.5 MPa, which lifts roughly 313 kg vertically with a 2:1 safety margin. The adjustable 40 mm air cushions at both ends absorb kinetic energy near the stroke limits, and the TPU seal handles temperatures from -20 to +70 C (a Viton H option extends this to 150 C).

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.
Supplies the 6136 N push at 0.5 MPa needed to eject formed metal parts from a 125-ton stamping press bed.
Raises a 90 mm diverter arm to reroute heavy industrial pallets on a high-speed packaging conveyor line.
Drives the main tilt mechanism on a vacuum lifting beam handling sheet steel, safely managing the 313 kg vertical lift margin.
As the smallest bore in the SGC family, the 125 mm size is the entry point for large-bore thrust; stepping up to the 160 mm bore raises push force to 10053 N at 0.5 MPa. If air pressure drops or the valve centres, the piston drifts because the standard cushion only decelerates the stroke end rather than locking the load—add an external rod lock or pilot-operated check valve for suspended loads. The built-in -S magnet pairs directly with CMSG, DMSG or EMSG sensors, and standard LB, FA or TC mounts fit the ISO 15552 interface.
Quick checklist
The SGC125X90S features a 125 mm bore and a G1/2 air port. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops into existing large-bore fixtures. Its four steel tie rods clamp the barrel to the covers, providing the high rigidity needed to handle large-bore thrust without flexing.
