The AirTAC Airtac SGC Standard Cylinder SGC125X125S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 125mm 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 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator brings serious thrust to demanding pneumatic setups. It features a 125 mm bore, a 125 mm stroke, and a G1/2 air port. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life.
Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. The included -S piston magnet enables CMSG, DMSG, and EMSG position switches. Plan for about 3682 N of real work at 0.5 MPa, which means it lifts roughly 313 kg vertically with a 2:1 safety 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.
Drives 313 kg vertical loads to seat heavy bearings into automotive housings using a 2:1 safety margin.
Applies 3682 N of working force to align heavy wooden pallets before automated stretch wrapping.
Actuates a heavy-duty routing gate on a high-speed logistics line, utilizing the 125 mm stroke.
When sizing this 125 mm bore unit, stepping down is not an option within the SGC family, but stepping up to the 160 mm bore yields 10053 N of push at 0.5 MPa if you need more power. Remember that a standard cylinder drifts when air is lost or a valve centers; the adjustable air cushion only decelerates the piston near stroke end, so add an external rod lock or pilot-operated check valve for held loads. The -S magnet matches perfectly with CMSG, DMSG, or EMSG sensors for position feedback.
Quick checklist
This model uses a G1/2 air port. It delivers 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 the same foot, flange, and trunnion fixtures. The tie-rod build adds rigidity, and the -S magnet supports CMSG, DMSG, and EMSG switches.
