The AirTAC Airtac SGC Standard Cylinder SGC125X75 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 75mm 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 serious thrust to short-stroke automation. The SGC125X75 is built on a genuine ISO 15552 mounting interface, dropping seamlessly into existing large-bore fixtures and accessory profiles. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed to handle sudden large-bore thrust without flexing.
Because this 75 mm stroke SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches. In practice, you should plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The bore dictates a G1/2 port, and the standard TPU seal operates from -20 to +70 C, while 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.
Uses the 6136 N push force at 0.5 MPa to knock heavy stamped metal parts out of a die quickly within the compact 75 mm stroke.
Actuates a heavy-duty deflector plate on a packaging line, relying on the rigid four-tie-rod construction to absorb repeated side-impacts.
Opens and closes heavy bulk-material discharge gates where the short 75 mm travel is sufficient to release granular materials.
When sizing this 125 mm bore, compare it against its neighbors: stepping down is not an option within the SGC series as this is the smallest bore, but stepping up to the 160 mm bore yields 10053 N of push at 0.5 MPa. Choose the 125 mm if 6136 N is sufficient, avoiding the bulk of the larger bores. Since this specific SKU has no -S magnet, you must select an external mechanical limit switch or proximity sensor if position detection is required.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near stroke end rather than locking it. For vertical or suspended loads that must hold position during an air failure, integrate an external pilot-operated check valve or a dedicated rod lock.
Quick checklist
The SGC125X75 delivers 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. The air port size is G1/2, determined by the 125 mm bore.
This specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches without upgrading to an -S variant. It is dimensionally interchangeable per the ISO 15552 mounting interface, supporting LB foot, FA/FB flange, CA/CB clevis, and TC trunnion styles.
