The AirTAC Airtac SGC Standard Cylinder SGC125X500S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 500mm 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 ISO 15552 tie-rod cylinder handles large-bore automation with a 500 mm stroke. 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. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG position switches. The standard TPU elastomer seals operate from -20 to +70 C, though a Viton H option extends this to 150 C. Air enters via the G1/2 port, and adjustable 40 mm cushions at both ends absorb kinetic energy near stroke end.

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.
Pushes heavy wood or steel pallets onto secondary packaging lines using its 6136 N thrust at 0.5 MPa.
Raises 300 kg tote bins along a 500 mm stroke, relying on external guides to prevent rod bending.
Ejects formed metal parts from hydraulic presses, using adjustable 40 mm cushions to stop smoothly.
When sizing, verify if the smaller bore is needed or if stepping up is required; note that 125 mm is the smallest SGC bore, while the next size up, 160 mm, offers 10053 N push at 0.5 MPa. For vertical loads, remember that a plain cylinder drifts when air is lost or the valve is centered, so an external rod lock or pilot-operated check valve is required to hold position. The air cushion only decelerates the piston near stroke end and never acts as a brake.
At 500 mm of travel, side-load and rod-bending stresses increase significantly, making an external guide essential to prevent premature seal wear. This model's built-in magnet pairs with CMSG, DMSG, or EMSG switches for end-of-stroke confirmation.
Quick checklist
This 125 mm bore cylinder features a G1/2 air port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum 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 tie-rod build adds rigidity, and the included -S magnet supports CMSG, DMSG, and EMSG sensors.
