The AirTAC Airtac SGC Standard Cylinder SGC125X115 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 115mm 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 125 mm bore cylinder handles demanding automation tasks. It features a 115 mm stroke, a G1/2 air port, and a 32 mm carbon steel rod with an M27x2.0 thread. Four steel tie rods clamp the aluminum barrel to the covers, ensuring high rigidity under heavy thrust. The two-way piston seal retains an oil reservoir for continuous lubrication and extended service life.
Because it follows the standardized ISO 15552 mounting interface, this model drops directly into existing large-bore fixtures and shares common accessories. Plan for roughly 3682 N of real work at 0.5 MPa, which equates to lifting about 313 kg vertically with a 2:1 safety margin. The standard TPU seal operates from -20 to +70 C, while a Viton H option extends this to 150 C. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

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 bearings into heavy housings on automated machining lines, utilizing the 6136 N push force to seat components accurately.
Acts as a robust pneumatic stop in high-throughput logistics conveyors, holding back loaded pallets with its 125 mm bore.
Secures injection mold halves during low-pressure closing sequences, relying on the rigid tie-rod construction to prevent deflection.
This 125 mm bore is the smallest in the SGC family; if your application requires less force, you would need to look outside this series, while stepping up to the 160 mm bore increases the 0.5 MPa push force significantly to 10053 N. The 115 mm stroke provides ample travel for mid-range motions. Since this model has no -S suffix, it cannot support magnetic sensors. If your design requires position feedback, select the -S magnet variant. Furthermore, a standard double-acting cylinder drifts when air is lost or a valve is centered. The adjustable 40 mm air cushion only decelerates the piston near the end of stroke; to hold a load securely, install an external rod lock or a pilot-operated check valve.
Quick checklist
This 125 mm bore cylinder features a G1/2 air port and delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must choose the -S variant to use CMSG, DMSG, or EMSG magnetic switches. The unit is built with a standardized ISO 15552 mounting interface, allowing it to interchange with existing large-bore fixtures and accessories.
