The AirTAC Airtac SGC Standard Cylinder SGC125X500 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 large-bore cylinder is built around a genuine ISO 15552 mounting interface for seamless fixture integration. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed under heavy thrust, while a two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 port and M27x2.0 rod thread handle the 125 mm bore's air volume efficiently.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. For sizing, plan for about 3682 N of actual work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The standard TPU seal handles -20 to +70 C, though a Viton H option extends this to 0-150 C for hot environments.

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.
Ejects formed metal parts from a 150-ton stamping press, utilizing the 500 mm stroke to clear the die bed completely before the next cycle.
Pushes empty pallets into a high-speed packaging line, using the 6136 N push force at 0.5 MPa to overcome stack friction.
Actuates a 500 mm transfer arm to push raw timber logs onto a secondary processing conveyor in a sawmill.
When sizing this 125 mm bore, 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 your payload exceeds the 313 kg vertical lift guideline. At 500 mm of stroke, the 32 mm rod is highly susceptible to bending under side loads, so an external guide or rod-end support is mandatory to prevent premature seal failure. Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the end of travel and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
Quick checklist
The 125 mm bore provides 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. This model uses a G1/2 air port.
Yes, the tie-rod construction uses standardized ISO 15552 mounting dimensions, so it drops directly into existing large-bore foot, flange, or trunnion brackets. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches without replacing the cylinder.
