The AirTAC Airtac SGC Standard Cylinder SGC125X70TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 70mm 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 actuator features a 125 mm bore and a 70 mm stroke. The 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 to maximize service life. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
Equipped with a G1/2 port and a 32 mm rod, it operates at speeds of 30-500 mm/s. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. This 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.
Uses the 6136 N push force at 0.5 MPa to eject formed metal parts from a stamping die within a 70 mm travel distance.
Deploys the TC trunnion mount to act as a robust pneumatic stop gate for heavy unit loads on a conveyor line.
Secures large workpieces inside machining centers where the 125 mm bore provides the necessary holding thrust.
When sizing this 125 mm bore option, verify if the 6136 N output at 0.5 MPa meets your motion requirements; if you need more power, stepping up to the 160 mm bore yields 10053 N under the same pressure. As the smallest bore in the SGC family, there is no smaller standard option below it. The TC trunnion mount supplied here is ideal for pivoting loads, but remember a plain cylinder drifts when air is lost or the valve is centered—the end cushions only decelerate the piston, so add an external rod lock or pilot-operated check valve if you must hold a suspended load.
Quick checklist
This 125 mm bore cylinder features a G1/2 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 increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, meaning it cannot accept CMSG, DMSG or EMSG switches. If you require position sensing, you must select the -S variant. The unit does feature a genuine ISO 15552 mounting interface for fixture interchangeability.
