The AirTAC Airtac SGC Standard Cylinder SGC125X80 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 80mm 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 large-bore pneumatic actuator is built around a genuine ISO 15552 mounting interface for direct fixture and accessory interchangeability. The four steel tie rods clamp the aluminum barrel to the front and rear covers, providing high structural rigidity under heavy thrust, while a heterogeneous two-way piston seal maintains an internal oil reservoir for long service life. Operating at 30-500 mm/s, it features a 32 mm carbon steel rod, an M27x2.0 rod-end thread, and a G1/2 air port.
Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing. For practical sizing, plan for about 3682 N of real work at 0.5 MPa (60 percent of the rated push), which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, though Viton H options extend this range to 150 C for high-thermal 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.
Drives small bushings and bearings into automotive transmission housings using its 313 kg vertical lift capacity.
Actuates heavy-duty lane diverters on packaging lines, relying on the rigid tie-rod build to absorb high side-shock.
Secures large wood panels during CNC routing, utilizing the 6136 N push force to prevent workpiece shifting.
When sizing this 125 mm bore unit, verify if the 6136 N push at 0.5 MPa provides adequate thrust, or if stepping up to the 160 mm bore (10053 N) is necessary for heavier loads; as the smallest SGC bore, there is no smaller standard option below it. The 80 mm stroke is well within standard limits and avoids the side-load and rod-bending risks associated with extended strokes over 500 mm, though standard guide rules still apply. Remember that a plain double-acting cylinder drifts when air is lost or a valve is centered, as the adjustable air cushion only decelerates the piston near stroke end rather than locking it, so incorporate an external rod lock or pilot-operated check valve if your application requires strict position holding.
Quick checklist
The SGC125X80 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. This model uses a G1/2 air port fixed by the 125 mm bore.
No, this specific SKU does not include a magnet. You must choose the -S variant (SGC125X80-S) to use CMSG, DMSG, or EMSG magnetic switches. The standard ISO 15552 mounting interface remains identical, but this base model cannot support magnetic position sensing.
