The AirTAC Airtac SGC Standard Cylinder SGC250X80 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm stroke, G1 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 massive thrust for heavy industry, the AirTAC SGC250X80 is a double-acting tie-rod cylinder built to the ISO 15552 mounting interface. It pushes with 24543 N and pulls with 23562 N at 0.5 MPa, utilizing a 50 mm rod and a G1 air port. Four steel tie rods clamp the aluminum barrel to the covers, providing high rigidity under large-bore loads, while the two-way piston seal maintains an internal oil reservoir for long service life.
Because this is a Ø250 bore, TPU seals are not offered; instead, the front-cover packing and buffer gasket use NBR (with a Viton H option for 0-150 C high-temperature environments). For real-world sizing, plan for about 14726 N of actual work at 0.5 MPa, which equates to lifting roughly 1251 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 24544 N | 23562 N |
| 0.7 MPa | 34361 N | — |
| Max (@1.0 MPa) | 5006 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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.
Provides the 24543 N push force at 0.5 MPa needed to clamp heavy die-sets within large automotive stamping presses.
Secures heavy industrial molds during injection molding cycles, utilizing its rigid four-tie-rod construction to resist deflection.
Acts as a high-force stopper gate in automated palletizing lines, halting loads weighing up to 1251 kg with a 2:1 vertical margin.
When sizing this 80 mm stroke actuator, compare it against the adjacent SGC bores: the Ø200 delivers 15708 N push at 0.5 MPa, while the Ø250 is the largest available in this series at 24543 N. If your application requires position feedback, you must select the -S magnet variant, as this base SKU cannot host sensing switches. Furthermore, a standard cylinder drifts when air is lost or the valve is centered—the 60 mm adjustable air cushions only decelerate the piston near stroke end, so install an external rod lock or pilot-operated check valve if you need to hold a suspended load.
Quick checklist
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. At 0.7 MPa the push is 34360 N and the pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. This 250 mm bore cylinder uses a G1 air port and a 50 mm piston rod.
No, this specific SKU does not include the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG switches. You would need to order the -S variant for position sensing. It is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop into existing large-bore fixtures.
