The AirTAC Airtac SGC Standard Cylinder SGC250X250S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 250mm 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, this double-acting ISO 15552 tie-rod cylinder uses a 250 mm bore and a 250 mm stroke to generate 24543 N of push force at 0.5 MPa. Four steel tie rods clamp the aluminium barrel to the covers for extreme rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. Plan for about 14726 N of real work at 0.5 MPa, which means it lifts roughly 1251 kg vertically with a 2:1 safety margin.
Because this SKU includes the -S magnet, it directly supports CMSG, DMSG and EMSG position switches. The 250 mm bore uses a G1 air port, an M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends. Note that TPU seals are not offered at this bore size; the front-cover packing and buffer gasket are NBR, with a Viton H high-temperature option available for 0 to 150 C 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.
Provides the 24543 N push at 0.5 MPa needed to form thick steel plates in automated mechanical press lines.
Uses the 250 mm bore and 250 mm stroke to positively strip and eject heavy wooden pallets from magazine stacks.
Shifts heavy injection molds along production tracks, relying on the rigid four-tie-rod build to handle the mass.
When sizing this 250 mm bore unit, the next step down is the 200 mm bore delivering 15708 N push at 0.5 MPa, while the 250 mm bore itself is the largest in the SGC family with no larger standard option. If your application drops below 15000 N, stepping down to the 200 mm bore saves air volume and physical footprint. For position feedback, the -S magnet on this model pairs perfectly with CMSG, DMSG or EMSG sensors.
Remember that the standard adjustable air cushion only decelerates the piston near the end of stroke; it does not lock or hold the load. If air pressure is lost or the valve is centered, the rod will drift, so you must add an external rod lock or a pilot-operated check valve for suspended loads. With a 250 mm stroke, the side-load leverage is moderate, but always ensure your mounting—whether LB foot, TC trunnion or a U knuckle—supports the rod against bending.
Quick checklist
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. It delivers 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum force of 5006 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops into the same large-bore fixtures and accessories. The included -S magnet enables CMSG, DMSG and EMSG switches, and the rigid tie-rod construction handles high thrust without flexing.
