The AirTAC Airtac SGC Standard Cylinder SGC250X215S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 215mm 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 SGC250X215S is a double-acting ISO 15552 tie-rod cylinder built around a 250 mm bore. It generates 24543 N of push force and 23562 N of pull force at 0.5 MPa, scaling up to a theoretical maximum of 5006 kgf at 1.0 MPa. Four steel tie rods clamp the aluminum barrel to the covers for exceptional rigidity under high loads, while the two-way piston seal maintains an internal oil reservoir for long service life. Because this is a 250 mm 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-temp environments).
The 215 mm stroke operates at 30-500 mm/s, and the included -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for position detection. A G1 air port handles the large volume flow required for this bore size. For practical sizing, plan for about 14726 N of real work at 0.5 MPa, which equates to lifting roughly 1251 kg vertically with a 2:1 safety margin. The adjustable 60 mm air cushions at both ends absorb end-of-stroke impact, but remember they only decelerate the piston; they do not lock the rod in place.

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 actuate heavy-duty stamping press clamps and feed heavy gauge steel coils.
Lifts automotive engine pallets weighing up to 1251 kg vertically using a 2:1 safety margin, guided by external rails to prevent rod side-loading.
Shifts substantial injection molding tooling bases, utilizing the 60 mm adjustable air cushions to decelerate the heavy 250 mm piston smoothly at stroke ends.
When sizing this 250 mm bore model, note that it is the largest in the SGC family, so there is no larger standard bore to step up to if your application exceeds its 24543 N push at 0.5 MPa. If your load is lighter, stepping down to the 200 mm bore reduces the push force to 15708 N at 0.5 MPa, which saves air volume and physical footprint. The 215 mm stroke falls well under the 1500 mm maximum, so standard rod-bending concerns are minimal, but always ensure the load is guided to prevent side loads on the M42x2.0 threaded rod. Because this SKU includes the -S magnet, it is fully compatible with CMSG, DMSG, and EMSG switches. If the machine loses air pressure or the valve is centered, the piston will drift; to maintain a vertical load safely, integrate an external rod lock or a pilot-operated check valve rather than relying on the cushions.
Quick checklist
The SGC250X215S delivers 24543 N push and 23562 N pull at 0.5 MPa, and 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 air port, a 50 mm piston rod, and an M42x2.0 rod thread.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into standard large-bore ISO 15552 fixtures and mounting accessories like TC trunnions or CA clevis. Additionally, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG electronic or reed switches directly to the cylinder barrel.
