The AirTAC Airtac SGC Standard Cylinder SGC250X375TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 375mm 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 24543 N of push force at 0.5 MPa, this double-acting large-bore actuator handles the most demanding heavy-industry tasks. The Ø250 mm bore operates on a G1 air port, features a 50 mm piston rod, and generates a theoretical maximum output of 5006 kgf at 1.0 MPa. Four steel tie rods clamp the aluminum barrel to the covers, ensuring high structural rigidity under extreme thrust, while a two-way piston seal maintains an internal oil reservoir for long service life. Because this is a Ø250 bore model, TPU seals are not available; instead, the front-cover packing and buffer gasket utilize NBR, with a Viton H option available for 0-150 C high-temperature environments.
Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom bracketry. Plan for about 14726 N of real work at 0.5 MPa, or roughly 1251 kg lifted vertically with a 2:1 safety margin. The 375 mm stroke is a non-standard increment that falls well within the 1500 mm maximum, and the adjustable 60 mm air cushions at both ends decelerate the massive payload smoothly. Note that this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic 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.
Provides the 24543 N force required to actuate heavy-duty stamping dies and hold large automotive body panels during forming operations.
Utilizes the 375 mm stroke to push fully loaded pallets onto outbound conveyor lines, relying on the TC trunnion mount to accommodate angular alignment.
Drives massive mold ejection plates in heavy plastics manufacturing, using the 60 mm adjustable air cushions to prevent shock at the stroke ends.
When sizing this 250 mm bore option, compare its 24543 N push force at 0.5 MPa against the neighboring 200 mm bore, which provides 15708 N. If the 200 mm class is insufficient, this 250 mm model is the largest in the SGC family and provides the maximum available thrust. The integrated TC trunnion mount allows pivot-action integration, but because the stroke is 375 mm, you must account for potential side loads and ensure external guide rails are used to prevent rod bending under heavy payloads.
Remember that a plain double-acting cylinder will drift if air pressure is lost or the control valve is centered; the end-of-stroke cushions only decelerate the piston and do not function as a mechanical brake. To suspend a load safely mid-stroke, install an external pilot-operated check valve or a dedicated rod lock.
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.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You must order an SGC250 variant with the -S suffix to enable magnetic sensing.
