The AirTAC Airtac SGC Standard Cylinder SGC125X80SN 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, the AirTAC SGC125X80SN is a robust double-acting large-bore tie-rod cylinder built to ISO 15552 mounting interface dimensions. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for extended lifespan. Because this 125 mm bore SKU includes the -S suffix, it hosts a piston magnet ready for CMSG, DMSG, or EMSG position switches.
This specific configuration ships with NBR (N) seals instead of the standard TPU, making it highly suitable for specific fluid environments where standard seals might degrade. Plan for about 3682 N of real work at 0.5 MPa, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin. The unit features a G1/2 air port, an M27x2.0 rod thread, and 40 mm adjustable air cushions at both ends to smooth out stroke transitions.

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 6136 N push force required to knock heavy stamped parts out of a 125-ton mechanical press bed safely.
Actuates a heavy-duty lane deflector on a packaging line, using the NBR seals to withstand occasional wash-down environments.
Raises a 300 kg gravity roller conveyor section vertically, operating comfortably within the calculated 313 kg safe lift margin.
When sizing this 80 mm stroke unit, consider the neighboring SGC bores: dropping down is not an option as 125 mm is the smallest in the SGC family, but stepping up to the 160 mm bore yields 10053 N of push force at 0.5 MPa if your application demands more muscle. For securing loads during air loss or valve centering, remember this cylinder will drift; the end cushions only decelerate the piston and act as neither a brake nor a lock. You must integrate an external rod lock or a pilot-operated check valve for suspended load safety. Furthermore, the -S magnet allows seamless integration with CMSG, DMSG, or EMSG sensors for end-position confirmation.
Quick checklist
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 piston rod. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, the tie-rod construction matches ISO 15552 mounting interface dimensions, allowing you to use standard LB foot, FA flange, or TC trunnion brackets. The -S magnet enables direct mounting of CMSG, DMSG, or EMSG electronic switches along the barrel groove.
