The AirTAC Airtac SGC Standard Cylinder SGC125X650SLB is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 650mm 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, this double-acting ISO 15552 tie-rod cylinder handles large-bore automation tasks with ease. 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 long service life. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
The built-in -S piston magnet directly supports CMSG, DMSG, and EMSG position switches. Because the stroke runs 650 mm, providing external guide support prevents rod bending under side loads. This model uses a G1/2 port, an M27x2.0 rod thread, and a 40 mm adjustable air cushion at both ends to decelerate the payload smoothly.

Pushes heavy timber pallets sideways onto secondary processing lines using the 6136 N thrust at 0.5 MPa.
Raises 300 kg mezzanine safety gates through the 650 mm travel, relying on the -S magnet for top and bottom confirmation.
Clears formed metal blanks from a 125-ton stamping press, utilizing the 40 mm adjustable cushions to soften end impacts.
Sizing demands looking both ways: stepping down is not an option as 125 mm is the smallest SGC bore, while moving up to the 160 mm bore increases thrust to 10053 N at 0.5 MPa. The included LB foot mounting bracket matches the ISO 15552 interface, allowing easy integration with standard fixtures. For this 650 mm stroke, add an external linear guide to absorb lateral forces and protect the rod. Remember that standard air cushions only decelerate the piston near stroke end; they do not lock the load. If power drops, the piston drifts, so install an external rod lock or pilot-operated check valve for vertical holding.
Quick checklist
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. 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 of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so standard LB foot brackets and other ISO fixtures fit perfectly. The -S suffix means it has a built-in magnet ready for CMSG, DMSG, or EMSG reed and electronic switches.
