Airtac SGC Standard Cylinder SGC125X650SN
The AirTAC Airtac SGC Standard Cylinder SGC125X650SN 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.

About the Airtac SGC Standard Cylinder SGC125X650SN
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder is built for heavy-duty automation. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
This specific SKU features a 650 mm stroke, a G1/2 port, and an M27x2.0 rod thread. It includes a piston magnet for CMSG, DMSG, or EMSG sensors, and uses NBR seals suitable for standard operating temperatures. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC125X650SN Is Used
Press Ejection Systems
Provides the 6136 N push force required to eject formed metal parts from heavy stamping presses, utilizing the 650 mm stroke to clear the die area completely.
Pallet Diverters
Handles the lateral shifting of loaded pallets on high-throughput packaging lines, where the NBR seals and tie-rod rigidity withstand repeated impact loads.
Vertical Lift Gates
Raises and lowers heavy material handling gates, relying on the CMSG sensor integration to confirm open and closed positions across the long 650 mm travel.
Is the Airtac SGC Standard Cylinder SGC125X650SN the Right Cylinder?
When sizing this 125 mm bore actuator, compare it against the larger 160 mm bore (which provides 10053 N push at 0.5 MPa) if your application exceeds the 125 mm capacity, as there is no smaller SGC option. This model uses NBR seals, but a Viton H option is available for 0-150 C high-temperature environments.
Because this unit features a 650 mm stroke, external rod-end support or a guide mechanism is recommended to prevent side-load bending under heavy thrust. Furthermore, the standard air cushion only decelerates the piston near the end of travel; it does not act as a brake. If the load must be held vertically when air is lost or the valve is centered, you must install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGC Standard Cylinder SGC125X650SN FAQ
The SGC125 bore provides a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, it delivers 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. The air port size is G1/2.
No, the adjustable air cushion at both ends only decelerates the piston near the stroke end and acts purely as an end-of-trift dampener. It does not function as a lock or brake. To prevent drift when air is lost or the valve is centered, you must use an external rod lock or a pilot-operated check valve.
