Airtac SGC Standard Cylinder SGC125X210S
The AirTAC Airtac SGC Standard Cylinder SGC125X210S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 210mm 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 SGC125X210S
Generating 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles heavy automation tasks with a 210 mm stroke. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity under large-bore loads, while the two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 air port and M27x2.0 rod thread streamline integration into existing pneumatic setups.
Because the -S suffix provides a built-in piston magnet, this model supports CMSG, DMSG, and EMSG position switches. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The default TPU seals operate from -20 to +70 C, with a Viton H option available for environments up to 150 C.

Where the Airtac SGC Standard Cylinder SGC125X210S Is Used
Press Tool Ejection
Provides the 6136 N push force needed to eject formed metal parts from heavy stamping dies over a 210 mm travel distance.
Pallet Stopper Gate
Acts as a robust pneumatic stop gate on heavy-duty roller conveyors, using its 313 kg vertical lift equivalent to handle pallet impacts.
Platen Lifting
Raises and lowers industrial molding platens, relying on the four steel tie rods to maintain structural rigidity under high thrust.
Is the Airtac SGC Standard Cylinder SGC125X210S the Right Cylinder?
When sizing this 125 mm bore unit, verify your actual load requirements against the 6136 N push rating at 0.5 MPa. If your application demands less force, a smaller bore might suffice, but as the entry point of the SGC large-bore range, stepping up to the 160 mm bore yields 10053 N of push force at the same pressure. For this 210 mm stroke, side loads are minimal, but any stroke over 500 mm would require external guide rails to prevent rod bending.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; the adjustable air cushions only decelerate the piston near the end of travel. To suspend a load safely during an outage, install an external rod lock or a pilot-operated check valve. The -S magnet on this SKU allows direct mounting of CMSG, DMSG, or EMSG sensors for end-position confirmation.
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 SGC125X210S FAQ
This 125 mm bore cylinder features a G1/2 air port and generates 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop into standard large-bore fixtures. The -S suffix means it has a built-in magnet ready for CMSG, DMSG, or EMSG switches.
