Airtac SGC Standard Cylinder SGC125X370
The AirTAC Airtac SGC Standard Cylinder SGC125X370 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 370mm 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 SGC125X370
Delivering 6136 N of push force at 0.5 MPa, this large-bore tie-rod actuator handles heavy automation tasks. It uses the standardized ISO 15552 mounting interface, dropping directly into existing large-bore fixtures and saving engineering time. 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. Operating speed ranges from 30-500 mm/s.
Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. For real-world sizing, plan for about 3682 N of actual work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. The bore dictates a G1/2 air port and an M27x2.0 rod thread. Standard TPU seals handle -20 to +70 C, with Viton H available for 0-150 C environments.

Woodworking Clamps
Secures heavy timber assemblies during cutting or routing operations on industrial CNC routers.
Is the Airtac SGC Standard Cylinder SGC125X370 the Right Cylinder?
When sizing this 125 mm bore option, compare it against its neighbors: the larger 160 mm bore provides 10053 N push at 0.5 MPa, while there is no smaller SGC bore below 125. This 370 mm stroke falls well under the 1500 mm maximum, keeping the rod compact. For strokes of 500 mm or more, external guides are recommended to prevent rod bending under side loads. Since this model has no -S suffix, adding magnetic sensing requires switching to the SGC125X370-S variant. Remember that air cushions only decelerate the piston near stroke end; they do not function as a lock. If the application requires holding a load vertically during air loss, 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 SGC125X370 FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. It delivers 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.
No, this specific SKU lacks the internal magnet. You must select the -S variant to use CMSG, DMSG, or EMSG switches. It is dimensionally interchangeable per the ISO 15552 mounting interface, utilizing four steel tie rods for structural rigidity.
