Airtac SGC Standard Cylinder SGC125X425S
The AirTAC Airtac SGC Standard Cylinder SGC125X425S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 425mm 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 SGC125X425S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore 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. 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 -S suffix adds a piston magnet for CMSG, DMSG, or EMSG position switches. It uses a G1/2 port, an M27x2.0 rod thread, and a 40 mm adjustable air cushion at both ends. Standard TPU seals handle temperatures from -20 to +70 C, with Viton H available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X425S Is Used
Press Ejection
Uses the 6136 N push at 0.5 MPa to eject formed metal parts from a hydraulic press bed safely.
Pallet Squaring
Deploys the 425 mm stroke to square heavy wooden pallets against a rigid stop before automated banding.
Log Diverter
Swings a heavy gate on a packaging line to divert bulk materials into secondary processing chutes.
Is the Airtac SGC Standard Cylinder SGC125X425S the Right Cylinder?
As the smallest bore in the SGC family, the 125 mm size provides a baseline 6136 N push at 0.5 MPa. If your application needs less force, you must step outside the SGC series, but stepping up to the 160 mm bore yields 10053 N for heavier demands. Because this 425 mm stroke is relatively long, ensure your guiding structure prevents rod bending and side loads.
The built-in magnet matches CMSG, DMSG, and EMSG sensors for end-position confirmation. Remember that standard air cushions only decelerate the piston near the stroke end; they do not lock the rod. If air pressure drops, the load will drift, so install an external rod lock or pilot-operated check valve for secure holding.
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 SGC125X425S FAQ
This 125 mm bore cylinder features a G1/2 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, dropping into the same large-bore fixtures. The tie-rod construction adds rigidity, and the -S magnet supports CMSG, DMSG, or EMSG switches.
