Airtac SGC Standard Cylinder SGC125X30S
The AirTAC Airtac SGC Standard Cylinder SGC125X30S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 30mm 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 SGC125X30S
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder handles heavy-duty actuation within a very compact 30 mm stroke. Four steel tie rods clamp the aluminium barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 port and M27x2.0 rod thread streamline integration into existing pneumatic setups.
Built to the ISO 15552 mounting interface, it drops directly into standard large-bore fixtures and uses compatible accessories. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position switches. 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 SGC125X30S Is Used
Short-Stroke Pressing
Applies 6136 N of force at 0.5 MPa to seat bearings or stamp small components in automated assembly lines.
Heavy Part Ejection
Uses the 30 mm stroke to rapidly push finished metal castings off a conveyor without occupying excessive machine length.
Pallet Stopper Gate
Acts as a high-force physical stop to halt heavy pallets at a packaging station, utilizing the ISO 15552 mounting interface for rigid fixture attachment.
Is the Airtac SGC Standard Cylinder SGC125X30S the Right Cylinder?
When sizing this 125 mm bore actuator, verify if the 6136 N push at 0.5 MPa provides adequate thrust; stepping up to the 160 mm bore yields 10053 N, while no smaller SGC bore exists below 125 mm. The 30 mm stroke is ideal for short clamping or ejecting motions without requiring side-load guides. Since this SKU features the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation. Remember that a standard cylinder drifts when air is lost or the valve is centered, so add an external rod lock or pilot-operated check valve if the application requires strict load 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 SGC125X30S 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, with a theoretical maximum of 1251 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the stroke end and does not act as a brake. The piston will drift if air is lost or the valve is centered, so an external rod lock or pilot-operated check valve is required for load holding.
