Airtac SGC Standard Cylinder SGC125X50S
The AirTAC Airtac SGC Standard Cylinder SGC125X50S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 50mm 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 SGC125X50S
Delivering 6136 N of push force at 0.5 MPa, this double-acting 125 mm bore cylinder handles heavy automation tasks within a compact 50 mm stroke. Its four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed for large-bore thrust, while a 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 your existing pneumatic schematics.
Because it is dimensionally interchangeable per the ISO 15552 mounting interface, this model drops directly into standard large-bore fixtures and shares accessories with similar ISO 15552 units. The built-in piston magnet (-S) enables direct mounting of CMSG, DMSG, or EMSG switches for position sensing. 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 SGC125X50S Is Used
Stamping Press Ejection
Uses the 6136 N push force at 0.5 MPa to knock heavy stamped metal parts out of a die quickly within the 50 mm stroke.
Pallet Diverter Gate
Leverages the ISO 15552 mounting interface for easy installation on a conveyor frame to push heavy pallets onto a parallel sorting line.
Heavy Carton Indexing
Employs the built-in magnet and CMSG sensors to confirm positioning when indexing dense, heavy cardboard cartons into a strapping machine.
Is the Airtac SGC Standard Cylinder SGC125X50S the Right Cylinder?
When sizing this 125 mm bore unit, compare your actual load against the available thrust grades. If 6136 N at 0.5 MPa is excessive, step down to a smaller bore; if your application demands more power, the next size up in the series is the 160 mm bore, which provides 10053 N of push force at the same pressure. This 50 mm stroke SKU is highly compact, minimizing overall length for tight machine layouts.
The included -S magnet allows seamless fitment of CMSG, DMSG, or EMSG sensors without extra hardware. Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near stroke end rather than locking it. To suspend a load safely during an emergency stop, incorporate an external rod lock or a pilot-operated check valve into your circuit.
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 SGC125X50S FAQ
This 125 mm bore cylinder features a G1/2 air port. It generates 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 force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it fits standard large-bore foot, flange, and trunnion accessories. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly for position detection.
