Airtac SGC Standard Cylinder SGC125X450
The AirTAC Airtac SGC Standard Cylinder SGC125X450 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 450mm 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 SGC125X450
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles substantial actuation across its 450 mm travel. Four steel tie rods clamp the aluminium barrel to the covers for high structural 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 Ø125 mm bore uses a G1/2 air port and an M27x2.0 rod thread. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches. Standard TPU seals support a -20 to +70 C operating range, though Viton H variants can extend this to 150 C for high-temperature environments.

Where the Airtac SGC Standard Cylinder SGC125X450 Is Used
Press Ejection
Ejects formed metal stampings from a 150-ton press bed, utilizing the 450 mm stroke to clear the die area completely before the next cycle.
Pallet Diversion
Actuates a heavy-duty pusher arm to redirect loaded pallets onto a secondary packaging line, relying on 6136 N of thrust at 0.5 MPa.
Lift Gate Actuation
Raises and lowers a horizontal materials handling gate, moving smoothly through the 450 mm travel thanks to the 40 mm adjustable air cushions.
Is the Airtac SGC Standard Cylinder SGC125X450 the Right Cylinder?
When sizing this 125 mm bore unit, verify if the 6136 N push at 0.5 MPa provides adequate thrust, or step up to the 160 mm bore generating 10053 N for heavier demands. As this is the smallest SGC bore, there is no smaller standard option within this series. For any 450 mm stroke, ensure external guide rails are fitted to prevent rod bending under side loads.
Remember that exhausting air or centring the valve will cause the piston to drift, as the air cushions only decelerate the stroke near the end caps rather than locking the load. To suspend a vertical weight safely, integrate an external rod lock or a pilot-operated check valve into the pneumatic 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 SGC125X450 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 force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop into existing large-bore fixtures using LB foot, FA flange, CA clevis, or TC trunnion attachments. The rigid tie-rod construction ensures the aluminium barrel remains securely clamped under high thrust.
