Airtac SGC Standard Cylinder SGC125X650
The AirTAC Airtac SGC Standard Cylinder SGC125X650 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 650mm 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 SGC125X650
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles substantial workloads over its 650 mm travel. The four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed to withstand large-bore thrust. Its standardized ISO 15552 mounting interface means it drops directly into existing large-bore fixtures, and a two-way piston seal maintains an internal oil reservoir for long service life.
Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. For sizing tasks, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The bore dictates a G1/2 port and an M27x2.0 rod thread, while TPU seals handle standard -20 to +70 C environments.

Where the Airtac SGC Standard Cylinder SGC125X650 Is Used
Pallet Transfer Diversion
Pushes heavy wood or steel pallets sideways onto secondary packaging lines using its 6136 N push force at 0.5 MPa across the 650 mm travel distance.
Automated Warehousing Pusher
Acts as a diverter arm in high-bay storage systems, moving totes weighing up to 313 kg with a 2:1 vertical lift safety margin.
Press Ejection Mechanism
Ejects formed metal parts from large stamping presses, relying on the rigid tie-rod construction to absorb shock without flexing.
Is the Airtac SGC Standard Cylinder SGC125X650 the Right Cylinder?
When sizing this 125 mm bore, verify if the 6136 N push at 0.5 MPa is sufficient, or step up to the 160 mm bore which provides 10053 N. If you need less force, there is no smaller SGC bore available. Since this 650 mm stroke is quite long, you must use external guides to prevent rod bending and side-load damage.
This model has no magnet, so external reed or solid-state sensors will not function. Furthermore, exhausting the air or centering the valve will cause the piston to drift, as the adjustable 40 mm air cushions only decelerate the rod near stroke end rather than locking it. Use a pilot-operated check valve or external rod lock to hold a suspended load.
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 SGC125X650 FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder uses a G1/2 air port and features a 32 mm piston rod with an M27x2.0 thread.
No, this specific SKU does not include the -S magnet option, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for magnetic sensing. The cylinder is dimensionally interchangeable per the ISO 15552 mounting interface and uses four steel tie rods for structural rigidity.
