About the Airtac SGC Standard Cylinder SGC125X100TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious thrust to demanding setups. The SGC125X100TC features a robust tie-rod construction where four steel rods clamp the aluminum barrel to the covers, ensuring high rigidity under heavy loads. Its two-way piston seal maintains an internal oil reservoir for long service life. Because it adheres to the ISO 15552 mounting interface, it drops seamlessly into existing large-bore fixtures.
This specific SKU features a TC trunnion mount and uses a G1/2 air port. Without the -S suffix, it lacks a piston magnet and cannot host CMSG, DMSG, or EMSG sensors. For practical sizing, 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.

Where the Airtac SGC Standard Cylinder SGC125X100TC Is Used
Press Ejection
Provides the robust 6136 N push force needed to eject formed metal parts from heavy stamping presses.
Pallet Diversion
Uses the TC trunnion mount to pivot a heavy diverter arm, redirecting large pallets on high-throughput packaging lines.
Lift Gate Actuation
Raises and lowers industrial loading dock gates where the 313 kg vertical lift capacity handles heavy steel panels safely.
Is the Airtac SGC Standard Cylinder SGC125X100TC the Right Cylinder?
When sizing this 125 mm bore, stepping down is not an option within the SGC family as it is the smallest available size. If you need more power, the next step up is the 160 mm bore, which provides 10053 N of push force at 0.5 MPa. The integrated TC trunnion mounting is perfect for pivoting mechanisms, but remember that a standard cylinder drifts when air is lost or a valve is centered. The adjustable air cushion only decelerates the piston near stroke end; for secure load holding, you must add an external rod lock or a pilot-operated check valve. Since this model lacks the -S magnet, position sensing is not possible without changing to an -S variant.
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 SGC125X100TC FAQ
This 125 mm bore cylinder uses a G1/2 air port and delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, push increases to 8590 N and pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet. To use CMSG, DMSG, or EMSG magnetic switches, you must select the SGC125X100TC-S variant. The unit retains its ISO 15552 mounting interface and four steel tie-rod build regardless of magnet status.
