Airtac SGC Standard Cylinder SGC125X1000SFTC
The AirTAC Airtac SGC Standard Cylinder SGC125X1000SFTC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm 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 SGC125X1000SFTC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore ISO 15552 tie-rod cylinder is engineered for heavy-duty automation. Four steel tie rods clamp the aluminum barrel to the front and rear covers, providing the high rigidity needed to handle large-bore thrust without flexing. The internal two-way piston seal maintains an oil reservoir for continuous lubrication and extended service life.
Because the -S suffix equips this unit with a piston magnet, it supports CMSG, DMSG and EMSG position switches for end-of-stroke detection. Plan for roughly 3682 N of actual work at 0.5 MPa, which translates to lifting about 313 kg vertically with a 2:1 safety margin. The G1/2 air port feeds the 125 mm bore, and the integrated FTC trunnion mounting interface simplifies alignment on long-stroke articulated setups.

Where the Airtac SGC Standard Cylinder SGC125X1000SFTC Is Used
Pallet Transfer Line
Indexes heavy timber pallets along a 1000 mm conveyor bed, utilizing the 6136 N thrust to push loads firmly into the next processing station.
Automated Warehousing
Deploys the FTC trunnion mount and 1000 mm stroke to actuate large sliding safety gates or heavy-duty diverter arms within high-bay storage systems.
Press Ejection
Ejects formed metal components from a hydraulic press, relying on the CMSG sensor magnet to confirm full retraction before the next cycle begins.
Is the Airtac SGC Standard Cylinder SGC125X1000SFTC the Right Cylinder?
When sizing this 125 mm bore option, verify if the 6136 N push force at 0.5 MPa is sufficient, or if stepping up to the 160 mm bore (10053 N) is necessary for your application; there is no smaller SGC bore below 125. For a 1000 mm stroke, preventing rod bending and side-load damage is critical—ensure external guide rails support the load, as the piston rod alone should not bear lateral cantilever forces. The FTC trunnion mount helps absorb angular misalignment during long-travel articulation.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near the end of travel and acts purely as a shock absorber, not a braking device. To suspend a vertical load safely during an emergency stop or pressure drop, install an external pilot-operated check valve or a dedicated pneumatic rod lock.
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 SGC125X1000SFTC FAQ
The 125 mm bore generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port, a 32 mm piston rod, and features a 40 mm adjustable air cushion at both ends.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, meaning it drops directly into standard large-bore fixtures and trunnion accessories like the FTC mount. Because this SKU includes the -S magnet option, it fully supports CMSG, DMSG, and EMSG reed or electronic switches for position sensing.
