Airtac SGC Standard Cylinder SGC125X100SH
The AirTAC Airtac SGC Standard Cylinder SGC125X100SH is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGC125X100SH
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder is built around a genuine ISO 15552 mounting interface for direct fixture and accessory interchangeability. Four steel tie rods clamp the aluminum barrel to the covers, providing the rigidity needed to handle large-bore thrust, while a two-way piston seal maintains an internal oil reservoir for long service life. Equipped with a G1/2 port and an M27x2.0 rod thread, it operates at speeds of 30-500 mm/s with 40 mm adjustable air cushions at both ends.
Because the SKU includes the -S suffix, a built-in piston magnet enables position sensing with CMSG, DMSG, or EMSG switches. The H designation specifies a Viton (FKM) seal, raising the operating temperature ceiling from 70 C up to 150 C for high-heat environments. Plan for roughly 3682 N of real work at 0.5 MPa, which equates to lifting about 313 kg vertically with a 2:1 safety margin.

Where the Airtac SGC Standard Cylinder SGC125X100SH Is Used
Plastic Injection Mold Clamping
Applies steady 6136 N clamping pressure on mid-sized injection mold tooling, utilizing the Viton seal to withstand ambient radiant heat from heated platens.
Heavy Pallet Positioning
Indexes loaded pallets along a conveyor line, relying on the -S magnet and EMSG sensors to confirm stroke endpoints for automated packaging sequences.
Automated Press Ejection
Ejects formed metal components from a hydraulic press, absorbing end-of-stroke impact using the 40 mm adjustable air cushions to protect the 32 mm rod.
Is the Airtac SGC Standard Cylinder SGC125X100SH the Right Cylinder?
If 6136 N of thrust is excessive for your payload, dropping down is not an option within the SGC family as the 125 mm bore is the smallest available size. Stepping up to the 160 mm bore increases the 0.5 MPa push force to 10053 N if your application demands more power. For this 100 mm stroke, side-load risks are minimal, but always ensure rigid mounting using LB foot, FA flange, or TC trunnion brackets. Remember that the air cushions only decelerate the piston near the stroke ends; they do not act as a brake. If the load must be held vertically during air loss or valve centering, install an external rod lock or a pilot-operated check valve to prevent drift.
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 SGC125X100SH FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. The air port size is G1/2.
No, the standard SGC design does not hold position on air loss. The adjustable cushions only decelerate the piston near the end of travel. You must add an external rod lock or pilot-operated check valve to prevent vertical drift.
