Airtac SGC Standard Cylinder SGC125X75N
The AirTAC Airtac SGC Standard Cylinder SGC125X75N is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 75mm 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 SGC125X75N
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious muscle to compact 75 mm stroke movements. It features a robust tie-rod build where four steel rods clamp the aluminium barrel to the covers, maintaining high rigidity under heavy thrust. The two-way piston seal retains an oil reservoir for continuous lubrication and long service life.
Because this configuration uses NBR seals, it is tailored for standard industrial environments rather than the high-temperature extremes a Viton option would handle. Plan for about 3682 N of real work at 0.5 MPa, which means it can safely lift roughly 313 kg vertically with a 2:1 safety margin. The G1/2 air port supplies the 125 mm bore, and it meets the ISO 15552 mounting interface for seamless fixture integration. Note that this specific SKU lacks a magnet, so it cannot support CMSG, DMSG or EMSG magnetic switches.

Where the Airtac SGC Standard Cylinder SGC125X75N Is Used
Press Die Ejection
Provides a compact 75 mm kick to eject formed metal parts from heavy stamping presses, utilizing the 6136 N push force to overcome die friction.
Pallet Stopper Gate
Acts as a rugged stop mechanism in high-throughput conveyor lines, absorbing pallet impacts with its rigid tie-rod construction and NBR seals.
Plastic Mold Clamping
Secures injection mold halves during low-travel clamping operations where a short, high-force stroke is required to hold the tooling shut.
Is the Airtac SGC Standard Cylinder SGC125X75N the Right Cylinder?
When sizing this NBR-sealed actuator, consider the neighbouring bores in the SGC family: stepping down is not an option within this large-frame series, while stepping up to the 160 mm bore yields 10053 N of push at 0.5 MPa. If your application requires position feedback, you must select the -S variant instead, as this base unit cannot host a sensing switch. Furthermore, if the load must remain suspended or fixed during air loss, do not rely on the end-of-stroke air cushion—it only decelerates the piston and will not act as a brake; install an external rod lock or a pilot-operated check valve for secure load holding.
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 SGC125X75N FAQ
This 125 mm bore cylinder features a G1/2 air port and a 32 mm rod with an M27x2.0 thread. It generates 6136 N push and 5734 N pull at 0.5 MPa, increasing to 8590 N push and 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
This specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. Additionally, the NBR seal option suits standard environments from -20 to +70 C; for 0-150 C high-temperature service, a Viton H seal would be required instead.
