Airtac SGC Standard Cylinder SGC125X125SH
The AirTAC Airtac SGC Standard Cylinder SGC125X125SH is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 125mm 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 SGC125X125SH
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore industrial tasks. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 port and M27x2.0 rod thread streamline integration into existing setups.
Equipped with a -S piston magnet, the unit supports CMSG, DMSG, and EMSG switches for position sensing. The H seal option provides Viton FKM elastomers, extending the operating temperature range from -20 to +70 C up to 0-150 C for high-heat environments. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC125X125SH Is Used
Press Fit Assembly
Drives bearings into heavy housings using the 8590 N push force available at 0.7 MPa.
Pallet Lift Station
Elevates 300 kg material platforms using the 125 mm bore within high-temperature logistics hubs.
Plastic Mould Eject
Ejects formed thermoplastic parts from heated machinery utilizing the 0-150 C Viton H seal.
Is the Airtac SGC Standard Cylinder SGC125X125SH the Right Cylinder?
When sizing this 125 mm bore, moving down is not an option within the SGC family, but stepping up to the 160 mm bore increases the 0.5 MPa push force to 10053 N. For maintaining vertical position during air loss, note that a standard cylinder drifts; the 40 mm adjustable air cushions only decelerate the piston near stroke ends. An external rod lock or pilot-operated check valve is required to hold a suspended load. The included magnet matches perfectly with CMSG, DMSG, or EMSG sensors.
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 SGC125X125SH FAQ
This 125 mm bore cylinder features a G1/2 port and generates 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
