Airtac SGC Standard Cylinder SGC125X650SH
The AirTAC Airtac SGC Standard Cylinder SGC125X650SH is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 650mm 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 SGC125X650SH
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles large-bore automation with a 650 mm stroke. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for long mechanical life. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
Equipped from the factory with Viton H seals, the operating temperature range extends from 0 to 150 C for high-heat environments. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG position switches. Pneumatic connection is made via a G1/2 port, and the M27x2.0 rod thread interfaces with standard knuckles.

Where the Airtac SGC Standard Cylinder SGC125X650SH Is Used
Injection Mold Ejection
Pushes heavy injection molds at elevated ambient temperatures using Viton H seals rated for 150 C, relying on the 650 mm stroke to fully clear the tooling.
Pallet Discharge Station
Exerts 6136 N at 0.5 MPa to push loaded pallets onto a transfer chain, safely handling roughly 313 kg of vertical mass with a 2:1 margin.
High-Tamp Metal Forming
Actuates heavy press blanks over 650 mm with a G1/2 port, using the ISO 15552 mounting interface to drop into existing heavy-duty tooling fixtures.
Is the Airtac SGC Standard Cylinder SGC125X650SH the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-frame family. If 6136 N at 0.5 MPa is excessive, no smaller SGC bore exists, requiring a different series altogether. If more thrust is required, stepping up to the 160 mm bore yields 10053 N at 0.5 MPa. Because the 650 mm stroke is substantial, external guide rails should be fitted to prevent rod bending and absorb side loads. Remember that standard air cushions only decelerate the piston near stroke end; to prevent drift and hold a load vertically when air is lost or valves are centered, an external rod lock or pilot-operated check valve is required.
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 SGC125X650SH 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 is G1/2 and the rod thread is M27x2.0.
Yes, the -S suffix denotes a built-in piston magnet that allows CMSG, DMSG, and EMSG switches to track position. The H suffix indicates Viton seals, raising the operating temperature limit to 150 C. The ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures.
