Airtac SGC Standard Cylinder SGC125X1090SH
The AirTAC Airtac SGC Standard Cylinder SGC125X1090SH is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1090mm 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 SGC125X1090SH
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator utilizes a robust tie-rod build where four steel rods clamp the aluminum barrel to the end covers. The Viton H seal option equips this specific SKU for high-temperature environments up to 150 C, while the two-way piston seal maintains an internal oil reservoir for extended operational life. A built-in piston magnet (-S) enables seamless integration with CMSG, DMSG, or EMSG electronic switches.
With a 1090 mm stroke, plan for approximately 3682 N of real work at 0.5 MPa, which translates to lifting about 313 kg vertically with a 2:1 safety margin. The G1/2 port and M27x2.0 rod thread handle the airflow and mounting demands of this class. Because it adheres to the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without requiring custom bracketry.

Where the Airtac SGC Standard Cylinder SGC125X1090SH Is Used
Automotive Press Ejection
Ejects formed sheet metal panels from heated hydraulic presses, utilizing the Viton H seal to withstand ambient radiant heat up to 150 C while pushing with 6136 N.
Palletizer Lowerator
Lowers heavy product layers onto stacking pallets over a 1090 mm travel distance, safely managing vertical loads around 313 kg with a 2:1 safety margin.
High-Temp Door Actuation
Opens and closes heavy industrial furnace doors, relying on the tie-rod construction for structural rigidity and the DMSG sensors to confirm door position.
Is the Airtac SGC Standard Cylinder SGC125X1090SH the Right Cylinder?
When sizing this 125 mm bore, consider stepping down or up based on your exact force requirements. If your application needs less force, there is no smaller SGC bore available, so you would need to look outside the series. If you need more power, the 160 mm bore provides 10053 N of push at 0.5 MPa. For this 1090 mm stroke, adding external guide rails is critical to prevent rod bending and premature seal wear under side loads.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the adjustable 40 mm air cushions at both ends only decelerate the piston near stroke end and do not function as a locking brake. To suspend a load safely mid-stroke, install an external rod lock or a pilot-operated check valve.
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 SGC125X1090SH FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. It generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, the double-acting piston will drift if air pressure is lost or the directional valve is centered. The adjustable air cushions at both ends only serve to decelerate the piston near the stroke limits and do not act as a brake. You must use an external rod lock or pilot-operated check valve to hold a suspended load.
