Airtac SGC Standard Cylinder SGC125X1500SH
The AirTAC Airtac SGC Standard Cylinder SGC125X1500SH is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1500mm 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 SGC125X1500SH
Delivering 6136 N of push force at 0.5 MPa, this large-bore double-acting cylinder handles long 1500 mm strokes with a robust tie-rod design. Four steel rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for extended service life. The built-in -S magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
Because it uses the standardized ISO 15552 mounting interface, it drops seamlessly into existing large-bore fixtures. The H designation specifies Viton seals, extending the operating temperature range from -20 to +70 C up to 0-150 C for harsh thermal 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 SGC125X1500SH Is Used
Automotive Press Transfer
Moves heavy stamping blanks across a 1.5 m press bed, utilizing the Viton H seals to withstand radiant heat from nearby ovens.
High-Temperature Indexing Gate
Actuates a 1.5 m long material handling gate in a hot mill, relying on the 6136 N thrust and 0-150 C Viton capability.
Palletizer Pusher Assembly
Pushes industrial pallets along a conveyor, using the built-in magnet and EMSG sensor to confirm the full 1500 mm extension.
Is the Airtac SGC Standard Cylinder SGC125X1500SH the Right Cylinder?
When sizing this 125 mm bore against its neighbors, step down if the load is lighter or up if it exceeds safe limits. The next size up, the 160 mm bore, provides 10053 N of push at 0.5 MPa; since 125 mm is the smallest SGC option, there is no smaller bore in this series. For this 1500 mm maximum standard stroke, external guide support is critical to prevent rod bending and side-load damage during extension.
The air cushions at both ends decelerate the piston near stroke end but do not function as a lock. If the application requires holding a vertical load when air is lost or the valve is centered, add an external rod lock or a pilot-operated check valve to prevent drift. The G1/2 port and M27x2.0 rod thread match the standard 125 mm bore architecture.
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 SGC125X1500SH FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
No, the adjustable air cushions only decelerate the piston near the stroke ends and do not act as a braking mechanism. The piston will drift if air is lost or the valve is centered; you must use an external rod lock or pilot-operated check valve to hold a load.
