Airtac SGC Standard Cylinder SGC125X500SCA
The AirTAC Airtac SGC Standard Cylinder SGC125X500SCA is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 500mm 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 SGC125X500SCA
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore ISO 15552 tie-rod cylinder handles substantial linear work. 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 extended lifespan. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
This specific configuration includes a 500 mm stroke, a G1/2 air port, and an M27x2.0 rod thread. Because the code contains an S, it features a built-in piston magnet for CMSG, DMSG, or EMSG switches. The CA clevis mounting accessory provides a robust pivoting anchor point, and the standardized ISO 15552 mounting interface ensures it drops directly into existing large-bore fixtures.

Where the Airtac SGC Standard Cylinder SGC125X500SCA Is Used
Press Ejection
Provides the 6136 N push at 0.5 MPa needed to eject formed metal parts from a hydraulic stamping press bed.
Pallet Lowering
Uses the 500 mm stroke and CA clevis to lower heavy assembly pallets onto a conveyor line with controlled cushioning.
Material Gate
Actuates a heavy diverter gate in a bulk logistics hub, benefiting from the ISO 15552 mounting interface for simple fixture integration.
Is the Airtac SGC Standard Cylinder SGC125X500SCA the Right Cylinder?
When sizing this 125 mm bore unit, compare it against its neighbors: a larger 160 mm bore provides 10053 N of push at 0.5 MPa, while there is no smaller SGC option below 125 mm. The included -S magnet enables position sensing with CMSG, DMSG, or EMSG switches. The CA clevis mount is ideal for articulating loads.
Because this model features a 500 mm stroke, you must account for side-load and rod-bending risks; use an external guide or rod-end support to prevent premature seal wear. Note that the adjustable air cushion at both ends only decelerates the piston near stroke end—it does not act as a brake. If the application requires holding a load vertically when air is lost or the valve is centered, install an external rod lock or a pilot-operated check valve, as the piston will drift.
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 SGC125X500SCA FAQ
This 125 mm bore cylinder has 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 air cushion only decelerates the piston near the end of the stroke and does not function as a lock. The piston will drift if air is lost or the valve is centered; use an external rod lock or pilot-operated check valve for holding loads. The CA clevis and ISO 15552 mounting interface allow easy addition of external guidance.
