Airtac SGC Standard Cylinder SGC125X450S
The AirTAC Airtac SGC Standard Cylinder SGC125X450S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 450mm 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 SGC125X450S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles large automation tasks with a 450 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 to maximize service life. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG electronic or reed switches for precise end-position detection.
With a 125 mm bore and a G1/2 air port, it operates at speeds of 30-500 mm/s. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. The standard TPU seal handles temperatures from -20 to +70 C, though a Viton H option extends this range up to 150 C for high-heat environments.

Where the Airtac SGC Standard Cylinder SGC125X450S Is Used
Pallet Diversion
Actuates heavy-duty lane diverters on packaging lines, utilizing the 450 mm stroke to push fully loaded pallets sideways onto parallel conveyors.
Roller Gate Operation
Opens and closes large automated warehouse security gates, where the 6136 N thrust at 0.5 MPa easily overcomes the high rolling resistance of heavy doors.
Press Ejection
Ejects dense formed metal parts from hydraulic presses, relying on the rigid tie-rod construction to absorb sudden impact loads without barrel deflection.
Is the Airtac SGC Standard Cylinder SGC125X450S the Right Cylinder?
When sizing this unit, verify if the 6136 N push at 0.5 MPa provides adequate thrust, as there is no smaller SGC bore below 125 mm. If your application requires significantly more power, stepping up to the 160 mm bore yields 10053 N of push force. Because this model features a 450 mm stroke, mounting stability is critical: ensure your fixture prevents side-loading and rod bending by using guided external rails rather than relying solely on the piston rod for lateral support.
This SKU includes the -S magnet for CMSG/DMSG/EMSG sensors. Remember that a standard cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near the end of travel and acts purely as an end-of-stroke buffer, never as a holding brake. To suspend a vertical load safely, integrate an external pilot-operated check valve or a dedicated rod lock.
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 SGC125X450S FAQ
This 125 mm bore cylinder features a G1/2 air port and a 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.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into existing large-bore fixtures. You can use standard LB foot, FA flange, or TC trunnion mounts, and the -S magnet allows direct mounting of CMSG, DMSG, or EMSG sensors.
