Airtac SGC Standard Cylinder SGC125X485S
The AirTAC Airtac SGC Standard Cylinder SGC125X485S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 485mm 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 SGC125X485S
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious thrust to automated lines. The SGC125X485S is built on a genuine ISO 15552 mounting interface, meaning it drops directly into existing large-bore fixtures without custom bracketry. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed to handle heavy loads without flexing. A two-way piston seal maintains an internal oil reservoir for continuous lubrication and extended service life.
Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing. 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 G1/2 air port feeds the 32 mm chrome-plated rod, and the standard TPU seals handle temperatures from -20 to +70 C. For hotter environments up to 150 C, Viton H seals are available.

Where the Airtac SGC Standard Cylinder SGC125X485S Is Used
Press Fit Assembly
Drives bearings into heavy machinery housings, utilizing the 6136 N push force to seat components firmly without hydraulic fluid.
Pallet Stopper Gate
Acts as a heavy-duty pneumatic stop on converging roller conveyors, holding back loaded pallets weighing up to 313 kg vertically.
Large Carton Flapper
Extends 485 mm to fold heavy corrugated flaps on industrial packaging lines, using the -S magnet to confirm stroke completion.
Is the Airtac SGC Standard Cylinder SGC125X485S the Right Cylinder?
When sizing this 125 mm bore unit, compare your actual load against its 6136 N push and 5734 N pull ratings at 0.5 MPa. If your application requires less force, stepping down is not possible within the SGC series as 125 mm is the smallest available bore. If you need substantially more thrust, the 160 mm bore provides 10053 N of push force at the same pressure. This 485 mm stroke approaches the longer end of the standard range, so ensure your mechanism provides adequate external guidance to prevent rod bending under side loads. The built-in magnet allows seamless integration with CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation.
Remember that the adjustable 40 mm air cushion only decelerates the piston near the end caps; it does not function as a brake. If air pressure drops or the valve is centered, the piston will drift. For vertical or suspended loads that must remain held during air loss, you must add an external rod lock or a pilot-operated check valve to the system.
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 SGC125X485S FAQ
This 125 mm bore cylinder features a G1/2 air port and delivers 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.
Yes, the tie-rod construction is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to use standard FA flanges or TC trunnions. Additionally, the -S suffix indicates a built-in piston magnet, enabling direct mounting of CMSG, DMSG, or EMSG electronic switches.
