Airtac SGC Standard Cylinder SGC200X140S
The AirTAC Airtac SGC Standard Cylinder SGC200X140S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 140mm stroke, G3/4 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 SGC200X140S
Generating 15708 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious muscle to heavy machinery. The 200 mm bore design uses four steel tie rods to clamp the aluminium barrel to the covers, ensuring high structural rigidity under intense thrust loads. A two-way piston seal maintains an internal oil reservoir to continuously lubricate the seal for extended operational life.
Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position switches without any further modification. The G3/4 air port feeds the 40 mm chrome-plated rod, delivering a practical working load of roughly 9425 N. In vertical lifting scenarios, this equates to hoisting about 801 kg safely with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC200X140S Is Used
Automotive Press Stamping
Drives heavy stamping dies and holding fixtures on automotive assembly lines, utilizing the 15708 N push force to form sheet metal components reliably.
Palletizer Clamp Actuation
Actuates heavy-duty clamping arms in robotic palletizing cells, where the 140 mm stroke securely grips large palletized loads for transfer.
Injection Mould Extraction
Pushes thick-walled injection moulded parts out of large industrial presses, depending on the 801 kg vertical lift equivalence to strip heavy plastic goods.
Is the Airtac SGC Standard Cylinder SGC200X140S the Right Cylinder?
When sizing this 200 mm bore unit, consider stepping down to the 160 mm variant if your application only requires 10053 N of push force at 0.5 MPa. Conversely, if your fixture demands even more power, the 250 mm model outputs 24543 N under the same pressure. This specific 140 mm stroke length is well below the 500 mm threshold, so rod-bending side loads are less of a concern, though standard linear guidance is still advised for heavy offsets.
Remember that a standard pneumatic cylinder cannot hold a load in place if air pressure drops or the control valve is centred; the piston will drift. The adjustable 50 mm air cushions at both ends only serve to decelerate the piston near the end of stroke, acting strictly as end-of-travel dampers rather than holding brakes. For suspended loads that must remain fixed during an air loss event, incorporate an external rod lock or a pilot-operated check valve into your circuit.
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 SGC200X140S FAQ
This 200 mm bore cylinder features a 40 mm rod, a G3/4 port, and a 140 mm stroke. It delivers 15708 N push and 15079 N pull at 0.5 MPa, 21991 N push and 21110 N pull at 0.7 MPa, with a theoretical maximum force of 3204 kgf at 1.0 MPa. Operating speed ranges from 30-500 mm/s.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, meaning it drops directly into standard large-bore ISO 15552 fixtures and foot brackets. Additionally, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG electronic or reed switches directly onto the cylinder barrel.
