Airtac SGC Standard Cylinder SGC125X190S
The AirTAC Airtac SGC Standard Cylinder SGC125X190S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 190mm 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 SGC125X190S
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder brings large-bore power to demanding setups. The 125 mm bore uses a G1/2 port and an M27x2.0 rod thread, while four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity. Because it follows the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom bracketry.
This 190 mm stroke variant includes a built-in piston magnet (-S) for direct CMSG, DMSG or EMSG switch mounting. A heterogeneous two-way piston seal maintains an internal oil reservoir for long life. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin.

Where the Airtac SGC Standard Cylinder SGC125X190S Is Used
Press Ejection
Provides the robust 6136 N push force needed to eject formed metal parts from heavy stamping presses.
Pallet Stopping
Acts as a heavy-duty end-stop for loaded pallets on conveyor lines, absorbing kinetic energy via its 40 mm adjustable air cushion.
Lift Gate Actuation
Drives the 190 mm extension stroke on industrial lift gates, moving loads safely within its 313 kg vertical lift capacity.
Is the Airtac SGC Standard Cylinder SGC125X190S the Right Cylinder?
When sizing this unit against the SGC family, dropping down to a smaller bore is not an option as 125 mm is the minimum. If your application requires more power, stepping up to the 160 mm bore yields 10053 N of push at 0.5 MPa. Since this 190 mm stroke is under the 500 mm side-load threshold, standard mounting is generally safe, but always ensure rigid alignment to prevent premature seal wear.
Remember that a standard SGC cylinder will drift and lose its position if air pressure drops or the valve is centred; the adjustable air cushion only decelerates the piston near the end of stroke and does not function as a locking brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your pneumatic 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 SGC125X190S FAQ
This 125 mm bore model 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 of 1251 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet, allowing direct mounting of CMSG, DMSG or EMSG switches. Additionally, its tie-rod construction adheres to the ISO 15552 mounting interface, ensuring dimensional interchangeability with standard large-bore fixtures and accessories.
