Airtac SGC Standard Cylinder SGC125X1100
The AirTAC Airtac SGC Standard Cylinder SGC125X1100 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1100mm 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 SGC125X1100
Generating 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles long 1100 mm strokes with a G1/2 air port. Four steel tie rods clamp the aluminium barrel to the covers for high rigidity, while a two-way piston seal maintains an internal oil reservoir for extended operational life. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
As a double-acting single-rod actuator, it uses adjustable 40 mm air cushions at both ends to decelerate the payload smoothly. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches; sensing requires the -S variant. The standard TPU seal handles temperatures from -20 to +70 C, with Viton H available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X1100 Is Used
Elevator Stage Lifting
Raises heavy platform stages or scissor lifts through a 1100 mm travel distance, utilizing the 6136 N push force to move structural components vertically.
Long-Transfer Pusher
Transfers large pallets or heavy assemblies down an extended material handling line, relying on the rigid tie-rod construction to maintain alignment over the long stroke.
High-Bay Extraction
Extracts heavy totes or machinery parts from deep storage racking, where the full 1100 mm extension reaches deep into shelving units.
Is the Airtac SGC Standard Cylinder SGC125X1100 the Right Cylinder?
When sizing this 125 mm bore actuator, compare your load against the available thrust: stepping up to the 160 mm bore yields 10053 N at 0.5 MPa, while there is no smaller SGC option below 125 mm. For a 1100 mm stroke, external guide rails are strongly recommended to prevent rod bending and absorb side loads during extended reaches. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the air cushion only decelerates the piston near stroke end and will not hold a load vertically. For suspended loads, install an external rod lock or a pilot-operated check valve.
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 SGC125X1100 FAQ
This 125 mm bore cylinder 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.
No, this specific SKU does not include a magnet. To use CMSG, DMSG, or EMSG magnetic switches, you must select the -S variant. Additionally, its ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures and accessories.
