Airtac SGC Standard Cylinder SGC125X1200
The AirTAC Airtac SGC Standard Cylinder SGC125X1200 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1200mm 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 SGC125X1200
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore ISO 15552 tie-rod cylinder is built for demanding automation tasks. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 port and M27x2.0 rod thread handle the required air volume efficiently.
Because this model lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For position feedback, external limit switches must be used. Plan for about 3682 N of real work at 0.5 MPa, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin.

Where the Airtac SGC Standard Cylinder SGC125X1200 Is Used
Pallet Transfer Line
Pushes heavy loaded pallets over the 1200 mm stroke on a packaging conveyor, utilizing the 6136 N thrust at 0.5 MPa.
Automated Warehousing
Acts as a long-reach pusher in automated storage and retrieval systems to shift 300 kg tote bins between roller lanes.
Stamping Feed Mechanism
Advances heavy steel blanks into a mechanical press, relying on the rigid tie-rod construction to maintain alignment.
Is the Airtac SGC Standard Cylinder SGC125X1200 the Right Cylinder?
When sizing this 125 mm bore unit, note that it is the smallest in the SGC family, so the next step up is the 160 mm bore delivering 10053 N at 0.5 MPa. If your application requires less force, you would need to look outside the SGC large-bore range. This 1200 mm stroke requires careful external guiding to prevent rod bending under side loads. Additionally, the air cushions only decelerate the piston near the stroke ends; they do not act as a brake, so an external rod lock or pilot-operated check valve is required to hold a load securely if air pressure is lost.
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 SGC125X1200 FAQ
This 125 mm bore cylinder features a G1/2 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 is 8590 N and the pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot support CMSG, DMSG, or EMSG magnetic switches. You must use external mechanical or proximity switches. The unit is dimensionally interchangeable per the ISO 15552 mounting interface for easy fixture integration.
