Airtac SGC Standard Cylinder SGC125X650TC
The AirTAC Airtac SGC Standard Cylinder SGC125X650TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 650mm 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 SGC125X650TC
Generating 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator utilizes a robust tie-rod design where four steel rods clamp the aluminum barrel to the covers. Because it adheres to the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom brackets. The G1/2 port and M27x2.0 rod thread supply ample airflow and anchoring for the 650 mm stroke.
For practical sizing, 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 two-way piston seal maintains an internal oil reservoir for long life, while the default TPU elastomer handles temperatures from -20 to +70 C. Note that this specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG or EMSG sensors for position feedback.

Where the Airtac SGC Standard Cylinder SGC125X650TC Is Used
Pallet Diversion
Uses the 6136 N thrust to push heavy pallets onto parallel conveyor lanes, absorbing end-impact via the 40 mm adjustable air cushion.
Roller Gate Actuation
Leverages the 650 mm stroke to open and close large warehouse loading bay roller gates, relying on the TC trunnion to handle pivot stress.
Tine Positioner
Shifts heavy fork tine carriages horizontally on industrial forklifts, taking advantage of the 313 kg safe vertical lift equivalence.
Is the Airtac SGC Standard Cylinder SGC125X650TC the Right Cylinder?
When sizing this 125 mm bore, consider stepping down if your load is light, though this is the smallest option in the SGC family. Moving up to the 160 mm bore yields 10053 N of push at 0.5 MPa if your application outgrows the 125 mm capacity. The included TC trunnion mount suits pivoting articulations, but remember that a plain cylinder drifts when air is lost or the valve is centered; the end cushions only decelerate the piston and do not act as a brake, so deploy an external rod lock or pilot-operated check valve for suspended loads.
With a 650 mm stroke, the 32 mm rod requires external guidance to prevent side-load bending and premature seal wear. Always ensure the moving payload is supported by linear rails rather than the cylinder rod itself.
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 SGC125X650TC FAQ
This 125 mm bore cylinder features a G1/2 air port. 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 force of 1251 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG or EMSG switches. You must use external mechanical or pneumatic limit valves for position feedback.
