Airtac SGC Standard Cylinder SGC125X400TC
The AirTAC Airtac SGC Standard Cylinder SGC125X400TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 400mm 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 SGC125X400TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore automation. Four steel tie rods clamp the aluminum barrel to the covers, providing high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service 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.
The 125 mm bore uses a G1/2 port, a Ø32 mm hard-chrome rod, and M27x2.0 rod threads. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. The TC trunnion mounting interface makes it dimensionally interchangeable with standard ISO 15552 large-bore fixtures, and the adjustable 40 mm air cushions at both ends absorb end-of-stroke impact.

Where the Airtac SGC Standard Cylinder SGC125X400TC Is Used
Press Ejection
Provides the robust 6136 N push stroke needed to eject formed metal parts from heavy stamping presses.
Pallet Diversion
Uses the TC trunnion mount to pivot and divert heavy logistics pallets along high-throughput packaging lines.
Lift Gate Actuation
Raises and lowers loaded warehouse lift gates, safely moving components weighing up to 313 kg vertically.
Is the Airtac SGC Standard Cylinder SGC125X400TC the Right Cylinder?
When sizing this 400 mm stroke model, verify if the next bore down or up fits your space: there is no smaller SGC bore, while the 160 mm bore raises push force to 10053 N at 0.5 MPa. At 400 mm of travel, guide the load externally to prevent rod bending and side-load wear. The TC trunnion mount suits pivoting loads, but remember a plain cylinder drifts when air is lost or the valve is centered; the air cushion only decelerates the piston near stroke end, so add an external rod lock or pilot-operated check valve if you need to hold a suspended load. To use magnetic sensors, you must switch to the -S variant, as this base SKU has no magnet.
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 SGC125X400TC FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
Yes, the tie-rod build and TC trunnion interface are dimensionally interchangeable per the ISO 15552 mounting standard. However, because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches without upgrading to the magnet-equipped variant.
