Airtac SGC Standard Cylinder SGC125X135TC
The AirTAC Airtac SGC Standard Cylinder SGC125X135TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 135mm 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 SGC125X135TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for heavy automation. 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. A G1/2 port supplies the 125 mm bore, which also generates 8590 N at 0.7 MPa.
Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. For real-world sizing, plan for about 3682 N of actual work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The unit includes a 40 mm adjustable air cushion at both ends and a TC trunnion mounting interface.

Where the Airtac SGC Standard Cylinder SGC125X135TC Is Used
Press Ejection
Provides the 6136 N push at 0.5 MPa needed to knock stamped metal parts out of a die, using the 135 mm stroke to clear the press bed quickly.
Pallet Diverting
Uses the TC trunnion mount to pivot a heavy diverter arm on a packaging line, handling the lateral force required to redirect loaded pallets.
Gate Actuation
Opens and closes large bulk-material chute gates, relying on the tie-rod construction to maintain rigidity under the weight of aggregate material.
Is the Airtac SGC Standard Cylinder SGC125X135TC the Right Cylinder?
When sizing this 125 mm bore against the SGC family, step down to a smaller bore if your load is lighter, or move up to the 160 mm bore (10053 N push at 0.5 MPa) if you need significantly more thrust. The included TC trunnion mount utilizes the standardized ISO 15552 mounting interface, allowing it to drop directly into existing large-bore fixtures and matching accessories.
Remember that a standard cylinder drifts when air is lost or the valve is centered; the end cushions only decelerate the piston near stroke end and do not act as a brake. For suspended or vertical loads that must be held in place during a pressure drop, integrate 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 SGC125X135TC 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. You must select an -S variant to use CMSG, DMSG, or EMSG magnetic switches. However, all SGC models are dimensionally interchangeable per the ISO 15552 mounting interface, simplifying fixture design.
