About the Airtac SGC Standard Cylinder SGC125X155TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder is built on a genuine ISO 15552 mounting interface, ensuring it drops directly into standard fixtures. 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 long service life. The unit features a 155 mm stroke, a G1/2 air port, and a 32 mm carbon steel rod with a 20 µm hard chrome plating.
Because this SKU lacks the -S magnet option, it cannot host CMSG, DMSG, or EMSG position switches. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. Adjustable air cushions at both ends provide 40 mm of deceleration to protect the end caps.

Where the Airtac SGC Standard Cylinder SGC125X155TC Is Used
Press Fit Tooling
Drives small bearing and bushing presses where 6136 N of thrust at 0.5 MPa is sufficient to seat components without damaging housings.
Pallet Diverter
Actuates a heavy-duty diverter arm on a packaging line, utilizing the 155 mm stroke to push pallets onto a secondary routing lane.
Lift Gate Actuation
Raises and lowers a loading dock safety gate, safely managing vertical loads up to 313 kg with a 2:1 safety margin at 0.5 MPa.
Is the Airtac SGC Standard Cylinder SGC125X155TC the Right Cylinder?
When sizing this 125 mm bore option, verify if the 6136 N push at 0.5 MPa provides adequate thrust, or if you should step up to the 160 mm bore (10053 N). If your application requires less force, note that 125 mm is the smallest available SGC size. The TC trunnion mounting interface supplied here is ideal for pivoting loads, but ensure your mounting hardware matches the ISO 15552 dimensions.
Since this specific model has no -S suffix, it cannot accept magnetic sensors; you will need to specify an -S variant if your control system requires position feedback. Furthermore, a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, so install an external rod lock or pilot-operated check valve if you need to hold a suspended load safely.
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 SGC125X155TC FAQ
This 125 mm bore cylinder features a G1/2 air port and generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, meaning it cannot support CMSG, DMSG, or EMSG switches. You must select an SGC125X155TC-S variant if your application requires electronic position feedback. The tie-rod construction and ISO 15552 mounting interface remain identical.
