Airtac SGC Standard Cylinder SGC125X150N
The AirTAC Airtac SGC Standard Cylinder SGC125X150N is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGC125X150N
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder brings large-bore power to ISO 15552 mounting fixtures. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for long mechanical life. The NBR seal option equips this 125 mm bore unit for broad temperature duties from -20 to +70 C, and the G1/2 port matches the standard airflow for this size class.
Because it carries no piston magnet, this specific SKU cannot host CMSG, DMSG or EMSG 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. The 150 mm stroke moves smoothly across the 30-500 mm/s speed range, decelerated by 40 mm adjustable air cushions at both ends.

Where the Airtac SGC Standard Cylinder SGC125X150N Is Used
Press Fit Assembly
Drives 150 mm strokes to seat bearings into automotive housings, utilizing the 6136 N push force at 0.5 MPa for reliable insertion.
Pallet Diverting
Actuates heavy-duty routing gates on packaging lines, where the NBR seals withstand ambient factory temperatures and the tie-rod build absorbs shock.
Material Lift Gate
Raises and lowers loading bay gates, safely managing vertical loads up to 313 kg with a 2:1 margin before external guides take the weight.
Is the Airtac SGC Standard Cylinder SGC125X150N the Right Cylinder?
When sizing this 125 mm bore unit, verify if the 6136 N push at 0.5 MPa provides enough thrust, or if stepping up to the 160 mm bore (10053 N) is necessary for heavier loads. As the smallest bore in the SGC family, it serves as the entry point for large-bore applications. Remember that a standard cylinder drifts when air is lost or a valve centers; the end cushions only decelerate the piston and will not hold a suspended load, so specify an external rod lock or pilot-operated check valve if position holding is required. Since this SKU lacks the -S magnet, magnetic sensing is impossible without changing to an -S variant.
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 SGC125X150N 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, because this model lacks the -S suffix, it has no internal piston magnet and cannot support CMSG, DMSG or EMSG switches. It is built with an ISO 15552 mounting interface for fixture interchangeability and uses NBR seals rated for -20 to +70 C.
