About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X280TC
The AirTAC SC160X280TC is a double-acting pneumatic cylinder delivering substantial force for heavy-duty industrial automation. At 0.5 MPa, this 160mm bore unit generates 10053 N pushing and 9425 N pulling, scaling up to a powerful 18095 N push force at the maximum operating pressure of 0.9 MPa.
This model features a 280mm stroke with a 40mm diameter piston rod and M36x2 knuckle thread. It includes a factory-fitted centre trunnion mount (TC) with the TCM1 bracket (F-SC160TC), allowing the cylinder to pivot during operation. The adjustable pneumatic cushion at each end, with a 29mm cushion length, decelerates the piston smoothly to absorb energy.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X280TC Is Used
Heavy Pressing & Clamping
The 18095 N maximum thrust at 0.9 MPa makes this cylinder ideal for hydraulic-style clamping, riveting, and heavy-duty pressing fixtures in metal fabrication.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder body to swing, making it perfect for actuating diverter gates and sorting paddles on high-capacity material handling conveyors.
Large Mould Ejection
With a robust 40mm rod and high force output, this cylinder reliably ejects large plastic or rubber parts from heavy moulds, where a rigid, guided ejection stroke is critical.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X280TC the Right Cylinder?
Select the SC160 for applications requiring force in the 10,000-18,000 N range. If your load demands more force, step up to the SC200 bore, which provides 15708 N at 0.5 MPa. For lighter, faster cycles, the SC125 bore offers 6136 N at the same pressure.
When replacing an existing cylinder, match these five points: 160mm bore, 280mm stroke, PT3/4 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and no magnet. For this 280mm stroke, ensure the rod is not subjected to radial or side loads; if side loading is unavoidable, use an external linear guide to prevent rod bending and premature seal wear.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac AIRTAC SC125-160 Standard Cylinder SC160X280TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N.
Yes. The TC suffix in SC160X280TC specifies a centre trunnion mount, which is supplied complete with the TCM1 trunnion bracket (accessory code F-SC160TC). This allows the cylinder to pivot around its centre point.
