About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350TC
The AirTAC SC125X350TC is a double-acting single-rod pneumatic cylinder delivering 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa max operating pressure). Its 32 mm diameter piston rod and 28 mm adjustable air cushion are engineered for heavy linear actuation over a 350 mm stroke.
This model is configured with a TC centre trunnion mount (supplied with TCM1 bracket, accessory code F-SC125TC), allowing the cylinder to pivot during operation. The body length A is 203 mm, giving an extended length of approximately 553 mm. Operating pressure is 0.15-1.0 MPa with a speed range of 30-500 mm/s, conforming to the ISO 6430 class for large-bore cylinders.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350TC Is Used
Heavy Part Transfer
Pushes or lifts large castings and weldments on indexing conveyors, using the 6136 N force at 0.5 MPa to move heavy payloads reliably.
Press & Clamp Fixtures
Applies up to 11045 N of clamping force at 0.9 MPa in hydraulic-replacement pneumatic press fixtures for assembly and forming operations.
Pivoting Conveyor Gates
The TC centre trunnion mount allows the cylinder to swing, making it ideal for actuating diverter gates and chutes on material handling lines.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350TC the Right Cylinder?
Choose the SC125 when your application needs force in the 6136 N (push at 0.5 MPa) class. If you can accept a lower force of 3927 N, stepping down to the SC100 bore reduces size and air consumption. For higher demand, the SC160 bore provides 10053 N at 0.5 MPa.
At a 350 mm stroke, ensure side loads are managed—long unsupported strokes on a single rod can create bending moments. Use an external guide rail or a guided cylinder if the load is not perfectly axial. For direct replacement, match these five points: 125 mm bore, 350 mm stroke, PT port thread, TC centre trunnion mounting, and no magnet.
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 SC125X350TC FAQ
At 0.5 MPa the push force is 6136 N and pull force is 5734 N. At 0.7 MPa push reaches 8590 N, and at the maximum operating pressure of 0.9 MPa it delivers 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than ISO 15552 profile cylinders. The 125-250 bore range conforms to ISO 6430 class dimensions. It will only directly interchange with another AirTAC SC125 tie-rod cylinder matching the 350 mm stroke, PT ports, and TC trunnion mount.
