About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X120TC
The SC125X120TC is a double-acting tie-rod cylinder configured with a centre trunnion mount (TC) for pivoting applications. With a 125 mm bore and 120 mm stroke, it generates 6136 N of push force and 5734 N pull force at 0.5 MPa, rising to 11045 N push at the maximum operating pressure of 0.9 MPa.
This model features a 32 mm piston rod with M27x2 knuckle thread and PT1/2 ports. The adjustable air cushion is 28 mm long, and the total extended body length is approximately 323 mm (body length A=203 mm + 120 mm stroke). The TC mount ships with the TCM1 trunnion bracket (F-SC125TC) for secure mid-body pivoting.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X120TC Is Used
Heavy Press & Clamping
Delivers over 11000 N at 0.9 MPa for powerful clamping, pressing, and forming operations in metal fabrication cells.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder body to pivot, ideal for actuating diverter gates and sorting flaps on heavy-duty conveyor lines.
Industrial Lift & Tilt
Provides the high force and pivoting motion required for tilting bins, lifting platforms, and positioning heavy weldments in assembly stations.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X120TC the Right Cylinder?
Select the SC125X120TC when your application needs a pivoting cylinder with substantial force. The 125 mm bore provides 6136 N at 0.5 MPa; if you need less force, step down to the 100 mm bore (3927 N at 0.5 MPa). For higher force, the 160 mm bore delivers 10053 N at the same pressure. The centre trunnion mount allows the cylinder to swing during actuation—ensure the pivot axis is aligned and the trunnion pins are sized for the full thrust load.
For a direct replacement, match these five points: 125 mm bore, 120 mm stroke, PT1/2 port thread, centre trunnion (TC) mounting, and no magnet. This is an ISO 6430 class tie-rod cylinder; dimensional interchangeability is limited to other AirTAC SC125 tie-rod units with identical mounting.
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 SC125X120TC FAQ
At 0.5 MPa supply pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. The body length is shorter, so mounting dimensions differ. Only replace another AirTAC SC125 tie-rod cylinder with matching bore, stroke, PT port, and centre trunnion mount.
