About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X140TC
The AirTAC SC125X140TC is a double-acting tie-rod cylinder with a 125 mm bore and 140 mm stroke, factory-supplied with a centre trunnion (TC) mount and matching TCM1 bracket for pivoting applications. It generates 6136 N of push force and 5734 N of pull force at 0.5 MPa, rising to 11045 N at the maximum operating pressure of 0.9 MPa.
This ISO 6430 class cylinder uses a 32 mm diameter piston rod with M27×2 male threads and PT1/2 ports. The adjustable air cushion at each end (28 mm cushion length) decelerates the piston smoothly, while the TPU/NBR seals support an operating temperature range of -20 to +70 °C. The total extended body length is approximately 343 mm (body length A of 203 mm plus 140 mm stroke).

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X140TC Is Used
Material Handling & Lifting
The 6136 N push force at 0.5 MPa makes the SC125X140TC ideal for lifting heavy bins, tote dumpers, and pallet handling mechanisms in warehouses and distribution centres.
Agricultural Machinery
Use this cylinder on large seed drills, fertiliser spreaders, and bale-handling equipment where a robust pivoting actuator with a 140 mm stroke is needed for gate or chute control.
Heavy Press & Clamp Fixtures
Delivering up to 11045 N at 0.9 MPa, the SC125X140TC excels in weldment clamping, assembly presses, and heavy-duty holding fixtures requiring a centre-trunnion-mounted cylinder.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X140TC the Right Cylinder?
Choose the SC125 for heavy-duty pressing, clamping, and lifting tasks where the step-down SC100 (3927 N push at 0.5 MPa) would be marginal. If your application involves side loads or a stroke-to-rod ratio that risks bending, pair this cylinder with an external linear guide or switch to a guided cylinder—the 32 mm rod is robust but unsupported side forces can still cause premature bearing wear. For a correct replacement, match five points: 125 mm bore, 140 mm stroke, PT1/2 ports, centre trunnion (TC) mount with F-SC125TC bracket, and the absence of a 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 SC125X140TC FAQ
At 0.5 MPa the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa push rises to 8590 N, and at the maximum operating pressure of 0.9 MPa it reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. It is shorter in overall length and the mounting dimensions differ. Only replace another AirTAC SC (or equivalent tie-rod) cylinder of the same 125 mm bore, 140 mm stroke, PT1/2 ports, and centre trunnion mount.
