About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000TC
The SC125X1000TC is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 125 mm bore and a 1000 mm stroke, this model features a 32 mm piston rod and an adjustable air cushion length of 28 mm to decelerate end-of-stroke impact.
This configuration includes a centre trunnion mount (TC), supplied with the TCM1 bracket for pivoting applications. The cylinder body length is 203 mm, resulting in a total extended length of approximately 1203 mm. As an ISO 6430 class tie-rod cylinder, it is built for robust industrial use with a speed range of 30-500 mm/s.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000TC Is Used
Heavy-Duty Clamping
The 11045 N force at 0.9 MPa securely clamps large weldments or castings in heavy machining and fabrication fixtures.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder to swing, making it suitable for actuating diverter gates on high-capacity conveyor systems.
Large Format Pressing
Delivers consistent, high-force linear motion for pressing bearings, bushings, or forming operations in assembly lines.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000TC the Right Cylinder?
Select the SC125 when your application requires a force class between the SC100 (3927 N at 0.5 MPa) and the SC160 (10053 N at 0.5 MPa). For this 1000 mm stroke, ensure the load is guided externally to prevent side-load bending on the 32 mm rod; long unsupported strokes are susceptible to rod bearing wear and seal damage. The TC centre trunnion allows the cylinder to pivot during operation, ideal for swinging loads.
For a direct replacement, match five key points: 125 mm bore, 1000 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC125TC bracket, and the standard TPU seal. This model does not include a magnet, so if sensor feedback is needed, specify the -S suffix.
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 SC125X1000TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N.
No. The SC series is a tie-rod cylinder and is physically shorter than an equivalent ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with matching bore, stroke, PT ports, and centre trunnion mount.
