About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X710TC
The AirTAC SC125X710TC is a double-acting tie-rod 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, 32 mm piston rod, and a 710 mm stroke, this model is built for heavy linear actuation tasks. The centre trunnion (TC) mount, supplied with the TCM1 bracket, allows the cylinder to pivot during operation, accommodating swinging loads.
This cylinder features adjustable pneumatic cushioning at both ends (28 mm cushion length) to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 203 mm, resulting in a total extended length of approximately 913 mm. Ports are PT1/2 with an M27x2 rod thread. As an ISO 6430 class cylinder, its speed range is 30-500 mm/s. The operating temperature range for this TPU-sealed unit is -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X710TC Is Used
Heavy Press & Clamping
Generates over 11 kN of force at 0.9 MPa for powerful clamping, pressing, and riveting operations in metal fabrication and assembly lines.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder to swing, making it ideal for actuating diverter gates or sorting paddles on large conveyor systems.
Agricultural Machinery
Provides the robust force and long 710 mm stroke needed for controlling chutes, hopper doors, and linkages on harvesters and heavy-duty farming equipment.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X710TC the Right Cylinder?
For applications requiring less force, stepping down to a 100 mm bore reduces push force to 3927 N at 0.5 MPa. If a higher force is needed, the 160 mm bore provides 10053 N at the same pressure. This 710 mm stroke is well within the 1500 mm maximum standard stroke for the 125 mm bore. When specifying a replacement, match these five points: 125 mm bore, 710 mm stroke, PT1/2 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the absence of a built-in magnet.
With a stroke of 710 mm, side loads on the 32 mm rod must be managed carefully to prevent bending or premature bearing wear. For applications where the rod must support a transverse load, use an external linear guide or a guided cylinder to ensure the rod moves purely axially.
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 SC125X710TC 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.
Verify the five key compatibility points: 125 mm bore, 710 mm stroke, PT1/2 ports, centre trunnion (TC) mount with the matching TCM1 bracket (part code F-SC125TC), and no magnet. The SC is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a direct drop-in replacement for that standard.
