About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800TC
The SC125X800TC is a heavy-duty 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 an 800 mm stroke and a robust 32 mm piston rod, this model is built for large-scale industrial automation tasks requiring high force over a long travel distance.
This configuration includes a centre trunnion mount (TC), supplied with the TCM1 bracket (F-SC125TC), allowing the cylinder to pivot and accommodate angular movement during operation. The adjustable air cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact, protecting the cylinder and the machine structure.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800TC Is Used
Heavy Material Handling
Pivoting transfer stations on large conveyor lines use the trunnion-mounted SC125X800TC to divert heavy pallets or bulky goods with a powerful, controlled 800 mm stroke.
Large Component Clamping
Delivering up to 11045 N of force, this cylinder provides the high clamping pressure needed to secure large weldments or castings in heavy fabrication jigs.
Agricultural Equipment Actuation
The robust tie-rod construction and centre trunnion mount suit the demanding, dusty environment of farm machinery, such as actuating chutes or gates on large harvesters.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800TC the Right Cylinder?
This 125 mm bore model is ideal when the 100 mm bore's 3927 N force at 0.5 MPa is insufficient. If your application requires even higher force, stepping up to the 160 mm bore provides 10053 N at the same pressure. For this 800 mm stroke, side-load management is critical; the long, unsupported 32 mm rod is susceptible to bending under lateral forces. Always use an external guide rail or rod-alignment coupler to protect the rod bearing and seals.
When replacing an existing cylinder, ensure a precise 5-point match: 125 mm bore, 800 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and no magnet. This SC series is a tie-rod design, shorter than an ISO 15552 cylinder, so dimensional interchangeability is limited to another AirTAC SC125 of the same configuration.
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 SC125X800TC FAQ
At the standard operating pressure of 0.5 MPa, the push force is 6136 N. At 0.7 MPa it increases to 8590 N, and at the maximum operating pressure of 0.9 MPa it reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes, the TC centre trunnion mount (supplied with TCM1 bracket) is specifically designed for pivoting applications. However, with an 800 mm stroke, you must ensure the load is guided externally and does not impose side loads on the rod, as the long extension makes the 32 mm rod vulnerable to bending damage.
