About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400TC
The AirTAC SC160X400TC is a large-bore, double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 400 mm stroke, it is built for heavy linear actuation tasks where pivoting movement is required, thanks to the integrated centre trunnion mount.
The cylinder body measures 239 mm (dimension A) and features a 29 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly. This model is configured with the standard TPU seals for a working temperature range of -20 to +70 °C and PT ports, making it a robust solution for demanding industrial environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400TC Is Used
Heavy-Duty Clamping & Pressing
With a theoretical clamping force exceeding 2000 kgf, this cylinder is ideal for hydraulic-equivalent clamping in large welding fixtures, stamping press die cushions, and heavy assembly presses where high force and a pivoting mount are needed.
Agricultural & Construction Equipment
The robust tie-rod design and centre trunnion mount make it suitable for actuating chutes, hopper doors, and grader blades on heavy mobile equipment, handling high loads and dusty conditions reliably.
Large-Scale Material Handling
Deploy this cylinder to pivot and lift heavy dumpers, tilt large conveyor sections, or actuate heavy gates in bulk material handling systems, where its 18095 N push force at 0.9 MPa manages substantial off-centre loads.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400TC the Right Cylinder?
Select the SC160 bore when your application requires a push force between roughly 10053 N and 18095 N. If your force requirement is lower, stepping down to the SC125 bore provides 6136 N at 0.5 MPa; for even greater force, the SC200 bore offers 15708 N at the same pressure. This 400 mm stroke model includes the TC centre trunnion mount (part code F-SC160TC, supplied with the TCM1 bracket), which allows the cylinder to pivot during its stroke, essential for preventing rod bending in articulated linkages.
For a stroke of 400 mm, always check for potential side loads. The 40 mm rod is robust, but any off-axis force can cause bearing wear and seal failure. If side loading is unavoidable, use an external guide rail system to absorb the lateral forces and protect the cylinder. When replacing an existing unit, ensure a perfect match on all five critical points: 160 mm bore, 400 mm stroke, PT port thread, centre trunnion (TC) mounting, 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 SC160X400TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It must only replace another AirTAC SC160 tie-rod cylinder with matching bore, stroke, and centre trunnion (TC) mount. Only the 125-250 bore sizes conform to the ISO 6430 class standard.
