About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X480
The SC125X480 is a double-acting pneumatic cylinder delivering substantial force for heavy-duty linear applications. Operating at 0.5 MPa, it provides a push force of 6136 N and a pull force of 5734 N, scaling up to a powerful 11045 N push at 0.9 MPa. This model features a 480 mm stroke, a 32 mm diameter piston rod with an M27x2 thread, and a 28 mm adjustable air cushion for smooth end-of-stroke deceleration.
With a body length A of 203 mm, the total extended length reaches approximately 683 mm. As part of the ISO 6430 class for large bores, this tie-rod cylinder is built for robust industrial use. The standard PT1/2 port and TPU seals suit a wide operating temperature range of -20 to +70 C. This is a genuine AirTAC SC series unit, engineered for reliable performance in demanding environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X480 Is Used
Heavy Press & Clamping
The 11045 N push force at 0.9 MPa makes the SC125X480 ideal for hydraulic-pneumatic press tools, heavy-duty clamping fixtures, and riveting stations where high force in a compact tie-rod format is essential.
Material Handling & Lifting
With 5734 N of pulling power, this cylinder can manage heavy lifting gates, large diverter chutes, or pallet stops on conveyor systems, providing reliable actuation for bulky or dense products.
Industrial Machinery Actuation
A core component in sawmill equipment, compactors, and large forming machines, the SC125X480 provides the sustained push-pull force needed for high-resistance process movements, benefiting from its adjustable cushion to handle heavy kinetic loads.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X480 the Right Cylinder?
Select the SC125 bore when your application requires force in the 6000-11000 N range at standard plant pressures. If your load is lighter, stepping down to an SC100 bore reduces air consumption while still providing 3927 N of push at 0.5 MPa. For higher force demands, an SC160 bore offers 10053 N at the same pressure. At a 480 mm stroke, the 32 mm rod is robust, but for any stroke over 300 mm, always check for potential side loading. If the load is not guided, consider adding an external guide rail to protect the rod bearing from bending moments.
For a direct replacement, ensure the new cylinder matches five key points: 125 mm bore, 480 mm stroke, PT1/2 port thread, the specific mounting accessory (this is a basic body mount), and the magnet option (this model has no built-in magnet). This SC series tie-rod cylinder is dimensionally shorter than a standard ISO 15552 profile cylinder and is not a drop-in replacement for one.
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 SC125X480 FAQ
At the standard operating pressure of 0.5 MPa, the SC125X480 produces a push force of 6136 N and a pull force of 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No, it is not a direct dimensional drop-in. The AirTAC SC series is a tie-rod cylinder that is shorter in overall body length than a comparable ISO 15552 profile cylinder. It is only a direct replacement for another AirTAC SC125 tie-rod cylinder with a 480 mm stroke, PT ports, and a basic mounting configuration.
