About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500FA
The SC125X500FA is a double-acting pneumatic cylinder delivering a substantial 6136 N of push force at 0.5 MPa, scaling up to 11045 N at the maximum operating pressure of 0.9 MPa. This model features a 500 mm stroke, a 32 mm diameter piston rod with M27x2 threads, and is equipped with an FA front rectangular flange for secure panel or bulkhead mounting.
With a body length of 203 mm and an adjustable air cushion of 28 mm, this ISO 6430 class tie-rod cylinder decelerates high-inertia loads smoothly at the end of stroke. Its PT1/2 ports and TPU seals suit standard compressed air systems operating between -20 and +70 °C, making it a robust workhorse for heavy linear motion tasks.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500FA Is Used
Heavy Press & Clamping
Generates up to 11045 N of force for pressing bearings, forming sheet metal, or clamping large workpieces in CNC machining fixtures.
Palletising & Material Handling
Provides the long 500 mm reach needed to push heavy pallets or transfer large components between conveyor lines in automated warehouses.
Damper & Gate Actuation
Operates heavy diverter gates or dampers in bulk material processing, using its front flange mount for stable, in-line force transmission.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500FA the Right Cylinder?
Select the SC125X500FA 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). The front flange (FA) mount, part F-SC125FA, rigidly supports the cylinder from the rod end, ideal for pushing loads through a panel. For strokes of 300 mm or more, like this 500 mm unit, ensure the rod is not subjected to lateral forces; use an external guide or a guided cylinder to prevent rod bending and premature bearing wear.
For a direct replacement, match these five points: 125 mm bore, 500 mm stroke, PT port thread, FA front flange mounting, and the absence of a magnet. This ensures dimensional and functional interchangeability with an existing AirTAC SC125X500FA unit.
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 SC125X500FA 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.
Yes, if the original unit is a genuine AirTAC SC125X500FA. Confirm the bore (125 mm), stroke (500 mm), PT port thread, FA front flange mount, and the absence of a magnet sensor option to guarantee a perfect dimensional and performance match.
