About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550FA
The AirTAC SC160X550FA is a double-acting tie-rod cylinder with a 160 mm bore and 550 mm stroke, pre-assembled with a front rectangular flange (FA) for rigid panel mounting. At 0.5 MPa air pressure it generates 10053 N of push force, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa, placing it firmly in the heavy-duty industrial class.
This model uses a 40 mm diameter piston rod with an M36x2 male knuckle thread and PT3/4 port connections. The 29 mm adjustable air cushion at each end decelerates the high-inertia piston smoothly, while the standard TPU seals suit ambient temperatures from -20 to +70 °C. The FA front flange (accessory F-SC160FA) bolts directly to a machine face, keeping the cylinder body cantilevered for easy alignment.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550FA Is Used
Heavy Press Tool Actuation
Provides the high force (up to 18095 N) needed to operate clamping dies, punching tools, or forming presses in metal fabrication lines.
Bulk Material Gate Control
Drives heavy slide gates or diverter chutes in mining, aggregate, and agricultural bulk handling, where the front flange allows mounting inside tight head chutes.
Structural Test Rigs
Applies controlled linear force in material testing machines or structural load frames, where the rigid front-flange mounting resists reaction forces precisely.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550FA the Right Cylinder?
Choose the SC160X550FA when your application needs a front-flange mounting style that attaches the cylinder to a vertical surface from the rod end. If you require a pivoting mount, consider the rear clevis (CA or CB) or centre trunnion (TC) options instead. For a step down in force, the SC125 bore delivers 6136 N at 0.5 MPa; for higher force, the SC200 bore provides 15708 N.
At a 550 mm stroke, the 40 mm rod is robust, but any significant side load or off-axis force can cause rod bearing wear and bending. For applications where the load is not guided externally, add an external linear guide rail or switch to a guided cylinder to protect the rod and seals from premature failure. When replacing an existing cylinder, match the bore, stroke, PT port thread, FA front flange mounting, and the absence of a magnet exactly.
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 SC160X550FA FAQ
At 0.5 MPa (5 bar) air 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 reaches 18095 N. These values are based on the 160 mm bore and 40 mm rod diameter.
It can replace another AirTAC SC tie-rod cylinder or a compatible tie-rod design if five points match: 160 mm bore, 550 mm stroke, PT3/8 port thread, FA front flange mounting (F-SC160FA), and no built-in magnet. The SC is not dimensionally interchangeable with ISO 15552 profile cylinders.
