About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450FA
The SC160X450FA is a robust double-acting pneumatic cylinder delivering a substantial push force of 10053 N at 0.5 MPa (up to 18095 N at 0.9 MPa), making it suitable for heavy-duty linear actuation tasks. This model features a 450 mm stroke with a 40 mm diameter piston rod and an adjustable air cushion (29 mm length) to decelerate the high-inertia load smoothly at the end of travel.
Configured with a front rectangular flange (mounting type FA, accessory F-SC160FA), this cylinder is designed for rigid panel or end-face mounting. The standard PT port thread is 3/4 inch, and the rod knuckle thread is M36x2. As a genuine AirTAC SC series tie-rod cylinder, it offers a compact, serviceable design for demanding industrial environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450FA Is Used
Heavy Press & Clamping
Provides the high force (up to 18095 N) needed for pneumatic presses, heavy-duty clamping fixtures, and riveting stations where a rigid front flange mount ensures precise alignment.
Material Forming
Ideal for bending, punching, or forming operations on sheet metal or composites, using the 450 mm stroke for deep draw or ejection actions with controlled cushioning.
Large Part Transfer
Moves heavy components or pallets between stations on a production line, with the front flange providing a stable mounting point on a machine frame or bulkhead.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450FA the Right Cylinder?
Select the SC160X450FA when your application requires a force class around 10000 N at standard plant pressure. For a step down in size, the SC125 bore provides 6136 N of push force at 0.5 MPa; for maximum force in this series, the SC200 bore delivers 15708 N. Always match the front flange mounting pattern and ensure your directional valve can handle the high flow rate required for a cylinder of this volume.
For this 450 mm stroke, be mindful of side loads. The 40 mm rod can experience bending stress if the load is not guided externally. For applications with significant lateral force, install an external guide rail system or consider a guided cylinder variant to protect the rod bearings and ensure long service life. For a direct replacement, match exactly: 160 mm bore, 450 mm stroke, PT port thread, front flange (FA) mount, and non-magnet 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 SC160X450FA FAQ
At the standard operating pressure of 0.5 MPa, 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 (20100 N).
It is a direct replacement only for another AirTAC SC or compatible tie-rod cylinder with the exact same bore (160 mm), stroke (450 mm), and front flange (FA) mounting. The mounting interface, port size (PT3/4), and rod thread (M36x2) must all match. The FA flange is integral to the front head, so the mounting dimensions must be verified against your machine's bolt pattern.
