About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X120
The SC160X120 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 160 mm bore with a 120 mm stroke. At 0.5 MPa it generates 10053 N of push force, placing it firmly in the heavy-duty industrial class for pressing, clamping, and lifting applications.
This model features a 40 mm diameter piston rod with M36x2 threads and PT3/4 ports. The adjustable air cushion (29 mm length) decelerates the piston smoothly at each end, protecting the end caps. The body length A is 239 mm, giving a total extended length of approximately 359 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X120 Is Used
Heavy Press Frames
The 10053 N push force at 0.5 MPa makes this cylinder ideal for assembly presses, riveting stations, and stamping fixtures requiring consistent, high-force linear motion.
Pallet Lifting & Tilting
With its robust 40 mm rod and tie-rod construction, the SC160X120 reliably handles the high cycle demands of lifting and tilting heavy pallets in material handling systems.
Clamping Large Workpieces
Use this cylinder for secure clamping of large fabrications or castings during machining. The adjustable cushion prevents vibration and impact damage to the fixture.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X120 the Right Cylinder?
Choose the SC160X120 when your application needs roughly 10 kN of force at standard plant pressure. If you need less force, stepping down to the SC125 bore reduces push force to 6136 N at 0.5 MPa. For higher force requirements, the SC200 bore delivers 15708 N at the same pressure.
For this 120 mm stroke, side loading is typically not a concern if the rod is aligned axially. However, always avoid direct lateral forces on the rod. When replacing an existing cylinder, match all five key points: 160 mm bore, 120 mm stroke, PT3/4 port thread, basic (no bracket) mounting, and no 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 SC160X120 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.
This specific model (SC160X120) does not include a built-in magnet. To use reed or solid-state sensors (CMSG/DMSG/EMSG) for position detection, you need the -S suffix variant (SC160X120-S), which has a magnet integrated into the piston.
