About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X950S
The SC160X950S is a large-bore, double-acting AirTAC tie-rod cylinder delivering a substantial push force of 10053 N at 0.5 MPa (18095 N at the maximum operating pressure of 0.9 MPa). With a 40 mm diameter piston rod and a 950 mm stroke, it is built for heavy industrial linear actuation tasks that require significant power over a long travel distance.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for reliable, non-contact position feedback. The adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly at the end of the stroke, protecting the end caps from impact. The body length A is 239 mm, resulting in a total extended length of approximately 1189 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X950S Is Used
Heavy Press & Clamping
The 10053 N push force at 0.5 MPa makes this cylinder ideal for powering heavy-duty shop presses, die-casting clamping units, and large assembly fixtures requiring high, consistent force.
Palletizer & Conveyor Pushers
With a 950 mm stroke, it can push heavy pallets or large packages across wide conveyor transfer stations, providing the long travel and force needed for automated material handling.
Industrial Gate & Damper Actuation
The long stroke and robust 40 mm rod are suited for opening and closing large hopper gates, ventilation dampers, or diverter chutes in mining, agriculture, and processing plants.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X950S the Right Cylinder?
For applications needing slightly less force, consider stepping down to a 125 mm bore SC125 series, which provides 6136 N of push force at 0.5 MPa. If your load demands exceed the 10053 N at 0.5 MPa, the 200 mm bore SC200 series offers 15708 N. For this 950 mm stroke, ensure the rod is protected from significant side loads; long, unsupported strokes on a single rod can create a bending moment. Use an external linear guide or a guided cylinder to absorb lateral forces and prevent premature rod bearing and seal wear. When replacing, match five key points: 160 mm bore, 950 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style.
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 SC160X950S FAQ
At the standard 0.5 MPa operating pressure, the push force is 10053 N and the pull force is 9425 N. The maximum push force at 0.9 MPa is 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in the model code SC160X950S designates a built-in magnet. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor groove to detect piston position without additional brackets.
