About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X45S
The AirTAC SC160X45S is a double-acting tie-rod cylinder delivering substantial force in a compact 45 mm stroke. At 0.5 MPa it generates 10053 N pushing and 9425 N pulling, while at the maximum operating pressure of 0.9 MPa the extending thrust reaches 18095 N.
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 contactless position sensing. The 40 mm diameter piston rod and PT3/4 port ensure robust flow for fast cycling, and the adjustable air cushion decelerates the 45 mm travel smoothly.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X45S Is Used
Heavy-Duty Pressing & Clamping
The 18095 N thrust at 0.9 MPa makes this cylinder suitable for hydraulic-replacement pressing, riveting, and heavy part clamping in assembly fixtures.
Automated Welding & Forming
The built-in magnet enables precise end-of-stroke confirmation via CMSG sensors, ensuring reliable clamping confirmation in automated welding cells and metal-forming presses.
Short-Stroke Material Stops
Use the SC160X45S as a high-force material stop or diverter on heavy-duty roller conveyors, where the short stroke rapidly lifts or retracts a stop plate.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X45S the Right Cylinder?
For applications needing slightly less force, the 125 mm bore SC series provides 6136 N push at 0.5 MPa. The SC160X45S is ideal where high force is needed in a short linear stroke, such as clamping or pressing. When replacing, match five points: 160 mm bore, 45 mm stroke, PT3/4 port thread, the built-in magnet (-S), and the basic mounting style (no integral bracket).
Even with a short 45 mm stroke, avoid applying direct side loads to the 40 mm rod; use an external guide or linear bearing if the tooling imposes lateral forces, as tie-rod cylinders are designed for axial thrust.
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 SC160X45S FAQ
At 0.7 MPa the SC160X45S delivers a pushing force of 14074 N. The maximum operating thrust at 0.9 MPa is 18095 N, and the theoretical force at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in SC160X45S indicates a built-in magnet inside the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be band-mounted on the barrel for non-contact position detection.
