About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000S
The AirTAC SC125X1000S is a double-acting single-rod tie-rod cylinder delivering 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 125 mm bore and a 1000 mm stroke, this model is built for heavy linear automation tasks that require substantial force over a long travel distance.
This unit includes the factory-installed -S magnet, enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for reliable end-of-stroke or mid-stroke position feedback. The 32 mm diameter piston rod, PT1/2 ports, and 28 mm adjustable air cushion at each end ensure robust performance and controlled deceleration. As an ISO 6430 class cylinder, it is rated for speeds of 30-500 mm/s.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000S Is Used
Palletizing & Heavy Lifting
The 6136 N push force at 0.5 MPa and 1000 mm stroke make this cylinder ideal for palletizing stations, lifting heavy bins, or raising large workpieces in material handling cells.
Large Component Clamping
Use the SC125X1000S for clamping large weldments or engine blocks in heavy fabrication fixtures. The built-in magnet provides sensor confirmation that the part is securely clamped before a cycle starts.
Press & Forming Assist
Deploy this cylinder as a material pusher or ejector in thermoforming and composite presses. The adjustable cushion absorbs kinetic energy from the heavy moving mass, protecting the tooling at stroke end.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000S the Right Cylinder?
Choose the SC125 bore when your application needs the 6136 N push force at 0.5 MPa; if you can work with 3927 N, stepping down to the SC100 bore reduces air consumption and physical size. For this 1000 mm stroke, ensure the rod is protected from side loads—use an external linear guide or a guided cylinder configuration, as the long unsupported 32 mm rod is susceptible to bending under lateral forces.
When replacing an existing cylinder, match these five points exactly: 125 mm bore, 1000 mm stroke, PT1/2 port thread, the built-in magnet (-S), and your required mounting accessory (this model is basic, but you can add an F-SC125LB foot mount or F-SC125TC centre trunnion).
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 SC125X1000S FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, specifically designed for direct mounting of AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors on the barrel tie-rods. This provides contactless, reliable position sensing without external flags.
