About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1120S
The AirTAC SC125X1120S is a double-acting single-rod pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 32 mm diameter piston rod and an M27x2 rod thread, this model is built for heavy linear actuation tasks requiring a long 1120 mm working stroke.
This ISO 6430 class cylinder features a built-in magnet (suffix -S), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback. The adjustable pneumatic cushion at each end (28 mm cushion length) decelerates the piston smoothly, protecting the end caps during high-speed operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1120S Is Used
Long-Stroke Material Pusher
The 1120 mm stroke and 11045 N peak force push heavy pallets or large components across wide conveyor transfer stations.
Automated Welding Fixture Clamp
Delivers consistent clamping force with sensor-confirmed position, ideal for holding large fabrications in robotic welding cells.
Sawmill Log Fence Positioner
Actuates a log fence or stop over a long travel distance, with the magnet sensor verifying retraction before the next log indexes.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1120S the Right Cylinder?
Select the SC125X1120S when your application requires a thrust around 6136 N at standard plant air pressure. If a lower force suffices, stepping down to the SC100 bore reduces push force to 3927 N at 0.5 MPa. For higher force requirements, the SC160 bore provides 10053 N at the same pressure. Always confirm the mounting style; this basic model has no brackets, so order the required accessory separately (e.g., foot mount F-SC125LB or flange F-SC125FA).
For this 1120 mm stroke, side-load management is critical. A long, unsupported 32 mm rod is susceptible to bending under lateral forces. Use an external linear guide or rod support to prevent rod bearing damage and ensure consistent cycling. For direct replacement, match the 125 mm bore, 1120 mm stroke, PT port thread, and the integrated magnet sensor feature.

- ✓ 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 SC125X1120S FAQ
At 0.7 MPa (7 bar) operating pressure, the theoretical push force is 8590 N. The maximum push force at 0.9 MPa is 11045 N.
Yes. The -S suffix indicates a built-in magnet in the piston, making it compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp onto the tie-rods.
