About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X550S
The SC125X550S is a double-acting tie-rod cylinder with a 125 mm bore and 550 mm stroke, equipped with a built-in magnet for easy sensor mounting. It delivers a push force of 6136 N at 0.5 MPa and reaches 11045 N at the maximum operating pressure of 0.9 MPa, making it a powerful actuator for medium-to-heavy industrial tasks.
This model features a 32 mm piston rod with an M27x2 thread, PT1/2 ports, and a 28 mm adjustable air cushion at each end. The -S suffix denotes the integrated magnet, allowing CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for precise, non-contact position sensing. As an ISO 6430 class cylinder, it is built for robust, high-cycle applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X550S Is Used
Pallet Stop & Lift
The 6136 N push force at 0.5 MPa easily raises and stops heavy pallets on conveyor lines. The built-in magnet provides end-of-stroke confirmation to the PLC via a DMSG sensor.
Heavy Part Clamping
Use the 550 mm stroke to retract completely for part loading, then extend with up to 11045 N of force for secure clamping during welding or machining operations.
Bin Tilter & Dumper
The tie-rod construction handles the dynamic loads of tilting large bins. The -S magnet enables mid-stroke sensing for controlled deceleration before the adjustable cushion engages.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X550S the Right Cylinder?
Select the SC125 bore when your application requires a push force between 6136 N (at 0.5 MPa) and 11045 N (at 0.9 MPa). If your load is lower, stepping down to an SC100 bore reduces air consumption while still providing 3927 N at 0.5 MPa. For higher force demands, the SC160 bore offers 10053 N at the same pressure.
For this 550 mm stroke, carefully evaluate side-loading. Long, unsupported strokes on a single rod can create bending moments on the rod bearing. If your load is not guided, consider adding an external guide rail or switching to a guided cylinder to prevent premature seal and bearing wear. When replacing, match five critical points: 125 mm bore, 550 mm stroke, PT1/2 port thread, the built-in magnet (-S), and your required mounting accessory.
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 SC125X550S FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in SC125X550S indicates a built-in magnet is installed on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's tie-rod slots for reliable position feedback without additional brackets.
