About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225S
The AirTAC SC125X225-S is a double-acting pneumatic cylinder with a 125 mm bore and 225 mm stroke, delivering a substantial 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 32 mm diameter piston rod and 28 mm adjustable air cushion are built to manage heavy linear loads with controlled end-of-stroke deceleration.
This model includes the -S suffix, equipping the cylinder with a built-in magnet. This allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the tie-rod barrel for reliable, non-contact position sensing. The SC125 is an ISO 6430 class tie-rod cylinder, designed for robust industrial applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225S Is Used
Pallet Conveyor Stops
The high force output at 0.5 MPa makes this cylinder ideal for stopping and releasing heavy pallets on gravity or powered conveyor lines, where a robust, sensor-confirmed position is critical.
Heavy-Duty Clamping
Used in welding fixtures or CNC machining centres to clamp large workpieces. The built-in magnet provides positive clamp/unclamp confirmation to the machine controller via DMSG sensors.
Baler & Compactor Actuation
Provides the linear thrust needed for compacting recyclable materials. The tie-rod construction and adjustable cushion withstand the high cycle rates and impact forces common in waste handling equipment.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225S the Right Cylinder?
For applications requiring less force, stepping down to an SC100 bore reduces push force to 3927 N at 0.5 MPa, while an SC160 bore steps up to 10053 N. This 225 mm stroke is well within the 1500 mm maximum standard stroke for the 125 bore. When replacing an existing unit, ensure a 5-point match: 125 mm bore, 225 mm stroke, PT port thread, basic mounting, and the -S magnet option for sensor compatibility.
At this stroke length, the 32 mm rod is robust, but any significant side loading should be managed with an external guide or a guided cylinder to prevent bending stress on the rod bearing and ensure long seal life.
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 SC125X225S FAQ
At the standard 0.5 MPa operating pressure, the theoretical 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 the model code SC125X225-S indicates a built-in magnet is installed in the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel to detect piston position without any additional brackets.
