About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200S
The AirTAC SC125X200S is a double-acting tie-rod cylinder delivering a substantial push force of 6136 N at 0.5 MPa (max operating thrust 11045 N at 0.9 MPa). Its 200 mm stroke is well within the 1500 mm maximum standard stroke for this 125 mm bore, ensuring standard lead times. The built-in magnet (-S suffix) allows direct mounting of CMSG/DMSG/EMSG sensors on the barrel for contactless position detection.
This ISO 6430 class cylinder features a robust 32 mm piston rod with M27x2 thread and PT1/2 ports. The adjustable pneumatic cushion (28 mm length) decelerates the piston smoothly, protecting end caps. Operating on filtered air from 0.15 to 1.0 MPa, it handles temperatures from -20 to +70 C with its standard TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200S Is Used
Heavy Part Transfer
Pushes or lifts heavy components on conveyor lines with 6136 N of force at standard shop air pressure.
Press-Fit Assembly
Delivers up to 11045 N of thrust for pressing bearings, bushings, or pins into housings with controlled, cushioned motion.
Material Handling Gates
Actuates large diverter gates or chutes for bulk materials, with magnetic sensors confirming open/closed states.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200S 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 under ~4000 N, stepping down to the SC100 bore (3927 N at 0.5 MPa) can reduce air consumption and physical size. For loads above 11045 N, consider the SC160 bore.
For this 200 mm stroke, side-loading is a manageable risk, but always align the rod with the load path. The 32 mm rod has good rigidity, but an external guide or linear bearing is recommended if any lateral force is present. When replacing, match five points: 125 mm bore, 200 mm stroke, PT1/2 ports, the basic mounting style, and the built-in magnet for sensor compatibility.
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 SC125X200S 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 at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in SC125X200S indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the barrel for reliable, non-contact position sensing.
