About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210S
The SC125X210S is a double-acting tie-rod 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. Its 210 mm stroke suits medium-extension clamping, pressing, and material-handling tasks where high force is needed in a compact footprint. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for piston-position feedback.
This big-bore cylinder uses a 32 mm diameter piston rod with an M27x2 knuckle thread and PT1/2 ports. The adjustable air cushion (28 mm length) decelerates the piston quietly at end-of-stroke. With a body length A of 203 mm, the total extended length is approximately 413 mm. The SC125 is an ISO 6430 class cylinder, not an ISO 15552 profile, and is shorter than a comparable ISO 15552 unit.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210S Is Used
Heavy-Duty Clamping
Generates over 11000 N at 0.9 MPa for secure workpiece holding in machining centres and welding fixtures, with sensor confirmation via the built-in magnet.
Pallet Stop & Lift
The 210 mm stroke and 6136 N push force at 0.5 MPa reliably stops and lifts heavy pallets on conveyor lines, with position sensing for automated control.
Press & Forming Assist
Delivers consistent force for light pressing, riveting, or forming operations where a compact tie-rod design fits into tight machine frames.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210S the Right Cylinder?
Choose the SC125 when your application requires between 5000 and 11000 N of force at standard plant air pressures. If you need slightly less force, the SC100 bore provides 3927 N at 0.5 MPa; for more force, step up to the SC160 which delivers 10053 N at the same pressure. Always match bore, 210 mm stroke, PT port thread, and the -S magnet option when replacing an existing unit.
For this 210 mm stroke, the 32 mm rod provides good column strength, but sustained side loads should be managed with an external linear guide or a guided cylinder configuration to protect the rod bearing and piston seals from premature wear.
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 SC125X210S 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, push force reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet within the piston, making the cylinder compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp directly onto the tie-rod barrel.
