About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180S
The SC125X180S is a double-acting pneumatic cylinder delivering 6136 N push force at 0.5 MPa, suitable for medium-to-heavy linear actuation tasks. Its 180 mm stroke, combined with a 32 mm diameter piston rod and 28 mm adjustable air cushion, provides controlled deceleration in a compact tie-rod body with a body length of 203 mm.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. Operating on filtered air from 0.15-1.0 MPa and -20 to +70 °C with standard TPU seals, it offers a speed range of 30-500 mm/s in the ISO 6430 class large-bore format.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180S Is Used
Heavy Part Clamping
The 6136 N push force at 0.5 MPa securely clamps large weldments or castings in machining fixtures, with the 180 mm stroke providing ample clearance for part loading.
Pallet Stop & Divert
Integrates into heavy-duty conveyor lines as a pallet stop or diverter. The built-in magnet enables end-of-stroke sensing to confirm gate position before releasing the next load.
Forming Press Assist
Delivers up to 11045 N at 0.9 MPa for pressing, bending, or forming operations on sheet metal or composite materials, with adjustable cushioning to reduce cycle-end shock.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180S the Right Cylinder?
For higher force, step up to the SC160 (10053 N push at 0.5 MPa); for a lighter, faster option, the SC100 provides 3927 N. This 125 mm bore cylinder uses PT1/2 ports and an M27x2 rod thread. To ensure a correct replacement, match bore, stroke, PT port thread, the basic mounting configuration, and the integrated magnet (-S) for sensor compatibility.
At 180 mm stroke, the rod is well-supported within standard limits, but any side load should be managed with an external linear guide 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 SC125X180S FAQ
At 0.5 MPa the cylinder pushes with 6136 N and pulls with 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical force at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in the model code SC125X180S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel's tie-rod slots for position feedback.
