About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X220S
The AirTAC SC125X220S is a double-acting single-rod tie-rod cylinder delivering 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 32 mm diameter piston rod and PT1/2 ports suit medium-to-heavy pneumatic tasks where consistent linear thrust is required over a 220 mm stroke.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The adjustable air cushion (28 mm length) decelerates the piston at stroke ends, reducing impact and noise in high-cycle applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X220S Is Used
Material Transfer Gates
The 6136 N push force at 0.5 MPa and sensor-ready magnet make this cylinder ideal for actuating diverter gates on wide conveyor lines, where end-of-stroke confirmation is required for interlocking.
Heavy Part Clamping
With 11045 N of force available at 0.9 MPa, the SC125X220S provides robust clamping for welding fixtures or machining centres. The built-in magnet enables clamp-open and clamp-closed sensor verification.
Press & Forming Assist
Use this cylinder for stripping or ejection strokes in medium-tonnage forming tools. The adjustable cushion absorbs energy from the 220 mm stroke, protecting tooling from shock at cycle rates up to 500 mm/s.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X220S the Right Cylinder?
The SC125 bore sits between the SC100 (3927 N push at 0.5 MPa) and the SC160 (10053 N push at 0.5 MPa). If your load requires more than 6136 N at 0.5 MPa, step up to the SC160; for a lighter, more compact installation, the SC100 may suffice. For strokes over 300 mm, consider external guides or a guided cylinder to protect the rod bearing from side-load bending moments.
When replacing an existing cylinder, match five points: 125 mm bore, 220 mm stroke, PT1/2 port thread, the basic mounting configuration (no bracket), and the built-in magnet (-S) for sensor compatibility. This SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125X220S 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, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in SC125X220S indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be mounted directly on the barrel tie-rods for precise, non-contact position sensing.
