About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200CB
The SC125X200CB is a heavy-duty double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa operating pressure. With a 125 mm bore and 200 mm stroke, this tie-rod cylinder uses a 32 mm piston rod with M27x2 male threads and features an adjustable air cushion length of 28 mm to decelerate end-of-stroke loads smoothly.
This specific model is configured with a rear double clevis (CB) mounting, part code F-SC125CB, allowing the cylinder to pivot during operation for articulated applications. It operates on filtered air from 0.15 to 1.0 MPa with standard PT ports and TPU seals rated for -20 to +70 °C. As an ISO 6430 class cylinder, it is built for robust industrial automation tasks requiring high force.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200CB Is Used
Heavy Machinery Articulation
The rear double clevis mount allows the cylinder to pivot, making it ideal for controlling the angle of bulldozer blades, excavator buckets, or agricultural tiller attachments where high force and angular movement are required.
Industrial Press Actuation
Generating over 11000 N of force at 0.9 MPa, this cylinder suits small to medium pneumatic presses for stamping, riveting, or compacting operations where a pivoting mount simplifies the mechanical linkage.
Material Handling Diverter Gates
Use the SC125X200CB to pivot heavy diverter gates or chutes in mining and aggregate processing. The double clevis provides stable, aligned pivoting under the high thrust needed to shift dense material flows.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200CB the Right Cylinder?
Select the SC125 when your application requires between roughly 6000 N and 11000 N of force. If your load is lighter, stepping down to an SC100 bore reduces push force to 3927 N at 0.5 MPa, saving energy and physical space. For strokes of 300 mm or longer, evaluate side-load conditions carefully—a 32 mm rod at full extension can experience bending moments under misaligned loads; consider adding an external guide rail or switching to a guided cylinder assembly.
To ensure a drop-in replacement, match five key points: bore (125 mm), stroke (200 mm), port thread (PT 1/2), the CB rear double clevis mounting, and the absence of a magnet sensor option. This model uses the standard TPU seals and PT threads; verify these match your existing machine’s plumbing and environmental requirements.
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 SC125X200CB 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, the push force reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No, the SC series is a tie-rod cylinder and is dimensionally shorter than a standard ISO 15552 cylinder, so it is not a direct drop-in replacement for ISO 15552 profile types. It is an exact match only for another AirTAC SC tie-rod cylinder or an equivalent tie-rod design sharing the same 125 mm bore, 200 mm stroke, PT port, and CB rear double clevis mount.
