About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100
The SC125X100 is a double-acting pneumatic 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. With a 100 mm stroke and a robust 32 mm piston rod, this tie-rod cylinder is built for heavy linear actuation tasks where a compact retracted length is needed.
This model features a 28 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly. The body length A is 203 mm, giving a total extended length of approximately 303 mm. It uses standard PT1/2 ports and operates reliably in temperatures from -20 to +70 °C with its TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100 Is Used
Heavy-Duty Clamping
Generates over 11000 N of force at 0.9 MPa for securely holding large workpieces during machining or welding operations.
Material Lift & Transfer
Provides the high push force needed to lift or transfer heavy pallets and components in a short, 100 mm linear stroke.
Press-Fit Assembly
Delivers controlled, high-force linear motion for pressing bearings, bushings, or pins into housings on automated assembly lines.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100 the Right Cylinder?
Choose the SC125 bore when your application requires between 6136 N (SC125) and 3927 N (SC100) of push force at 0.5 MPa. If your load is lighter, stepping down to the SC100 bore can reduce air consumption and physical size. For strokes of 300 mm or longer, evaluate side-load forces on the 32 mm rod and consider an external guide or a guided cylinder to prevent rod bearing damage.
To ensure a correct replacement, match five key points: bore (125 mm), stroke (100 mm), port thread (PT1/2), mounting accessory (basic, no bracket), and the presence of a magnet (this model has none). The SC series is a tie-rod design and is dimensionally shorter than an ISO 15552 cylinder, so it is not a direct drop-in replacement for that standard.
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 SC125X100 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 increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder and its body length is shorter than a standard ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. It should only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port, and mounting specifications.
