About the Airtac SC100 Standard Cylinder SC100X125N
The AirTAC SC100X125N is a double-acting tie-rod cylinder with a 100 mm bore and 125 mm stroke, fitted with NBR (nitrile) seals for reliable performance in standard industrial environments. This model delivers a push force of 3927 N at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa, placing it in a high-force class suitable for heavy clamping and pressing tasks.
With a 25 mm diameter piston rod and an M20x1.5 rod thread, the cylinder provides robust resistance to bending moments. The total body length is 188 mm, extending to 313 mm at full stroke. Its adjustable pneumatic cushion, with a 29 mm cushion length, effectively decelerates the piston to reduce end-of-stroke impact, ensuring smooth operation in demanding cycles.

Where the Airtac SC100 Standard Cylinder SC100X125N Is Used
Pallet Stop & Transfer
The 3927 N push force at 0.5 MPa allows this cylinder to reliably raise heavy pallet stops or actuate transfer arms in conveyor systems, handling substantial inertial loads.
Heavy-Duty Clamping
Ideal for welding jigs and assembly fixtures, the SC100X125N provides consistent, high clamping force to secure large workpieces during machining or fabrication processes.
Press-Fit Assembly
Delivers the controlled, high thrust needed for pressing bearings, bushings, or pins into housings, with the adjustable cushion protecting the assembly from impact damage.
Is the Airtac SC100 Standard Cylinder SC100X125N the Right Cylinder?
Select the SC100X125N when your application requires a force around 3900 N at standard plant pressure. If your load is lighter, stepping down to an 80 mm bore reduces the push force to 2513 N at 0.5 MPa, saving air consumption. For higher force requirements, the 125 mm bore provides 6136 N at the same pressure.
For this 125 mm stroke, the rod bearing is well-supported, but any side loading should be managed with an external guide. When replacing an existing cylinder, ensure a 5-point match: 100 mm bore, 125 mm stroke, PT port thread, NBR seal material, and the basic (no bracket) mounting configuration.
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 SC100 Standard Cylinder SC100X125N FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No, the 'N' suffix specifies NBR seals, which are rated for the standard temperature range of -20 to +70 °C. For high-temperature environments up to 150 °C, you should select the 'H' suffix variant (Viton seals), such as the SC100X125H.
