About the Airtac SC100 Standard Cylinder SC100X125CB
The SC100X125CB is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the 0.9 MPa maximum operating pressure. Its 125 mm stroke suits medium-travel clamping and positioning tasks, while the 25 mm diameter piston rod and 29 mm adjustable air cushion provide smooth end-of-stroke deceleration.
This model is configured with a CB rear double clevis (fork) mount, allowing the cylinder body to pivot during operation. The mounting accessory code is F-SC100CB. It uses standard PT ports (PT1/2), TPU seals for a -20 to +70 °C range, and has a body length A of 188 mm.

Where the Airtac SC100 Standard Cylinder SC100X125CB Is Used
Pivoting Bin Gate Actuation
The rear double clevis mount lets the cylinder swing with the gate linkage, providing the high push force needed to shear through bulk material in hoppers and silos.
Heavy Part Diverting
Delivers 3927 N at standard line pressure to reliably push heavy packages or pallets off a main conveyor onto a spur line, with the clevis absorbing any misalignment.
Welding Fixture Clamping
Applies up to 7068 N of clamping force at 0.9 MPa to hold large weldments securely. The adjustable cushion prevents impact vibration that could disturb the part alignment.
Is the Airtac SC100 Standard Cylinder SC100X125CB the Right Cylinder?
Choose the SC100 bore when your application needs roughly 3927 N at 0.5 MPa; if you can work with about 2513 N, stepping down to an SC80 reduces weight and air consumption. For strokes of 300 mm or more, evaluate side-load forces on the 25 mm rod and consider an external guide or guided cylinder to prevent rod bearing wear.
When replacing an existing cylinder, match five points: 100 mm bore, 125 mm stroke, PT1/2 port thread, CB rear double clevis mounting, and the absence of a magnet. This SC tie-rod cylinder is shorter than an ISO 15552 profile and is dimensionally interchangeable only with another AirTAC SC100 of the same 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 SC100X125CB 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, push force reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf (7850 N).
No. The SC100 is a double-acting cylinder and will not hold position if pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
