About the Airtac SC100 Standard Cylinder SC100X300FB
The SC100X300FB is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 300 mm stroke. At 0.5 MPa it generates 3927 N pushing force and 3681 N pulling force, placing it in a high-force class suitable for pressing, clamping, and lifting medium-to-heavy tooling. The 25 mm diameter chrome-plated piston rod and 29 mm adjustable air cushion at each end provide robust guidance and smooth deceleration.
This model is configured with an FB rear rectangular flange (accessory F-SC100FB), allowing rigid end-face mounting to a machine frame or panel. The standard PT1/2 port threads and TPU seals suit filtered-air systems operating from -20 to +70 °C. With a body length A of 188 mm, the total extended length is approximately 488 mm, making it a compact power package for its force class.

Where the Airtac SC100 Standard Cylinder SC100X300FB Is Used
Pallet Stop & Lift
Raises or stops heavy pallets on conveyor lines. The 3927 N push force at 0.5 MPa easily lifts a loaded pallet, while the rear flange mount bolts securely to the conveyor frame.
Press-Fit Assembly
Provides the controlled, high-force linear motion needed to press bearings, bushings, or dowels into housings. The adjustable cushion protects the assembly from impact damage at the end of the 300 mm stroke.
Heavy Clamping Fixture
Acts as the power element in a welding or machining fixture. The 3681 N pull force securely clamps large workpieces, and the FB flange allows direct mounting to the fixture base plate.
Is the Airtac SC100 Standard Cylinder SC100X300FB the Right Cylinder?
Choose the SC100X300FB when your application needs roughly 4000 N of push force at standard plant pressure. If your load is lighter and you want a smaller, faster cylinder, step down to the SC80 bore (2513 N push at 0.5 MPa). For a significant force increase without raising pressure, step up to the SC125 bore (6136 N push at 0.5 MPa). This 300 mm stroke is within the standard range for the 100 mm bore, but always check for side loads: a 300 mm extended rod can experience bending stress. If side force is present, use an external guide or switch to a guided cylinder. For direct replacement, match bore, stroke, PT port thread, FB rear flange mount, and the absence of a magnet.
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 SC100X300FB FAQ
At 0.5 MPa the theoretical push force is 3927 N. At 0.7 MPa it rises to 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf. Always apply a safety factor for dynamic loads.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC100 cylinder with the same bore, stroke, PT port, and FB rear flange mount.
