About the Airtac SC100 Standard Cylinder SC100X550FB
The SC100X550FB is a double-acting pneumatic cylinder with a 100 mm bore and 550 mm stroke, equipped with an FB rear rectangular flange for secure end-face mounting. At 0.5 MPa it delivers 3927 N push force and 3681 N pull force, rising to 7068 N push at the 0.9 MPa maximum operating pressure, making it a strong actuator for medium-heavy industrial tasks.
This tie-rod cylinder uses a 25 mm diameter piston rod with M20x1.5 male threads and PT1/2 ports. The adjustable air cushion at each end (29 mm cushion length) decelerates the piston smoothly, while the TPU seals suit standard operating temperatures from -20 to +70 °C. The body length A is 188 mm, giving a total extended length of approximately 738 mm.

Where the Airtac SC100 Standard Cylinder SC100X550FB Is Used
Pallet Stop & Transfer
The 3927 N push force at 0.5 MPa and 550 mm stroke reliably raises heavy pallet stops or shifts loaded pallets between conveyor lanes in distribution centres.
Press-Frame Ejection
With 7068 N available at 0.9 MPa, this cylinder ejects formed metal or plastic parts from press tools, using the FB flange for rigid mounting on the press bed.
Damper & Gate Actuation
Operates heavy hopper gates or diverter flaps in bulk material handling. The adjustable cushion absorbs impact energy at the end of the 550 mm travel, reducing wear.
Is the Airtac SC100 Standard Cylinder SC100X550FB the Right Cylinder?
Select the SC100 bore when your application needs roughly 3900 N of push force at standard shop air; if you require around 6100 N, step up to the SC125 bore. For lighter tasks near 2500 N, the SC80 bore is a more compact alternative. The FB rear flange (accessory F-SC100FB) bolts directly to a machine frame or bulkhead, keeping the cylinder body rigidly aligned.
For this 550 mm stroke, side loads must be avoided. The 25 mm rod is robust, but long unsupported strokes can create a bending moment if the load is not guided. Use external linear guides or a rod-alignment coupler to protect the rod bearing and seal. When replacing, match bore, stroke, PT port thread, the FB rear flange mount, and the absence of a magnet to ensure identical fit and performance.
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 SC100X550FB FAQ
At 0.7 MPa (7 bar) the SC100 bore generates 5497 N of push force on the outstroke and 3681 N of pull force on the instroke (the pull force is calculated at 0.5 MPa in the datasheet thrust table).
Yes. The FB suffix specifies a rear rectangular flange (part F-SC100FB) that bolts to a vertical surface, supporting the cylinder from the cap end. Ensure the mounting surface can handle the full thrust reaction force.
