About the Airtac SC100 Standard Cylinder SC100X520SFB
The SC100X520SFB is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (up to 7068 N at 0.9 MPa). Its 100 mm bore and 520 mm stroke suit medium-to-heavy linear actuation tasks where a rear flange mount (FB) is preferred for rigid end-face attachment.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The 25 mm diameter piston rod and 29 mm adjustable air cushion provide robust guidance and smooth end-of-stroke deceleration. Total extended body length is approximately 708 mm (body length A=188 mm + stroke).

Where the Airtac SC100 Standard Cylinder SC100X520SFB Is Used
Conveyor Diverters
The 520 mm stroke and 3927 N push force at 0.5 MPa reliably shift heavy packages or pallets onto branch conveyors, with the rear flange mount securing the cylinder to a fixed end plate.
Press-Fit Assembly
Delivers up to 7068 N at 0.9 MPa for pressing bearings or bushings into housings. The built-in magnet sensor confirms full extension and retraction for automated cycle control.
Material Lift Gates
Controls a vertical lift gate with a 520 mm travel. The adjustable air cushion decelerates the 25 mm rod smoothly at stroke end, preventing shock loads on the gate structure.
Is the Airtac SC100 Standard Cylinder SC100X520SFB the Right Cylinder?
Choose the SC100 bore when your application requires roughly 3900 N of force at standard shop air (0.5 MPa). If your load is lighter (around 2500 N), stepping down to an SC80 (2513 N at 0.5 MPa) can reduce air consumption and physical size. For higher force, the SC125 delivers 6136 N at 0.5 MPa.
At 520 mm stroke, ensure the rod is not subjected to significant side load; long unsupported strokes on a 25 mm rod can experience bending stress. Use an external linear guide or a guided cylinder if the load is not purely axial. For exact drop-in replacement, match bore (100 mm), stroke (520 mm), PT port thread, FB rear flange mount (F-SC100FB), and the -S magnet option.
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 SC100X520SFB FAQ
At 0.5 MPa, the cylinder pushes with 3927 N and pulls with 3681 N. At the maximum operating pressure of 0.9 MPa, push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC series is a tie-rod cylinder and is shorter than a standard ISO 15552 cylinder, so dimensions and mounting interfaces are not interchangeable. Only use it to replace another AirTAC SC100 tie-rod cylinder with matching bore, stroke, PT port, FB rear flange, and magnet option.
