Cylindrical roller bearings

The cylindrical roller bearings are bearings capable of enduring high radial loads. This typology has high resistance to rapid and high accelerations thanks to the line contact between the rollers and the rolling tracks.

Both the outer rings like the inner ones can be detached to facilitate assembly or disassembly, mounting with interference is also possible.


Standard Fersa cylindrical bearings are single row. Depending on its internal design, there are 4 product families (N, NJ, NU, NUP) able to detach the inner or outer ring depending on the type.

Depending on the design type, the rollers operate guided between the flanges of the outer and/or inner rings.
