Fersa basically markets single row cylinder roller bearings in its metric versions (NU, NJ, NUP and N), in addition to a range of bearings full of rollers and with special uses.
Fersa can also supply this type of bearing with an elastic ring incorporated into it, which is a simple way to offer axial fastening in their applications.
Single row roller bearings are usually manufactured with a normal radial set, unless specified otherwise.
They have great capacity to endure radial loads, operate at high speeds and absorb impact loads.
A summary of their Operating Characteristics can be seen in the following outline:
