ADVANTAGES
In terms of design, the N, NU, NN, NJ, NUP series differ mainly in the number of roller rows and the position of the inner / outer ring shoulders.
In some cases they can be proposed in the configuration with full complement cylindrical rollers (without cage) and are made in the configurations with one or two rows.
The absence of the cage allows for a greater number of rollers thus increasing the load capacity and stiffness.
