NJ NU N NF Series Cylindrical Roller Bearings

When it comes to Cylindrical Roller Bearings, the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.

There are different types designated as NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs). The outer rings and inner rings of all types are separable.

Some cylindrical roller bearings have no ribs on either the inner ring or outer ring so the rings can move axially relative to each other.

Our Cylindrical Roller Bearings are available in a wide range of designs, series, variants and sizes. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials.
