Cylindrical roller bearing NSK Europe Ltd

NSK manufactures a complete range of cylindrical roller bearings. Both metric and inch sizes are available in bore sizes ranging from 1/2" to 1320 mm.
By virtue of the line contact between rolling elements and raceways, cylindrical roller bearings have high radial load capacity and are suited to high speed applications.

There are several designs, designated NU, NJ, NUP, N or NF for single row bearings and NNU or NN for double row types. In each case, the designation defines the bearing ring rib configuration.

For single row bearings NU and N types the inner and outer rings can move axially, in both directions, relative to one another. These are suited to use as ‘free-end’ bearings.

The other configurations are capable of sustaining axial loads. Double row bearings are used primarily in machine tool applications having high radial rigidity. Both NNU and NN configurations are ‘free-end’ types.

Pressed steel, machined brass and polyamide cages are available. Single row extra capacity designs can also be supplied.

For the steel industry NSK manufactures a range of four-row cylindrical roller bearings. These are primarily designed for use as steel mill roll-neck bearings.
