Product Description

1. Cylindrical roller bearings . 

Cylindrical roller bearings are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.

The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring. 

There are different types designated as N, NU, NJ, NUP, NF (for single-row bearings like the following drawing); NNU, and NN (for double-row bearings depending on the design or absence of side ribs). 

1. Cylindrical roller bearings types . 

   In bearings of this type, 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 and inner rings of all types are separable.

   Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.

   Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.

   Depending on the existence of ribs on their rings, Cylindrical Roller Bearings are classified into the following types:

   Types NU, N, NNU, and NN are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings.

   NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars.

   The inner ring loose rib of an NUP-type cylindrical roller bearing should be mounted so that the marked side is on the outside.
