1. Cylindrical roller bearings Description :

Cylindrical roller bearings belong to separable bearings, with easy method of mounting and dismounting. They can be classified into single row, double rows and four rows. As per different rib of the ring, single-row cylindrical roller bearings can be divided into N series, NU series, NF series, NUP series and so on. Cylindrical roller bearings carry a very heavy radial loads.

2. Types of Cylindrical roller bearings :

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.
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.

4. Application of Roller Bearing :

These bearings are mostly found in middle-sized and large-sized motors, electricity generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, unloading and lifting machines and other industrial machines.
