About Cylindrical Roller Bearing:
1.Cylindrical roller bearings are separable bearings, installation and removal is very convenient.
2.Cylindrical roller bearings can withstand greater radial load, suitable for use in high speed applications.
3.Cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings and other different structures.
4.Cylindrical roller bearings can be divided into PO, P6, P5, P4, P2 according to accuracy class.
Cylindrical roller bearing 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 NU, NJ, NUP, N, NF for single-row bearings,and NNU, NN for double-row bearings depending on the design or absence of side ribs.
