This type of bearing allows for a very small angle error (inclination) between the inner ring axis and the outer ring axis, only 2 'to 4'. Therefore, the machining accuracy of the shaft and bearing seat is relatively high. Otherwise, uneven load or stress concentration may occur at the contact area of the raceway. However, correcting the contact busbar of the roller or raceway can reduce the occurrence of stress concentration.

Cylindrical roller bearings can be divided into different structures such as single row, double row, and multi row cylindrical roller bearings based on the number of rows of rolling elements installed. Different structural bearings are also reflected in the design of the position of the retaining edge. The commonly used cylindrical roller bearings have the following forms:

Single row cylindrical roller bearing: Single row cylindrical roller bearing is a separable bearing that is easy to install and disassemble. Both rings can adopt a tight fit, and the modified contact line between the roller and raceway can reduce stress concentration.
