Cylindrical Roller shaft Category

- Aug 17, 2017 -

Cylindrical roller bearings belong to the separation type bearings, installation and disassembly is very convenient. Cylindrical roller bearings can withstand a larger radial load and are suitable for use in high speed operating situations.


This type of bearing allows for a small angle error (inclination) between the inner ring axis and the outer ring axis, only 2′~4′. Therefore, the machining accuracy of the shaft and housing is relatively high otherwise, it is easy to have uneven load or stress concentration in the raceway contact area. However, it can reduce the occurrence of stress concentration after correcting the roller or raceway contact bus.


Cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings According to the number of columns of the rolling body. The different structural bearings are also shown in the position design of the retaining edge. The commonly used cylindrical roller bearings have the following forms:

Single row cylindrical roller bearings: single row cylindrical roller bearings are separable bearings, easy to install and disassemble, two rings can be used tightly, the modified roller and raceway between the contact line can reduce stress concentration.


Double row Cylindrical roller bearing: Double row cylindrical roller bearing belongs to the traveling bearing, its separable nature makes installation and disassembly very convenient. Two rings can be used closely. Double row cylindrical roller bearings are hardly allowed to have angled corners.
