Cylindrical roller bearings categories:

   Cylindrical roller bearings are separable bearings, installation and removal is very convenient. Cylindrical roller bearings can withstand greater radial load and high speed applications for use in lead.
     Stainless steel slewing bearing  the axis of the inner axis and the outer angle error (inclination) is small, only 2 'to 4'. Therefore, the shaft and housing is relatively high machining accuracy Otherwise, easy raceway contact area in uneven load or stress concentration. But roller or raceway contact busbar amendment could reduce stress concentration happening.
     Cylindrical roller bearings equipped with rolling under different number of columns, can be divided into single row, double row and multi-row cylindrical roller bearings and other different structures. Different structures bearing wall position is also reflected in the design. Which are commonly used cylindrical roller bearings have the following forms:
     Single row cylindrical roller bearings: single row cylindrical roller bearings are separable bearings, easy installation and removal, two rings can be a tight fit, fix the roller and raceway contact line between the stress concentration can be reduced.
     Double row cylindrical roller bearings: double row cylindrical roller bearings are swimming bearings, the separability makes installation and removal easy. Two rings are can be a tight fit. Double row cylindrical roller bearings almost not allowed inclination.
