Classification Of Cylindrical Roller Bearings

Editor:Haining Wanlong Bearing Co.,Ltd │ Release Time:2015-11-24 

Cylindrical roller bearings are separable bearings, mounting and dismounting easy. Cylindrical roller bearings are able to withstand greater radial load applied in fast-moving situations. The bearings allows the angle of the axis of the inner ring and outer ring axis errors (tilt) is very small, only 2 ' ~4 '. 

Therefore, the relatively high Machining accuracy of shaft and housing or easily in Raceway contacts have uneven loads or stress. But the roller or Raceway contact bus was amended, can reduce the incidence of stress concentration. Of roller for cylindrical roller bearings according to the number of columns is different, can be divided into single row, double row and multi-row cylindrical roller bearing with different structures. 

Different bearing design is also reflected in the rib area. Cylindrical roller bearings are commonly used in several forms: single row cylindrical roller bearings: single row cylindrical roller bearings are separable bearings for easy installation and removal, two rings of can be a tight fit, correction roller line contact between the raceways and to reduce stress concentrations. 

Double row cylindrical roller bearings: double row cylindrical roller bearings are free bearing, its separateness makes installation and removal is easy. Both races are tight-fitting can be used. Double row cylindrical roller bearings are almost not allowed to tilt angle.
