The basic structure of the bearing inner ring with the NU -type cylindrical roller bearings the same , but because of the use of the needle , the volume can be reduced , and can withstand high radial load bearing without inner ring should have a suitable mounting surface accuracy and hardness of the shaft as raceway use .
Thrust needle roller bearings
Separated by a Precision bearing raceway ring and needle roller and cage components , (WS) can be used with any combination punching thin raceway ring (W) or processing of thick -cut raceway ring . Non-separable bearings are precision stamping by a raceway ring and needle roller and cage assemblies maintain overall bearing constituted . This class can withstand axial load bearing . Small footprint , compact design in favor of mechanical , they use only the needle roller and cage assemblies , and the Bearing test machine mounting surface of the shaft and housing to use as a raceway .
Tapered roller bearings with frustum -shaped roller , roller guided by the inner ring large rib . Designed to make the inner raceway, outer ring raceway and roller apex of the conical surface of the rolling surfaces intersect at a point bearing center line. Single row bearings can bear radial load and axial load, double row bearings can bear radial load and axial load , suitable to withstand heavy load and shock load.
Cylindrical roller bearings installed in accordance with the number of columns bearing rolling elements are different, cylindrical roller bearings can be divided into single row , double row and multi- row cylindrical roller bearings. Where the application is more cage single row cylindrical roller bearings. In addition, there are single or double row cylindrical roller filled and other structures roller bearings.
