Cylindrical bearings, ball bearings which durable, which is good, why?
This can not be generalized, depending on the specific working conditions. Cylindrical roller bearing ratio of deep groove ball bearings can withstand greater radial force, but its speed limit is not high also deep groove ball bearings, bearing the use of not only to consider the load, but also according to the specific structure to determine, for example is the need for axial fixation or axial swimming etc.. It is better to determine the bearing type according to the actual application requirements.
Roller bearings are usually guided by two blocks of a bearing ring. The cage, roller, and guide ring form a composite, generally separable bearing. The utility model has the advantages of convenient installation and disassembly, especially when the inner, outer ring and the shaft and the shell are in interference fit. Generally used only to bear radial load, only the inner and outer ring with single block bearings can bear less axial load or larger intermittent axial load. Compared with the deep groove ball bearings of the same size, this kind of bearing has larger radial load capacity, and is also suitable for high-speed rotation from the structure.
The use of the two bearings is different, the environment and place of use are also different.The ball bearing is mainly used in rolling friction, change the friction bearing, this way is more effective to reduce the friction between bearing surfaces, effectively enhance the fan bearing life, it will prolong the service life of the radiator. The drawback is that the process is more complex, leading to cost increases and higher work noise. Generally used in low load mechanical transmission equipment. Because of the ball bearing bearing area is small, prone to mechanical injury serious case in the high-speed operation, so the mechanical drive heavy load often take a needle bearing in order to increase the bearing surface, improve the mechanical transmission efficiency and reduce mechanical damage.
