1. The rolling bearing has been standardized, serialized and generalized, which is suitable for mass production and supply, and is very convenient for use and maintenance
2. The internal clearance of rolling bearing is small, and the machining precision of each part is high, so the operation precision is high.At the same time, the bearing rigidity can be increased by preloading.This is very important for precision machinery
3. SUNTHAI [/ url] rolling bearings can be easily applied to uranium in any direction in space
4. Since some rolling bearings can bear both radial and axial loads, the structure of the SUNTHAI [/ url] bearing bearings can be simplified
5. Because of the high transmission efficiency of rolling bearing, less heat, therefore, can reduce the consumption of lubricating oil, lubrication maintenance is relatively easy
6. The friction coefficient of rolling bearing is smaller than that of sliding bearing, and the transmission efficiency is high.The friction coefficient of general SUNTHAI [/ url] sliding bearing is 0.08-0.12, while that of rolling bearing is only 0.001-0.005
7. The rolling bearing is made of bearing steel and has undergone heat treatment. Therefore, the rolling bearing not only has high mechanical properties and long service life, but also can save the relatively expensive non-ferrous metals used in the manufacture of sliding bearings
Although rolling bearing has many advantages compared with sliding bearing, it also has some disadvantages, mainly as follows:
1. The vibration and noise of rolling bearing are relatively large, especially in the later period of use, which is particularly significant. Therefore, it is difficult for rolling bearing to be suitable for the occasion with high precision requirements and no vibration
2. SUNTHAI [/ url] rolling bearing is especially sensitive to metal chips and other foreign bodies. Once foreign bodies enter the bearing, it will produce large vibration and noise intermittently, which will also cause early damage.In addition, the rolling bearing is also prone to early damage due to metal inclusions.Even if does not occur early damage, the rolling bearing life also has certain limits.In short, the life of rolling bearings is shorter than that of sliding bearings
3. The load bearing capacity of the rolling bearing is much smaller than that of the samtae SUNTHAI [/ url] sliding bearing of the same volume. Therefore, the radial dimension of the samtae SUNTHAI [/ url] rolling bearing is larger.Therefore, in the case of bearing large load and the requirements of small radial size, compact structure requirements, most of the use of plain bearings
