The shortcoming of roller bearings

There are always some problems in the daily usage and purchasing of imported bearing,toaday let the technician of sinda development give us a introduce the shortcoming of roller bearing,although the roller bearing has many advantages compared with the sliding bearing,is also has some shortcoming,mainly :

1.The vibration and noise of roller bearing is too big,and it is more obvious especially in the late period,so the roller bearing is not  competent for the situation which has high requirement to the precision .Difficult to do rolling bearings are generally chosen better sliding bearings.

2. Scrap of metal, such as rolling bearings are particularly sensitive to foreign body, foreign body bearing once, it will have a discontinuity to the larger vibration and noise, will cause early damage. In addition, the rolling bearing due to metal impurities, such as folder is also prone to early loss .The possibility of bad. Even if the damage does not occur early, the life of rolling bearings there are certain limits. In short, the life of rolling bearing shorter than the sliding bearing.

3. Rolling bearing load capacity to bear the same size than the sliding bearing is much less, therefore, the radial rolling bearing large size. Therefore, under heavy load in the radial size of occasions and requirements of small, compact structure of the occasion, more than the use of a sliding bearing.

However, the rolling bearing, compared with the sliding bearing, each with its own advantages and disadvantages apply to the possession of certain occasions, so the two can not fully replace each other, and their development to a certain degree of direction and expand the field of their own. However, due to roll highlight the advantages of fixed bearings, quite late on the trend of home. At present, the rolling bearing has become the main support for the mechanical type, the application of more and more widely.
Hope that the shortcomings of the technical staff of the introduction of rolling bearings can we use and purchase of FAG bearings to provide some help.
