ReplyDeleteFAG 33213 bearing
ReplyDeleteThe sealing structure is called double lip seal, which not only has the sealing advantages of the first structure, but also has the sealing advantages of the second structure, so the sealing effect is better. However, due to the limitations of current processing conditions and production costs, it is difficult for both lips to achieve an ideal contact and sealing state at the same time. Therefore, it is generally ensured that the radial direction has a better contact state, and the axial direction allows non-contact state. If you consider the sealing effect of the outer lip of the sealing ring, it can also be called a three-lip or multi-lip seal. Since this structure requires high processing precision of the sealing ring and the sealing groove of the ferrule, and the production cost is relatively high, it has not been widely adopted. With the continuous development of sealing ring and ferrule processing technology and the continuous improvement of processing quality, the multi-lip seal structure will be the development direction of bearing high sealing performance. For example, for the precision low-pitched automotive bearings produced by some domestic bearing manufacturers, the sealing groove is ground with a shaped grinding wheel, which greatly improves the processing accuracy of the sealing groove and the accuracy of matching with the sealing ring, so that the sealing performance of the bearing is improved. And the quality of vibration and noise has been significantly improved.
