A series of the bearing seal
Bearing seal can be divided into two types: bearing seal and external seal.The so-called bearing seal itself is to make the bearing itself into a sealing performance device.Such as bearing with dust cover, sealing ring, etc.The seal occupies little space, is easy to install and disassemble, and costs less.
The so - called bearing plus seal performance device, is in the installation of the end cover and other internal production of various performance of the sealing device.
The following main factors should be considered in the selection of bearing external seal:
1.Bearing lubricants and types (grease and lubricants);
2.The working environment of the bearing and the size of the space occupied;
3.Advantages of shaft supporting structure, allowing Angle deviation;
4.The circular velocity of the sealing surface;
5.Working temperature of bearing;
6. Manufacturing costs.
According to the requirement of bearing working condition and working environment to seal degree, it is often used in engineering design to achieve better sealing effect.
