The two ends of the newly developed rolling bearing are equipped with corresponding sealing devices. Its role is, on the one hand, to keep the grease (oil) inside the bearing in use will not be lost, to ensure that the bearing is in a lubricate state, on the other hand, to protect the dust or harmful gas outside the bearing will not enter the bearing cavity, in order to prevent damage to the bearing. Common rubber or engineering plastic sealing ring, there are also steel plate punching sealing ring (or dust cover). The sealing structure of the sealing ring is varied, and the sealing effect is not the same. There is a gap between the sealing ring and the rotating shaft, called non-contact seal, the smaller the gap, the better the sealing effect, but the shaft speed is allowed to be smaller; The opposite is true. There is no gap between the sealing ring and the rotating shaft, called contact seal, the larger the contact area of the sealing ring contact lip, the better the sealing effect, but the smaller the speed of the shaft is allowed, on the contrary. The main research content of sealing technology is to research and develop the corresponding sealing device applied in different working conditions, as well as the compatibility of the sealing ring material and the corresponding grease.
