Embodiment Construction
[0036] It can be seen from the background art that a bearing sealing device with a dust-proof ring has good sealing performance. However, the sealing device has strict requirements on the dust-proof ring, which must be made of corrosion-resistant metal materials. During the operation of the bearing, the contact part of the sealing device and the dust-proof ring will have sliding contact, so the dust-proof ring needs to meet a relatively low roughness, and the requirement for the dimensional accuracy of the dust-proof ring is also high. Therefore, the manufacturing cost of the sealing device is high.
[0037] In order to reduce the cost of the sealing device, the embodiment of the present invention provides a bearing and a sealing device. The technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, The described embodiments are only some, ...
