Bearing dust cover is an important protective device used to protect the precision components inside bearings from dust, moisture, and other pollutants. This type of annular seal made of high-quality rubber or elastic material is usually precisely installed on bearing rings or washers, forming a precise labyrinth gap structure with mating components to effectively block external impurities.

Its unique rubber material not only has good sealing performance, but also adapts to temperature changes and mechanical vibrations under different working conditions. According to application requirements, dust covers can be divided into two designs: contact and non-contact. Contact covers use rubber sealing lips to directly contact the shaft, providing tighter protection; Non contact type achieves dust-proof effect through a sophisticated maze structure while reducing friction loss.
