TECHNICAL FIELD

[0001] The utility model relates to bearing field, especially a kind of wear-resistant flange bearing. BACKGROUND

[0002] Flange bearing, also known as flange bearing, is a special design bearing, which is characterized by flange (or flange) on the outer ring or inner ring of the bearing. This design not only enhances the structural strength of the bearing, but also provides convenient installation and positioning function, making axial positioning simple and without bearing seat, more economical. Flange bearing is widely used in various industrial equipment, small rotary motor, office equipment and other fields, especially in high-speed rotation, low friction torque, low vibration, low noise occasions. It usually uses small diameter steel ball to ensure low friction torque, high rigidity and good rotation accuracy. At the same time, the design of hollow shaft ensures lightweight and wiring space. Flange bearing has the advantages of high load capacity, compact structure and high speed. Some flange bearings are usually provided with sealing ring for blocking dust from entering the inner ring and outer ring, so as to improve the service life of flange bearing. However, the traditional sealing ring is usually installed in contact with the bearing, so that the sealing ring will rotate and rub with the inner ring and outer ring during long-term use of the flange bearing, resulting in wear of the sealing ring, inner ring and outer ring, and finally reducing the service life of the flange bearing. Therefore, a wear-resistant flange bearing is needed to solve the above problems. SUMMARY
