[0002] The slewing bearing seat is a large and extra-large bearing seat that can accept combined loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, convenient installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the so-called bearing seat.

[0003] For example, the Chinese authorized patent with the publication number CN220748832U (a sealing member for a bearing seat): includes a sealing ring. One end of the sealing ring extends outward to form a positioning cylinder. The positioning cylinder is coaxially arranged with the sealing ring and has the same inner diameter. The outer diameter of the positioning cylinder is smaller than the outer diameter of the sealing ring. An annular cavity coaxial with it is arranged inside the sealing ring. The cross-section of the annular cavity is circular. The inner diameter of the annular cavity is larger than the outer diameter of the positioning cylinder. At the positions where both ends of the sealing ring pass through the annular cavity, they bulge outward to form an annular arc convex surface. This sealing member improves the sealing performance of the bearing seat when applied to the bearing seat.

[0004] However, most of the existing bearing seats are sealed in the middle and lack sealing at both ends. The lubricating oil is easy to leak from both sides, causing pollution and waste. Therefore, it does not meet the existing requirements. For this reason, we propose a sealing member for a bearing seat. Content of the Utility Model
