Here, the oil injection hole 28 and the connecting sliding groove 29 are provided to facilitate the user to inject lubricating oil into the annular connecting groove 23 through the connecting sliding groove 29 to open the oil injection channel before the bearing is used or when the lubricating grease is insufficient, so that the annular oil absorbing cotton 24 can fully absorb the oil, and provide sufficient oil reserve for subsequent self-lubrication, and ensure the continuous effectiveness of the self-lubrication system.
[0024] As shown in Figure 4 The inner surface of the connecting sliding groove 29 is connected with the sliding baffle 210, one end of the sliding baffle 210 is fixedly connected with the serpentine spring 211, and the other end of the serpentine spring 211 away from the sliding baffle 210 is fixedly connected with the inner wall of the connecting sliding groove 29.

[0025] As shown in Figure 1 The opposite surfaces of the outer ring 1 and the inner ring 2 are provided with annular sealing lips 4 on both sides, and the annular sealing lips 4 are provided with annular sealing lips 4 on both sides. Here, the annular sealing lips 4 preliminarily isolate the external environment from the bearing internal space, and preliminarily block dust, water stains and impurities, thereby providing basic sealing protection for the bearing interior.

[0028] The method for using the device and the working principle are as follows: during installation, the annular sealing lip 4 is sleeved on the outer convex ring frame 12 and the inner convex ring frame 22 through the annular grooves 41, so that the annular sealing lip 4 is closely attached between the outer ring 1 and the inner ring 2, the sealing structure installation of the bearing is completed, then the oil injection hole 28 is opened by compressing the serpentine spring 211 through the sliding baffle 210, lubricating oil is injected into the annular connecting groove 23, after the annular oil absorbing cotton 24 fully absorbs the oil, the sliding baffle 210 is loosened, and the sliding baffle 210 re-closes the oil injection hole 28 under the elastic action of the serpentine spring 211.
