Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model is a heavy-duty bearing unit with a self-lubricating structure, including a bearing housing 1, a roller 3 connected to an inner bearing housing 9 on the inner side of the bearing housing 1, a ball 7 connected to the bearing housing 1 on the rear side of the inner bearing housing 9, a spacer 8 on the outer side of the ball 7, a first lubrication cavity 4 that fits against the roller 3 on the inner side of the bearing housing 1, a second lubrication cavity 12 that fits against the roller 3 on the inner side of the inner bearing housing 9, and load-bearing rings 15 on the outer sides of both the front and rear ends of the inner bearing housing 9.

[0020] In this embodiment, preferably, the inner side of the bearing housing 1 is provided with a first inner groove 2 that fits against the roller body 3, and the front end of the bearing housing 1 is provided with a first rubber plug 5 that engages with the first lubrication cavity 4.

[0021] In this embodiment, preferably, the rear end of the first lubrication cavity 4 is arranged in a ring and located inside the front end of the bearing housing 1, and the rear end of the first lubrication cavity 4 is provided with cavities that communicate with the outside of the roller body 3 at equal intervals.

[0022] In this embodiment, preferably, the ball 7 and the spacer block 8 are fitted together, and the inner sides of the left and right ends of the spacer block 8 are provided with grooves to accommodate the ball 7, which are used to limit the movement of the ball 7.

[0025] In summary, the inner side of the bearing housing 1 is provided with a first lubrication cavity 4 arranged in an annular shape, and the front end of the first lubrication cavity 4 extends to the front end of the bearing housing 1 and is engaged with the first rubber plug 5. When the roller 3 is installed in the roller groove 11 opened on the outer side of the bearing inner housing 9, the outer surface of the roller 3 can fit with the first inner sliding groove 2 opened at the inner end of the bearing housing 1. Then, the lubricant is injected into the inner side of the bearing housing 1 through the first lubrication cavity 4. The rear end of the first lubrication cavity 4 is arranged in an annular shape, and the inner side of the annular shape is provided with cavities that communicate with the first inner sliding groove 2 at equal intervals, so that the lubricant can directly contact the roller 3 to play a lubricating role.

Before use, the load-bearing ring 15 can be threadedly connected to the extension ring plate 14 by bolts 16, so that the bearing inner housing 9 and the load-bearing ring 15 form an independent unit. The inner side of the load-bearing ring 15 is provided with through holes 17 at equal intervals, which facilitates the use of construction screws to fasten the load-bearing ring 15 to the mounting surface when it is inserted through the through holes 17, thereby improving the adaptability of the combined unit.
