[0008] As a further improvement, the outer edge of the protective outer ring may preferably protrude downward and wrap around a portion of the side wall connected to the outer ring.

[0009] As an improvement, an annular limiting groove may preferably be provided on the outer surface of the shaping inner ring, and the inner ring of the elastic inner ring is embedded in the limiting groove.

[0010] As an improvement, an annular limiting groove may preferably be provided on the inner hole wall of the pressure-resistant outer ring, and the molded outer ring is embedded in the limiting groove of the pressure-resistant outer ring.

[0011] As an improvement, the inner ring groove may preferably be an arc-shaped groove arranged circumferentially.

[0012] As a further improvement, the arc-shaped groove may preferably be a through groove that radially penetrates the shaped inner ring.

[0013] As a further improvement, the arc groove may preferably be a thin groove located in the axial middle of the shaping inner ring, and there are two arc grooves, which are symmetrically arranged.

[0014] Compared with the prior art, the utility model has the following advantages: the inner ring includes a shaped inner ring made of metal and an elastic inner ring made of TPU material, the shaped inner ring is inserted into the elastic inner ring, the elastic inner ring has good pressure resistance and wear resistance, has good buffering effect on the radial force and axial force applied to the bearing, and improves the service life of the bearing; the shaped inner ring is provided with an inner ring groove for accommodating lubricating oil to improve the lubrication effect. The outer ring is sleeved on the outer wall of the elastic inner ring, and a pressure-resistant outer ring is provided on the outer surface of the outer ring, which further increases the pressure resistance of the bearing and extends the service life of the bearing.
