[0028] The lubricating oil groove 200 is provided with the lubricating oil hole 300, and the lubricating oil hole 300 is connected to the radial inner side of the main body 100.

[0029] This open-type steel-backed bearing uses high-strength spring steel, which greatly improves its load-bearing capacity, making it 2 to 3 times higher than that of ordinary steel. By defining the structure of the opening 101 on the main body 100, its asymmetrical structure about the axis of the main body 100 makes the load borne by the bearing more uniform in all directions, thereby improving the service life of the bearing. In addition, the opening 101 on the main body 100 can deform to a certain extent during installation, reducing the positioning accuracy requirements of the shaft hole during installation and facilitating adjustment.

Furthermore, the center of the lubricating oil hole 300 is set opposite to the connection between the first part 102 and the second part 103.

[0033] Furthermore, the main body 100 has chamfers on the radially outer sides of both sides in the axial direction, and the lubricating oil groove 200 has chamfers on the radially outer sides of the inner walls on both sides in the axial direction. The beveled surface of the chamfer can avoid stress concentration caused by sharp corners, thereby further improving the strength and durability of the main body 100, while reducing material costs.

[0034] In one embodiment, the thickness of the spring steel plate is approximately 3 mm to 5 mm;

[0035] The width of the lubricating oil groove 200 is 15mm to 20mm;
