[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 - Figure 4 As shown, the utility model provides the following technical solutions: a curved roller, comprising: a cylinder 1, a double-row deep groove ball bearing 3 is installed inside the cylinder 1, a sealing component for sealing the double-row deep groove ball bearing 3 and a movable component for realizing the rolling of the roller are installed on the surface of the double-row deep groove ball bearing 3, the movable component is connected to the shaft body inside the cylinder 1 through a bracket structure, and the sealing component is installed inside the cylinder 1.

[0020] Through the above technical solution:

[0021] When in use, under the condition of constant outer diameter and inner diameter, the double row deep groove ball bearing 3 has a larger width and a load capacity much higher than that of ordinary deep groove ball bearings. In addition to bearing radial loads, the double row deep groove ball bearing 3 can also bear axial loads acting in two directions. At the same time, the double row deep groove ball bearing 3 large clearance roller special cage has the advantages of light weight, low noise, wear resistance, anti-magnetic, low friction, and reduces the friction between the cage and the rolling element to effectively extend the service life of the bearing.

[0022] Furthermore, the sealing assembly includes a sealing gasket 5 and a labyrinth seal 6. The sealing gasket 5 is arranged on one side of the bearing along the axial direction of the roller, and the labyrinth seal 6 is arranged on the other side of the double-row deep groove ball bearing 3 along the axial direction of the roller.

[0023] Specifically, the labyrinth seal 6 is formed by injection molding of polypropylene, ABS or nylon, and grease is filled between the labyrinth seals 6. At the same time, in order to prevent the sound of the double-row deep groove ball bearing 3 from being transmitted through the roller shaft, amplitude reduction sleeves are designed at both ends of the shaft using the characteristics of the labyrinth seal 6 to reduce the amplitude of the sound of the double-row deep groove ball bearing 3 and block the transmission of the sound.

[0024] Furthermore, a bearing seat 2 is installed inside the cylinder 1 , and a bearing reinforcement sleeve 4 is also provided between the sealing gasket 5 and the double-row deep groove ball bearing 3 and between the bearing seat 2 and the double-row deep groove ball bearing 3 .

[0025] Specifically, the bearing seat 2 of the non-metallic roller is formed by injection molding of polypropylene, ABS or nylon material. In particular, when non-metallic materials are used, the bottom of the bearing seat 2 is set to a honeycomb shape to make the roller run smoothly and with low noise, and the bearing reinforcement sleeve 4 is formed by injection molding of nylon resin or polytetrafluoroethylene.
