The outer ring distributes the load evenly to the roller, which can increase the load-bearing capacity of the bearing, improve the bearing capacity and service life of the bearing. The bearing shell helps to reduce vibration and suppress the displacement of the bearing, thereby improving the running stability of the equipment. After the roller is embedded in the outer ring, it can provide a more stable structure and better fixation, which helps to reduce the vibration and displacement of the bearing during operation and improve the stability and running stability of the bearing. The retaining ring can prevent the free movement of the bearing in the axial direction caused by external force or other factors, ensuring that the bearing remains in the normal working position, which helps to improve the stability and running reliability of the equipment. By setting heat dissipation holes on the outside of the inner ring, the surface area contacting the outside air can be increased, and the heat dissipation efficiency of heat can be improved, thereby effectively reducing the temperature of the inner ring, which helps to prevent the bearing from overheating and improve the working efficiency and life of the bearing. The bearing with ceramic structure can reduce friction and wear, reduce energy loss, and extend the life of the bearing.

[0016] 2. By setting the fixings, support plates, plug-ins, inlays, grooves and bolt holes, when the power cord is inserted into the inner side of the support plate by using the fixings, and then the inlay of the plug-in and the support plate are fixedly connected by bolts, the power cord connector can be effectively prevented from falling off due to vibration caused by dragging or other external forces, which helps to maintain the stability and connection reliability of the power cord. The inlay of the plug-in is embedded in the groove of the support plate and fixed with bolts to ensure that the inlay will not fall off due to external force or vibration, which helps to maintain the stability of the inlay and avoid affecting the safety of the overall connection due to looseness of the inlay.
