Deep groove ball bearings with filling slots structural features of filling slots

Deep Groove Ball Bearings with Filling Slots is a type of bearing widely used in multiple industrial fields. Its unique filling slot structural design provides significant advantages for bearing lubrication and performance optimization. During the operation of bearings, the distribution and supply of lubricating oil are crucial to reducing friction, reducing wear, and extending bearing life. The filling slot design of Deep Groove Ball Bearings with Filling Slots was born to meet this demand. Through carefully designed filling grooves, the bearing can store and distribute lubricating oil more effectively during operation, thereby ensuring that the bearing can still maintain good lubrication status under high speed, high temperature or heavy load conditions.

The filling groove is usually located in a specific position of the cage, and its shape is usually long or arc-shaped to facilitate the storage and distribution of lubricating oil. The layout of the filling grooves is optimized and designed according to the specifications and usage conditions of the bearing to ensure that the lubricating oil can be evenly distributed to various key parts of the bearing.
The size and number of filling grooves are key factors that affect its performance. Generally speaking, the depth and width of filling grooves should be appropriately adjusted according to the diameter and rotation speed of the bearing. The number of filling grooves should also be adjusted according to the bearing capacity and usage conditions of the bearing. Properly configured, too many filling grooves may cause uneven distribution of lubricant, while too few filling grooves may not meet the lubrication needs of the bearing. The material of the filling groove should be the same or similar to that of the cage to ensure its high strength and wear resistance. In order to further improve the lubrication performance of the filling groove, its surface can also be specially treated, such as polishing, coating, etc.

During the operation of the bearing, lubricating oil will be continuously sucked in and discharged through the filling groove. When the bearing speed is low, the lubricating oil is mainly sucked in and kept in the groove through the capillary action of the filling groove; when the bearing speed is high, The centrifugal force causes the lubricating oil to be thrown out of the filling groove and evenly distributed to various key parts of the bearing. This working mechanism allows the bearings to maintain good lubrication conditions even when running at high speeds, thereby effectively reducing friction and wear.

Through the design of the filling groove, the bearing can continue to be replenished with lubricating oil during operation, thereby maintaining a low friction coefficient and temperature rise. The good lubrication state enables the bearing to withstand greater radial and axial loads, improving the Its load-bearing capacity and service life are significantly improved because the bearing's lubrication performance is significantly improved, so its wear and failure rate are also reduced accordingly, thereby reducing maintenance costs and usage risks.
