Product Description

Deep groove ball bearings are extremely common and widely used types of rolling bearings. The following will elaborate on their main content from aspects such as structure, characteristics, application scenarios, and maintenance: Structure Inner Ring: It is closely fitted and installed with the shaft. The inner diameter of the inner ring is precisely adapted to the shaft diameter to ensure a reliable connection. Its raceway surface is smooth, providing an accurate rolling track for the rolling elements and simultaneously bearing the radial force from the shaft and some possible axial forces. Outer Ring: Usually installed in the hole of the bearing seat or mechanical component, the outer diameter of the outer ring is precisely matched with the mounting hole. The outer ring raceway and the inner ring raceway work together to create a stable rolling environment for the rolling elements and transmit the load to the supporting structure. Rolling Elements: Generally, they are high-precision steel balls evenly distributed between the raceways of the inner and outer rings. When the bearing is in operation, the steel balls roll without slipping on the raceways of the inner and outer rings, enabling the relative rotational movement between the inner and outer rings and efficiently transmitting the load at the same time. Cage: Its function is to evenly separate the rolling elements to prevent collisions and friction between the steel balls and ensure that each rolling element is evenly stressed. Meanwhile, it guides the rolling elements to roll correctly in the raceways, enabling the bearing to operate smoothly and efficiently. Common cage materials include metals (such as stamped steel, brass, etc.) and non-metals (such as plastics).

Characteristics Advantages Low Friction Resistance: The rolling elements and raceways mainly have rolling friction. Compared with sliding friction, its friction coefficient is significantly reduced, resulting in less heat generation and low energy loss during operation, which can effectively improve the transmission efficiency of the mechanical system. High Limiting Speed: With a reasonable structural design and smooth movement of the rolling elements, deep groove ball bearings can maintain good stability and reliability at high rotational speeds and have a high limiting speed, which can meet the needs of many high-speed rotating equipment. Strong Versatility: It can withstand radial loads and a certain degree of axial loads and can be widely used in various types of mechanical transmission systems, such as in the fields of motors, automobiles, machine tools, household appliances, etc., adapting to different working conditions and load requirements. Low Noise: Under normal working conditions, deep groove ball bearings operate smoothly with a relatively low noise level, which helps to reduce the running noise of the entire mechanical equipment and improve the comfort of the working environment.
