Why does Double row angular contact ball bearing have high load-bearing capacity?

In mechanical manufacturing and precision equipment, bearings are key components that connect and support moving parts. Their performance directly determines the stability and durability of the entire system. Among many bearing types, double row angular contact ball bearings have unique designs and Excellent performance, especially in high load-bearing capacity. 

The structural design of double row angular contact ball bearings is the basis for its high load-bearing capacity. This kind of bearing is supported by two rows of steel balls. Compared with the single-row design, its contact area is larger and the load is dispersed, thereby significantly improving the load-bearing capacity. At the same time, the contact angle between the ball and the raceway has also been carefully designed to effectively resist axial load while bearing radial load, further enhancing the bearing's load-bearing capacity. The material selection of double row angular contact ball bearings is also an important guarantee for their high load-bearing capacity. Bearings are usually made of high-strength, high-wear-resistant alloy steel. These materials have good mechanical properties and stability and can withstand larger loads. and impact. In addition, the inner and outer rings and rolling element surfaces of the bearing will be precision ground and polished to improve the smoothness and precision of the contact surface, reduce friction and wear, and extend the service life of the bearing. In addition to structural design and material selection, the preload adjustment of double row angular contact ball bearings is also a key factor in their high load-bearing capacity. Preload force refers to the adjustment of the relative positions of the inner and outer rings of the bearing during installation so that the rolling elements maintain a certain contact pressure when they are not affected by external forces. Appropriate preload can ensure that the bearing has good rigidity and stability when bearing load, and improve the bearing's load-bearing capacity and operating accuracy. The lubrication and maintenance of double row angular contact ball bearings are also important means to maintain their high load-bearing capacity. Through regular inspection and replacement of lubricating oil, cleaning of bearing surfaces and rolling elements and other maintenance measures, friction and wear can be effectively reduced and the load-bearing capacity of the bearings can be improved. and operational efficiency.
