[0008] The utility model has the following technical effects and advantages:

[0009] 1. Angular contact shaft collars and bearing rings can withstand a large amount of axial and radial loads. The bearing balls between them have high rigidity and wear resistance. Due to the radial rotation of the shaft column, the friction between the angular contact shaft collar and bearing ring is reduced, thereby reducing wear, increasing service life, and enabling them to maintain stable performance under high load conditions. They can withstand high-speed rotation and impact loads, ensuring the operational stability of the mechanical system.

[0010] 2. The spindle is equipped with angular contact collars and bearing rings of the same specifications at both the front and rear, and can be disassembled and assembled. It can be flexibly configured according to the usage requirements, and can be used alone or in pairs or groups to provide higher load-bearing capacity and rigidity. Attached Figure Description
