Structural composition of thrust roller bearings

‌1. Raceway ring: The raceway ring of a thrust roller bearing is used to support axial force. The raceway ring assembled to the shaft side is called the shaft ring, while the raceway ring assembled to the housing side is called the seat ring.

‌2. Rolling element: The rolling element is the core component of a thrust roller bearing and is usually assembled as a whole by an iron or copper cage. The common form of rolling elements is steel balls, which are specially designed to withstand axial forces.

‌3. Cage: The function of the cage is to prevent adjacent rolling elements from contacting each other and to ensure that a certain distance is maintained between the rolling elements so that the rolling elements can roll smoothly.
