Description

Technical Field

[0001] This utility model belongs to the field of thrust ball bearing technology, and more specifically, it relates to a composite coated cage structure. Background Technology

[0002] Thrust ball bearings transmit force from the shaft ring to the housing ring, and then to the support structure. In this way, they bear and distribute axial loads, restrict the axial movement of the shaft, and ensure the axial positioning accuracy and stability of the shaft. The cage inside the thrust ball bearing separates the steel balls and guides their movement. Since the cage is in contact with the internal steel balls, lubrication is required to reduce friction between the steel balls. Lubricant needs to be added manually at regular intervals. Some bearings are installed inside machines, making disassembly and lubrication time-consuming and troublesome. Infrequent lubrication will affect the service life of the bearing.
