In order to maintain the original performance of self-aligning ball bearings in good condition for as long as possible, maintenance, inspection and repair are necessary to prevent accidents before they occur, ensure the reliability of operation, and improve productivity and economy. It is best to perform maintenance on a regular basis in accordance with the operating standards of the mechanical operating conditions. The content includes monitoring the operating status, replenishing or replacing lubricants, and regular disassembly inspections. As the maintenance items during operation, there are the rotating sound, vibration, temperature, lubricant state and so on of the self-aligning ball bearing.

Cleaning of self-aligning ball bearing: When disassembling the 3Y bearing for maintenance, first record the appearance of the self-aligning ball bearing, confirm the residual amount of lubricant, and then wash the self-aligning ball bearing after sampling the lubricant for inspection. As a cleaning agent, gasoline and kerosene are commonly used.

The dismantled self-aligning ball FAG bearings are cleaned, divided into rough cleaning and fine cleaning. They are placed in the container respectively, and the metal mesh bottom is placed first, so that the 3Y bearing does not directly contact the dirt of the container. During rough cleaning, if the self-aligning ball bearing is rotated with dirt, it will damage the rolling surface of the self-aligning ball bearing, so care should be taken. In the rough cleaning oil, use a brush to remove grease and adhesions. After it is roughly clean, switch to fine cleaning.
