Yes, self-aligning ball bearings require regular maintenance. Regular maintenance is crucial for extending bearing life and ensuring stable equipment operation. The maintenance frequency needs to be determined based on equipment operating conditions and operating time. Routine maintenance mainly includes the following: First, regularly check the bearing's operating condition, observe for abnormal noise or vibration during equipment operation, and check the bearing temperature. If the temperature is too high or the noise is abnormal, stop the machine immediately for inspection and troubleshooting. Second, regularly replenish or replace grease or lubricating oil. Depending on the equipment's operating time and conditions, replenish grease every 3-6 months and replace lubricating oil every 6-12 months to ensure the bearing is always in good lubrication condition. Third, regularly clean dust and debris around the bearing and check the sealing condition of the seals. If the seals are damaged, replace them promptly to prevent impurities from entering the bearing. Fourth, regularly check the bearing's wear condition. If wear, scratches, or corrosion are found on the steel balls or raceways, replace the bearing immediately to avoid damaging the equipment.
