‌Why do seemingly robust motor bearings become the hidden culprit behind shortened air conditioner lifespan?

      Is it improper model selection or lubrication failure?

    A manufacturer of air conditioner compressor motors experienced a significant number of bearing failures during the warranty period, leading to customer complaints. They approached us seeking a solution to their bearing issues. After reviewing the case details, the home appliance manufacturer sent the faulty motors to us for analysis. Upon disassembling and inspecting the failed motors, we identified severe wear on both the inner and outer rings of the deep groove ball bearings. The raceway surfaces exhibited roughness and unevenness, and the lubricating grease inside the bearings had completely dried out and degraded.

  Our analysis revealed that the manufacturer prioritized production efficiency but compromised bearing installation quality during motor assembly, resulting in internal structural damage to the bearings. Additionally, the selected bearing grease exhibited poor thermal stability under high-temperature operating conditions, failing to meet long-term lubrication requirements.We provided the manufacturer with optimized ‌high-temperature resistant deep groove ball bearings‌ paired with ‌synthetic hydrocarbon grease‌.In addition, we guided the company to improve the bearing installation process. After the improvements, the average service life of the motor bearings was doubled, and feedback from the after-sales department indicated a significant reduction in customer complaints, with the company acknowledging our professionalism.
