For motor manufacturers, one of the biggest headaches is that motors produced at substantial cost are returned by customers for rework right after delivery. This results in losses of materials and labor, as well as erosion of customer trust. |
"Newly off-line motors develop faults before being delivered to customers. After repeated checks, the root cause turns out to be the bearings!" This is a common trouble for the quality control departments of many motor manufacturers. Recently, during random inspection at a motor factory, hidden bearing risks were found in 15% of motors pending delivery. Traceability confirmed that all issues stemmed from careless details during assembly, namely that bearing failures originate from improper installation.
Many motor manufacturers attach importance to the quality of motor windings and iron cores, yet overlook bearing assembly details. Little do they know these details are key triggers of motor rework. Statistics show that 78% of motor bearing failures are not caused by quality defects of the bearings themselves.
In terms of physical principles, striking bearings with a hammer creates uneven internal stress, resulting in poor contact between balls and raceways. Pitting and cracks will occur after long-term operation. Fortunately, it is easy to avoid this risk: a dedicated press sleeve must be used during assembly, and any striking action is forbidden. Quality control allows no trivial negligence. The condition of bearings directly determines the pass rate of motors.
