The ABEC (Annular Bearing Engineering Committee) rating system was established by the American Bearing Manufacturers Association to standardize the production and evaluation of bearings, making it easier for consumers to understand and compare bearings of different grades. However, the ABEC rating is not universally applicable to all applications, particularly when it comes to electric bicycles.
Rigorous control of bearing tolerances is a crucial element in ensuring the stable operation of mechanical equipment. Abnormal noise during bearing operation may result from vibrations, metal collisions, or rattling sounds. Failure to address bearing tolerance and abnormal noise issues properly can lead to mechanical damage, posing a risk to the overall productivity of the company.
