But we are here to say, was not working properly when the plastic bearing performance is below the requirements, known as the bearing damage or failure, bearing unforeseen circumstances the event of damage, etc., will stall its machinery, equipment , function subject to damage and other anomalies. Therefore investigated occurred in the short term, and take appropriate action, of course, the rolling bearing damage is much more complex than general mechanical parts damaged plastic bearing damage is characterized by manifestations more complex reasons, bearing damage in addition to bearing the design and manufacture of internal factors, mostly due to improper use, supporting the design is unreasonable, improper installation, poor lubrication, seal well external factors caused.
1, observed: bearing good lubrication and debris and moisture from entering the bearing oil seal wear, if the the original bearing box is opened, visually check the plastic bearings and regularly check the oil seal.
