What is the difference between bearing factory bearing and metal bearing?

What is the difference between bearing factory bearing and metal bearing? What is the difference between bearing factory bearing and metal bearing? Material in different use bearing products divided into classes and metals, while in the actual work of the function is the same, but after all is two different kinds of bearing products, it is not hard to see is a big difference. Everyone can be differentiated from the following aspects: 1, the quality obviously must be lighter than the weight of the metal, thus made the bearing is dominant in terms of quality, more can satisfy the requirement of lightweight product design; 2, general bearing is using the way of injection molding processing, simple process is very suitable for mass production; After casting bearing metal needed a series of process, complexity make metal bearing can't meet the requirement of mass production; 3, bearing performance even under the harsh environment use, will not be influenced by environmental factors, such as rust, corrosion bad phenomenon; The metal bearing can't guarantee in this respect, because the metal is easy to react with acid, alkali, etc, to rust; 4, the service life of the performance is excellent, and its overall are made of lubricating material, makes the bearing has a long service life; And on the surface of the metal bearing lubrication material once after friction, life will be affected.
