"Inflatable Air Blower" is generally used on top of the radiator dispersed varieties: use of sliding friction sleeve bearings and use a rolling friction ball bearings and two types of bearings mix of these three forms. Over the years many manufacturers introduced a lot of new terms in bearing technology, such as magnetic bearings, water bearing, bearing core, "Inflatable Air Blower" are also on top of the basic forms of bearings made to improve the operation of the principle did not change . Ordinary air-cooled radiator oil bearings and ball bearings are mainly used. Dual ball bearing high-end products, high-precision, high-quality, high prices, high product belonging to three. Oil bearing satisfy various working conditions, but "Inflatable Air Blower" life cycle is very long, the price is relatively low, but the quality, relatively speaking, more general.
