At present the utilised bearings can be categorized into rolling bearing and sliding bearing. As for their doing the job theory, persons can distinguish them from their names. When the rolling bearing is in procedure, the occurred friction is named rolling friction. When the sliding bearing is in procedure, the friction is recognised as sliding friction. The sum of the rolling friction is dependent on the bearing’s production precision. As for the total of the sliding friction, it has a shut marriage with the material of the bearing’s sliding area. the functioning surface area of the rolling bearing has the self-lubricating perform. According to the materials, the sliding bearing can be grouped into non-metallic sliding bearing and steel sliding bearing.
In the current market, the plastic bearing is the principal consultant in the non-metallic sliding bearing. In basic predicament the plastic bearing is produced by the engineering plastics with a fairly good assets. The specialist factories are typically excellent at the technologies these kinds of as self-lubricating technological innovation of the engineering plastics. By means of the fiber, exclusive lubrication, glass bead and so on the self-lubricating house can be improved. And then in use of the handled engineering plastics, the self-lubricating plastic bearing can be processed by the way of injection technology. At existing, the suppliers this sort of as IGUS in Germany, CSB in China are fairly outstanding in this area all around the earth.
Now the most common metal sliding bearing is 3-layer compound bearing. The carbon steel plate is the foundation plate of this bearing. Firstly, via Metal Processing & Manufacturing Services Supplier sintering know-how a layer of ball-formed copper powder will be sintered on the carbon steel plate. Then a layer of .03mm PTFE lubricant will be sintered on the layer of the copper powder. The functionality of the ball-shaped copper powder is to greatly enhance the bonding power between the carbon metal plate and PTFE. What is actually additional, in operation it can have the purpose of aid and lubrication. GGB corporation in the Usa, OILES corporation in Japan and CSB business in China are the professional makers.
From the over-pointed out introduction, it can be concluded that the Plastic Bearing and metal sliding bearing have the adhering to discrepancies. To begin with, the whole plastic bearing is the lubricating product and it has a lengthy operation everyday living. As for the metal sliding bearing, only the .003mm PTFE is the lubricating layer. When the slender layer is eradicated, the procedure lifetime of the bearing is around. Next, the plastic bearing is rust-proof and corrosion-proof. As for the steel bearing, it is effortless to rust and simply cannot be employed in the chemical liquid. Thirdly, compared with the metallic bearing, the price of the plastic bearing is lessen. Moreover, there is no sounds when the plastic bearing is in operation and this bearing has the function of vibration absorption.
