Bearing seal: bearing p6 good or P5

Bearing in use after period of time, in many cases have the damage failure, which result in bearing damage factor is according to different damage degree and concluded that, through the understanding of the bearing use, summarizes some common in our daily damage of bearing fault, and for everybody in the form of pictures to show the bearing damage, and damage causes and corresponding solutions. To prevent hotbox, prevent aging oil itself, in order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. On the issue of the mechanical equipment noise, imbalance is due to the mechanical equipment operation, mechanical shaft concentricity deviation, the dimensional deviation between components or surface defects and the alternating mechanical force generated by the mutual collision and friction equipment sheet metal, bearings, gears and other moving parts vibration and radiation noise source called machinery noise. The use of the rolling bearing considerations for rolling bearing is high precision spare parts, and therefore a prudent attitude when use requirements accordingly, even when using the high performance bearing, if use undeserved, also cannot achieve the expected performance effect. After quenching process of bearing steel in small amounts not dissolve carbide helps to improve the wear-resisting degree of bearing, also helps to get fine grain cryptocrystalline martensite, so as to improve the bearing of toughness and fatigue strength; Carbide particle size influence on bearing life is very big also, carbide particles smaller than the bearing steel. 'N' outer rim, this kind of bearing installation, remove the more convenient, especially when the inner and outer ring and the shaft, when the shell is interference fit showed more advantages. The whole process is: the bar stock or tube ( Some bar need to the forging, annealing and normalizing) - - - - Car processing - - - - Heat treatment - - - - Grinding - - - - - lapping and polishing - - - Final inspection - parts - - - Rust - - - - Warehousing - - - - ( Machining process of steel ball. & emsp; & emsp; When the oil change, due to the lubricating oil mixed with hard grain impurity or bearing cleaning not clean with hard grain impurities, exacerbated bearing wear and overheating, and may even damage the insulation. Core parts of car is the engine is known to all the things, instead of rolling bearing? Below small make up together and discuss this problem! In the first place. But I don't see it completely from the exterior with Mercedes is there any connection between, just know it is a Mercedes and the product of famous brand watch swatch. External appearance can choose to install the new cars logo recognition, side window decoration article, disrupt the flow of the back board, discharge of tail gas pipe, into many functions such as gas grill. Such problems mainly because insulating paint volatilizes out acid formed under fixed temperature and humidity of corrosive substances, the bearing channel after corrosion result in bearing damage.
