introduction：Section bearings are classified according to different methods，According to the direction or nominal contact Angle of the load can be borne，It is divided into centripetal joint bearing and thrust joint bearing。 1、Radial joint bearings are used to bear radial loads，Its nominal contact Angle is from0Go to45The degree of，According to their nominal contact Angle，Can be divided into：Radial contact radial joint bearing nominal contact Angle is0Degree of centripetal joint bearing，Suitable for radial loads。

introduction：It is very important to lubricate linear bearings，And also know the important role of grease in the use of bearings。"A client asked，Is it possible to use unlimited grease to lubricate the bearing？This is not allowed，Because of the excessive use of grease，Is a lot of harm to linear bearings。 Grease has good adhesion、Abrasion resistance、Temperature tolerance、Rust resistance and lubricity，Can improve high temperature oxidation resistance，Delay aging，It can dissolve carbon deposits，Prevent the accumulation of metal debris and oil，Improve the wear resistance of the machinery、Pressure and corrosion resistance。

introduction：superheating frominaThe microstructure overheating after quenching can be seen on the rough edges of imported bearing parts。However, it is necessary to examine the microstructure to determine the level of superheat。ifGCr15Coarse acicular martensite appears in the quenched structure of the steel，It is quenched superheated tissue。The reason may be that the quenching heating temperature is too high or the heating and holding time is too long；It may also be due to the severe carbide in the original tissue，The low carbon region between the two zones is composed of martensitic acicular thickness，The formed parts overheat。The residual austenite in superheated tissue increases，Dimensional stability drop。Overheating of the tissue due to quenching，The crystal of steel is thick，It will cause the toughness of the parts to fall，The impact resistance is reduced，Bearing life is also reduced。Overheating is so severe that a quenching crack may form。

introduction：Bearing housing is very prone to wear，If the wear is serious，That affects the service life，For such a bearing seat we can not normally use，As long as timely repair can continue to use，Otherwise, its a waste.。But there are a lot of people who dont understand the repair steps of the bearing seat so that we cant repair it，Lets take a look at it。

introduction：Here is a brief introduction to the composition of ceramic bearings，General ceramic bearings are made of ceramic silicon oxide，Ceramic calcium oxide compared to traditional bearing surface will be very smooth，More uniform size，All can better reduce friction main force，Reduces the energy required to turn the bearing，So it can highlight the advantages of ceramic bearings，Advantage in transformation，The energy required to convert the wheel is also about 30 percent higher than that of conventional bearings，And ceramic bearings are a better advantage in one aspect of wear resistance。
