introduction：Single and double thrust ball bearing characteristics： Thrust ball bearings are designed to withstand thrust loads at high speeds,It consists of a gasket ring with a raceway groove for ball rolling。Because the ring is cushion shaped，therefore，Thrust ball bearings are divided into two types: flat base pad type and aligning spherical seat pad type。In addition，This bearing can withstand axial loads，But it cannot withstand radial loads。 1. Unidirectional with、Two types of two-way 2. In order to allow for installation errors，Whether its one-way or two-way，Can choose spherical aligning spherical seat cushion type or with spherical seat ring type。 3. High-quality steel ― The bearing life can be extended to the maximum80%The ultra-clean steel 4. High degree of grease technology ― NSKThe lubricant technology can extend the life of grease and improve the performance of bearings 5. High grade steel ball ― Quiet and smooth at high speeds 6. Use the ferrule in the option，Installation error is acceptable。

introduction：The design of double row angular contact ball bearings is basically the same as that of single row angular contact ball bearings，But it takes up less axial space。Double row angular contact ball bearings can withstand radial loads and axial loads acting in both directions，It can limit bidirectional axial displacement of the shaft or housing，The contact Angle is30The degree of。Bearing configurations with higher rigidity are available，And can withstand overturning moment。 Dust and rust are achieved by lubricating double row angular contact ball bearings。The bearing is preceded by two main grease lubrication methods and oil grease lubrication sealing type bearing grease filling and sealing method，Fill the inside of the housing with grease，In moderation，The filling method for each refill or replacement is fat。In addition，There are also many places to lubricate the machinery of double row angular contact ball bearings，But also use the pipe to connect the fat in a way that lubricates the local concentration。

introduction：FAGOuter spherical ball bearings are preferred for occasions requiring simple equipment and components，For example, it is used in agricultural machinery、Transportation systems or construction machinery。singleFAGThe outer spherical ball bearing unit consists of a double-sided sealed spherical outer ring deep groove ball bearing and a gray cast iron or stamped steel plate bearing seat。FAGThe outer spherical ball bearing series includes imperial and metric size bearings and their vertical and flanged housings（Part of the bearing seat size is somewhat different from the previous）。Most ofFAGExternal spherical ball bearings are fixed bearings so they are particularly suitable for supporting short shafts and for applications where little thermal expansion occurs。The small thermal expansion of the shaft can be compensated by the axial clearance of the bearing。 Bearings mounted on different bearing housings are163、362、562and762.2RSRSeries Deep groove ball bearings The first three series of bearings have a widened inn

introduction：Bearing technology and principle： Due to production process requirements，Some key equipment of industrial and mining enterprises operate under extremely harsh working conditions。Due to equipment weight、High ambient temperature，Large dust or acidic corrosive gas in the airCO，SO2Etc.，The lubrication of the equipment brings many problems，Severe friction and wear，So far，Most of the domestic enterprises still use traditional oil、Grease lubrication，And in fact these operating conditions are beyond the oil、Range of grease lubrication，It is very easy to be bitten or killed by bearings and other friction pairs，Cause serious wear and damage to parts，Frequently results in equipment outages。For continuous operation of production，In addition to the original design requires the installation of multiple equipment wheel repair，A large number of maintenance personnel are also required。Severely constraining productivity growth，Spare parts and energy consumption is great，Has become an important obstacle to the developmen

introduction：skfBearing damage analysis： To look for shaft bearing damage，Can be found in most cases，It can lead to them，Generally speaking，Only one third of the damage caused by fatigue damage of bearings comes from the occurrence of poor lubrication，And the other one-third of pollutants generated from the bearing or improperly handled installation。however，These injury types are not related to the industry bearings are precision parts，So it takes quite a long time to be cautious，Even with high-performance bearings，If used improperly，Nor can it achieve the expected performance effect，And easy to cause bearing damage。 therefore，The use of bearings should pay attention to the following points： first：holdskfBearings and their surroundings are clean，Even tiny invisible dust entering the bearing，Will increase bearing wear，Vibration and noise。 second：Use and install carefully，Let the powerful punch，It is not allowed to hit the bearing directly with the hammer and the pressure of activating the meridian is not allowed
