introduction：1、When the linear bearing is loaded into the shell，If there are oil holes in the bearing，Should be aimed with the oil hole on the housing。 2、Setup time,In particular, the bearing and the housing hole should be carefully coaxial．For this at the time of installation，Just accept the guide mandrel。 3、The compression method is accepted according to size and interference volume、Heating method or cold loading method，Insert bearing into housing hole。 4、Linear bearing hole correction：The inner bore of the bearing will tighten after loading into the housing，It is usually necessary to increase the bearing bore size,bearing(Copper part)Increase the size of the inner hole。After the bearing is loaded，A proper gap can also be arranged between the inner hole and the journal。Also in the manufacture of bearings．The amount of fine hinge left in the inner hole，After bearing device,Refine reaming，Its common clearance is guaranteed。Fine reaming time，Guide the reamer very carefully，Otherwise, it will cause the deflection of the axi

introduction：Rolling bearings if not selected incorrectly，If used correctly，Before the service life out of the inlet，It can be used for a long time。On the other hand，And unexpected premature damage，And can not withstand the early damage of use，As the cause of this early injury，There is not enough consideration on the use of scare lubrication，And then there are foreign bodies，The error of bearing assembly and the deflection of shaft are large、The study of shaft and bearing box is not enough。So to speak，These causes overlap more often than not。

introduction：The classification of bearing housing generally includes：It can be dissected and separated、scrollable、It can be used to slide，In addition, there are some bearing seats with flange functions，Different classification，Therefore, there are also great differences in the use of functions，Different bearing houses have different functions，So when buying, be sure to choose according to your own needs。 The above is an introduction to the bearing housing types，There are a lot of different types on the market，Therefore, users with needs should choose according to the kind of function they want to have，Check the instructions first before purchasing，Use according to the instructions。

introduction：Linear bearing is the main supporting product of linear motion system，For use with infinite stroke and cylindrical shaft。Due to the bearing and shaft point contact，So the use of small load。The steel ball spins with very little friction resistance，Thus, high precision smooth motion can be obtained。 Linear bearings are widely used in electronic equipment，Tensile testing machine and digital three-dimensional coordinate measuring equipment and other precision equipment，And multi-axis machine tools、Punching machine、Tool grinder、Automatic gas cutting machine、Printer card sorter、Food machinery and other industries。

introduction：Ceramic ball bearings are not only beautiful in appearance，It has several advantages at the same time： one、High speed of revolution：The ceramic ball has oil-free self-lubricating properties,The friction coefficient of ceramic ball is small,Therefore, ceramic ball bearings have a high speed.According to statistics, the bearing using ceramic ball is the speed of the general bearing1.5Times more rotational speed. two、High temperature resistance：The thermal expansion coefficient of ceramic ball is small,In the high temperature environment will not cause the bearing ball to expand due to temperature,This greatly improves the service temperature of the entire bearing,The temperature of ordinary bearings in160Degree or so,Ceramic balls can be reached220Degree or above. three、Long life：Ceramic balls can be made without any grease,Which means even if the grease dries out,The bearings are still operational,In this way, the occurrence of premature bearing damage caused by grease drying in ordinary bearings is avoided.A

introduction：Miniature bearings are used as precision parts on mechanical equipment，How to improve the production efficiency of the plant，First of all, the mechanical equipment performance must be good，And the use of mechanical equipment performance is related to it——bearing。Therefore, when the factory is in production and processing，Be sure to carry out a good inspection of bearings in mechanical equipment。 1、Voice recognition Sound recognition requires a lot of experience。Adequate training is required to be able to recognize bearing and non-bearing sounds。For this purpose，The work should be carried out by special persons as far as possible。The sound of the bearing can be clearly heard with a listening device or a listening stick attached to the housing。 2、Identification by operating temperature

introduction：Tapered roller bearings mainly bear radial diameters、Axial combined load。Bearing capacity depends on the raceway Angle of the outer ring，The greater the Angle, the greater the load capacity。This type of bearing belongs to the separation type，According to the rolling element in the bearing The number of columns is divided into single columns、Double and quadruple row tapered roller bearings。Single-row tapered roller bearing clearance needs to be adjusted by the user during installation；Double row and four row tapered roller bearing clearance has been set at the factory according to user requirements，unnecessary Household adjustment。 Tapered roller bearings have conical inner ring and outer ring raceways，Conical rollers are arranged between the two。The projected lines of all conical surfaces meet at the same point on the bearing axis。This design makes tapered roller bearings Especially suitable to withstand the combination（Radial and axial）load。The axial load capacity of a bearing is mostly determined by the con

introduction：Needle roller bearing is one of the important parts in todays industrial production，How to choose the right needle roller bearing is crucial。therefore，It is necessary to fully understand the structure and characteristics of the selected needle roller bearings，And install and use correctly。Needle roller bearing selection，The following factors must be fully considered： (1The size of the needle bearing load、Direction and nature； (2)Rotation speed and inner or outer ring rotation； (3)Required life of needle roller bearings； (4)Ambient temperature of needle roller bearings； (5)Bearing accuracy； (6)Magnitude of friction； (7)Noise requirement；
