introduction：Purpose of micro-bearing lubrication The method of lubrication and lubricant directly affect the life of the bearing。Select suitable lubrication according to different conditions of use。 The effects of lubrication are described below： (1 ）Reduce friction and wear Lubrication can reduce the rolling friction between the rolling element and the raceway、Sliding friction between rolling element and cage。 Sliding friction between cage and ferrule。 (2）Reduce heat generation Eliminate heat produced inside the bearing or heat from outside，Prevent bearing overheating and lubricant deterioration。

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 number of columns of rolling elements in the bearing 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，No user adjustment required。 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 particularly suited to withstand recombination（Radial and axial）load。Most of the axial load of the bearing is determined by the contact Angle Ti

introduction：Since the realization of mechanization、Automatic production of needle roller bearings，In addition to the production efficiency of the product has been improved a lot，The quality of the products has also improved significantly，Includes the load force of the needle roller bearing，This is crucial to the selection of the entire product。 Because of the different bearing load is also different，Generally speaking，Needle roller bearings can be used to withstand heavy loads；Ball bearings are used for light or moderate loads；Bearings made of carburized steel or hardened with bainite，Withstand shock and vibration loads。It can be seen that，For security reasons，Bearing characteristics must be understood in industrial manufacturing。 If the load of the needle roller bearing is not enough，It will cause very large losses to the later use of bearings，It will even directly affect the operation of the entire mechanical equipment。And a good needle roller bearing can give full play to its role，Make the equipment drive smoothly，Imp

introduction：Although the structure of the outer spherical bearing is very different compared to other types of bearings，But its installation is only one step ahead of them，That is, the fixing of the outer ring。Of course，Fixing the outer ring of the spherical bearing is also skillful，Otherwise, it will lead to low fit inside and outside the bearing。In this case, if the outer spherical bearing is running at high speed，Its very easy to damage the bearing，What can be done to fix the outer ring of the outer spherical bearing in place？ First of all，Need to remove the bearing jacket fixing pin first，And ensure that the surface of the shaft diameter is smooth and clean，Apply or spray anti-rust oils and lubricants as appropriate。Before loading the outer spherical bearing into the housing，Make sure to apply the right amount of lubricant evenly between the two，Then place the merge where it needs to be installed，Wait for next installation。

introduction：Fixed shaft joint bearing To prevent unnecessary bearing on the shaft or inside the house movement, The bearings of the ring and outer ring should be axial。Axial fixation includes axial position and axial fastening。 1、Axial direction Reference end bearing inner ring shoulder positioning support positioning outer ring of housing hole。To ensure the bearing face and shaft （Gear wheel） Shoulder close，Should ensure at the time of design （block），Shoulder Angle r Less than the bearing assembly chamfer;To transfer the axial load and easy assembly and removal of the shaft （Gear wheel） There should be a certain height on the shoulders。Shaft selected according to bearing assembly chamfer （Gear wheel） Shoulder height。

introduction：The first thing we need to pay attention to is the use of linear bearings，Be sure to follow the prescribed operating procedures，For example, should we check before opening every day to see if the linear bearing can rotate，These little details，A lot of places in use，Didnt really follow it，Dont look as if it does not affect the use of the product for the time being，But it took a long time，It will cause irreversible damage to the product，Especially for a product that needs to be used all year round，It is necessary to pay attention to these details，Cant be neglected at all。
