introduction：The outer spherical bearing is actually a kind of deep groove ball bearing,It is characterized by its outer diameter against the sphere,Can match the corresponding concave spherical bearing aligning effect。Although its basic performance and deep groove ball bearings should be similar,But because bearings are mainly used for mechanical roughness,When the installation position is incorrect,The axis is neutral to the axis of the hole,Or under conditions of large axial length and deflection,And bearing itself accuracy is not high,Some rough structures,Therefore, the actual performance of the performance comparison in the same specification of deep groove ball bearings play a great discount。 Such as,The outer spherical bearing of the top wire is used for deflection of the large shaft、The stiffness difference between this bearing and seal is on both sides,It can prevent dust intrusion,Keep an eye on the factories that have been loaded Proper lubricant,No need to clean before installation,No need to lubricate,The be

introduction：The following Xiaobian we talk about when buying linear bearings，I know about the bearing problem。The purpose is to optimize the selection of bearings，Ensure the excellent quality of bearings。For this reason, we are required to understand the quality of bearings。 Therefore, it is recommended that you understand which linear bearings are good，Pay attention to see whether the white surface of the bearing has muddy oil。 At present, the domestic rust prevention technology has not reached the international standard，Therefore, it is easy to leave a thick oil stain when the bearing body is treated with rust，Such bearings can be sticky in the hand，Many foreign original imported bearings can hardly see traces of anti-rust oil。So by looking at the bearing surface whether there is a muddy oil，It can promote the quality of bearings to a certain extent，Ensure that the purchased bearings have been optimized for rust prevention，It has good anti-rust properties，Of better quality。

introduction：Although the characteristics and performance of grease will be affected by the production process and raw materials。But in fact，Greases cannot be compared or selected on the basis of composition alone。therefore，Performance testing of greases is required，To obtain important information for practical applications。In the last hundred years or so，KOYOBearing grease、The interactions between materials and surfaces have been studied in depth and a great deal of knowledge has been accumulated。 KOYOThis knowledge has been used to establish industry standards for the performance testing of bearing greases。To evaluate the performance of the bearing grease in operation，KOYOMany test standards have been developed for bearings，Such as, Emcor.ROF,ROF+,V2F,R2FandBequietAnd so on。

introduction：Linear bearings are precision parts，Therefore, it is required to be quite careful when using，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 matters： one、Keep bearings and their surroundings clean Even the tiny dust invisible to the naked eye enters the bearing，It will also increase bearing wear，Vibration and noise。 two、Be careful when using the installation Strong stamping is not allowed，It is not allowed to hit the bearing directly with the hammer，Pressure transfer through rolling elements is not allowed。 three、Appropriate use、Accurate installation tools Use special tools whenever possible，Avoid things like cloth and staple fibers。

introduction：Axial positioning of linear bearing and several positioning methods How is the linear bearing positioned，The following Xiaobian to tell you about it。 It is not enough to position the bearing ring axially only by interference fit。usual，It is necessary to adopt some suitable methods for axial positioning of the bearing ring。The inner and outer rings of the positioning bearings should be axially fixed on both sides。 The axial fastening of bearings includes axial positioning and axial fixing。To prevent the bearing from moving on the shaft and in the bearing seat hole，The bearing inner ring must be fastened to the shaft；The outer ring must be fastened in the bearing seat hole（Or set cup inside）。Bearing insides、Whether the outer ring needs to be tightened in both directions or in one direction，Or axial swimming，Depends on the limit requirements of the support and the type of bearing used。Supports at bi-directional limits（Immediate fixed support）In the，The inner ring of the bearing is on the shaft，The outer ring sha
