introduction：Crossbar bearing market，There are domestic ones，Some do import，Domestic we are not particularly clear，But imported，We know each other well。passINAFailure and deterioration of imported bearings，Performance state parameters to judge and predict bearing reliability and performance，On the part of the anomaly，Causes and risk levels are identified and judged to determine repair and improvement methods。In the absence of equipment monitoring，We can also listen through、Two kinds of touch、Three observation methods to determineINADamage degree of imported bearings。1、listen：Hearing is a common way to identify irregular movements。Such as with a screwdriver or an electronic stethoscope

introduction：YTPLinear bearing installation process，Bearing deformation is a very real situation，Various engineerszuiAll I care about is how do you do it right，If not done properly, it could causeYTPBearing damage。If operating at high speed，And the operating temperature is higher，Special attention should be paid to the fitting of the rotating ring not too loose，To prevent eccentric vibration，And the match of the fixed ring should not have a gap，To prevent the ring from deforming under load and exciting vibration。The cauterization of the rotating ferrule should be small to the extent possible。As long as the effect of thermal expansion at working temperature is guaranteed，And the influence of centrifugal force at high rotational speed，

introduction：PMIBall screw，Can be called ball screw，I dont know about the high load seriesPMIHow much do you know about ball screws？Lets go and find out！one、High life cycle structure allows for uniform load distribution within the nuts，Improve the service life of the ball screw。In the old circulation mode, the return pipe was inserted vertically into the ball groove to form a forward Angle，When the ball enters the return pipe, it will hit the return pipe and bounce into the return pipe。two、highDNThe value is constructed by tangential circulation between the steel ball and the return track，usableDNValue higher on high speed requirements。three、Low noise because of the tangential circulation structure，

introduction：With the rapid development of science and technology，Bearings are also more and more widely used，But the high speed of the bearing often leads to：Dispersion of lubricant，Hard to attach，The centrifugal force increases the contact stress sharply，Friction increase，Heat surge and so on。Today Xiaobian will introduce you aboutFAGLinear bearing heating causes and treatment methods related content，The basic situation is as follows：one、Causes of bearing heating1、The processing quality of the bearing itself is poor. The outer ring with bearing steel as the raw material、A friction pair composed of a roller and a cage made of bronze，The ability to withstand foreign objects is relatively low，Although it has the lubricating effect of bearing grease，however

introduction：The so-called bearing clearance，That is, when the bearing is not installed in the shaft or bearing box，Fasten one of its inner or outer rings，Then the amount of movement when the unfixed party makes a radial or axial movement。By direction of movement，It can be divided into radial clearance and axial clearance。Suitable bearing clearance is helpful to the normal operation of rolling bearings，Too little clearance，The temperature of rolling bearing rises，Out of order，And the rolling element is stuck；Excessive clearance，High vibration of equipment，The rolling bearing is noisy。How to measure bearing clearance，Become a necessary skill to master。The following Xiaobian will teach youFAGTest method for radial clearance of linear bearings，Method for checking axial clearance。
