FANADE Industry(HongKong) Ltd,with annual output capacity of a large quantity of 608 Bearing From Fag as well as 80 million sets of needle roller bearings and 2 billion of needle rollers,covers an area of 6200 square meters and construction area of 3500 square meters Its main product series include drawn cup needle roller bearings,drawn cup needle roller clutches,roller bearings,cylindrical roller clutches and ball bearing components,thrust bearings,roller bearings,linear motion guide roller bearing and rolling bodies(FANADE Bearing Seals Type include:RS,2RS,Z,2Z,2RZ,DDU,LLU,VV.Bearing Row:Single-Row,Double-Row,Four-Row) etc with imported and domestic famous brands including Swedish SKF bearings,German FAG,INA bearings,Japanese NSK bearings,Japanese NTN bearings,Japanese KOYO,FYH bearings,Japanese IKO bearings,American TIMKEN bearings,Britain RHP and other famous imported bearings.FANADE Bearing website provide Structure、Dimensions、Net Weight and all Parameter and Details of all kind of bearings.Here we'd like to talk about The cause of the loss of bearing vibration.

Bearing use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements.

Loss bearing for many reasons, all the influence factors of design and manufacturing process will be associated with the loss of bearing, the analysis is bad judgment. But in general, generally can be used from the two aspects of factors and internal factors considered and analyzed.

Loss of SKF bearing use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. Installation conditions is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and loss. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. In addition, analyze the grease and the surrounding medium, the atmosphere quality inspection is also very important.

According to SKF bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. Installation condition is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing.

1) bearing design parameters: including the number of rolling element bearings, ring throwing, wall thickness and clearance, etc.

2) the manufacturing error of bearing parts: including the bearing raceway and rolling body surface roughness, grain degree and the roundness error. A large number of experimental study show that the waviness on the influence of the bearing vibration dominate, and the influence of surface roughness and the roundness is relatively small.

3) bearing working conditions: bearing in the process of operation, load, speed, lubrication condition the influence of the three aspects of bearing vibration is the largest.

4) SKF bearing installation parameters, bearing and shaft and bearing seat, and the bias of installation and other factors also affect the vibration of the bearing.
