The application characteristics of imported bearings are analyzed

The use characteristics of imported bearings: First, they are designed and manufactured on the basis of the combination system, there are a lot of motor combinations and installation forms, and the transmission ratio is very fine at each level, which can meet different use situations。Second, they use the modular design principle of the unit structure, so that a large number of...

The harm of FAG bearing metamorphic layer is described briefly

1, cold plastic deformation layer: in the grinding process, every moment of abrasive is equivalent to a cutting edge。However, in many cases, the front Angle of the cutting edge is negative, and the abrasive particle in addition to the cutting effect is to make the workpiece surface withstand the extrusion action (ploughing action), leaving an obvious plastic deformation layer on the workpiece surface。这...

Why bearing health design is critical to food safety

The hygienic design of food machinery plays an important role in controlling food safety。 However, if this concept is applied generally without considering the hygienic design of equipment components, there is a risk of bacterial growth and spread in bearings, Davide Zanghi, SKF Hygiene...

Detection of bearing operation process

The rolling sound of the bearing: the sounder is used to check the size and sound quality of the rolling sound of the bearing in operation. Even if the bearing has a very slight scratch, it will emit abnormal and irregular sounds. The sounder can solve this problem well。If the lubrication and installation part are suitable, the bearing temperature will rise rapidly, and the temperature will...

Detection of radial clearance of bearing

According to the functional characteristics of the bearing and the difference in the application of operating conditions, after the selection of the appropriate bearing type, it is also necessary to carry out routine inspection of the bearing, which includes the specification and processing accuracy of the bearing and assembly parts, the quality of lubrication, whether there is wear phenomenon of the parts and so on。Of course, after looking at the bearings,...

Application of lubricating oil in bearing maintenance

What role can lubricating oil mainly play in the maintenance of bearings？What is the connection with the maintenance of bearings？The first is the speed of movement: the higher the speed, the easier it is to form an oil wedge, and low viscosity lubricating oil can be used to ensure the existence of the oil film。If the viscosity is too high, the impedance is large, the heat is relatively large, and the temperature will be caused...

How to determine whether there is noise in the SKF bearing in the wheel

When one of the SKF bearings of the four wheels of the vehicle is damaged, you will hear a continuous buzz-buzz-buzz sound in the car while it is moving。It even feels like the whole car is filled with this sound, and the faster the car is getting louder。General speed from about 60km/h can hear a slight hum...

The United States anti-dumping against Chinese tapered roller bearings and their parts

At the recently concluded 2018 World Economic Forum in Davos, the protectionist trade policies of the United States became the target of public criticism。However, the US side seems indifferent to this and even defends trade protectionism。At the first press conference between US Treasury Secretary Steven Mnuchin and Commerce Secretary Wilbur Ross, "Guarantee...

Why do most of China's high-end bearings need to rely on imports...

In this world, in addition to the earth, anything that needs to be rotated needs bearings。　　Bearings exist in almost every corner of our lives。From the shared bicycles all over the ground to the civil aircraft skimming overhead, from the nuclear submarine to the space station surveying the sky, and then to the refrigerator, washing machine, electricity...

The important role of plastic extruder bearings!

The plastic extruder bearing is used in the plastic extruder, then an important part of the plastic extruder is the drive mechanism。It controls the rotation speed of the screw, and the rotation speed of the screw determines the output of the plastic extruder。 The power required is determined by the viscosity (flow resistance) of the polymer。polymeric...
