What are the hazards of using shoddy bearings, KOYO needle roller bearings, and shoddy imported KOYO

1. Due to the limitation of raw materials, the hardness of shoddy bearings cannot meet the national requirements. In use, there will be deformation, etc., which will affect its service life and damage other parts of the machine. Especially for some high-temperature bearings and high-speed bearings, the hardness of the bearing directly affects its service life and safety of use.

2. Due to the limitation of the dipping technology of small manufacturers and underground factories, the heating temperature of the cylinder pads of the shoddy bearings is uneven, which affects the precision of the bearings and deformation.

3. Its huge technical limitations directly affect the precision of these bearings, making this problem an insurmountable hard injury, and the gap in precision not only directly damages the parts of the machine, but also makes the bearing loading and unloading a more cumbersome matter, and even can be installed and not used, can not be used to remove the situation, directly damage the machine, delay the working hours.

4. In order to reduce costs, some small manufacturers and illegal processing plants use inferior steel, mar steel, carbon steel and other raw materials, and at the same time reduce the process in the production process, these products are prone to problems in the use process, and even directly scrap the machinery and equipment. In order to protect their own rights and interests, consumers should not only enhance their legal awareness, but also learn to identify and select the best bearings, so as to avoid irreparable damage to the equipment.

The hazards of using shoddy bearings Koyo needle roller bearings and shoddy imported koyo needle roller bearings: deformation will occur in use, which will affect its service life and damage other parts of the machine. It affects the precision of the bearing, and deformation occurs.

There is a situation that it can be installed and not used, and it can be used but cannot be removed, which directly damages the machine and delays working hours. Scrapping machinery and equipment.

KOYO Bearing is a precision part of imported bearings, and KOYO Bearing supports mechanical services, preventive maintenance methods, condition monitoring and a series of residual maintenance work, and the system realizes the optimization of workshop asset efficiency and maintenance work. Therefore, KOYO bearings have played a vital role in some industries.

KOYO Bearings are precision parts in imported bearings, and KOYO imported bearings are used to optimize the efficiency of workshop assets and maintenance work for decision support for mechanical services, preventive maintenance methods, condition monitoring and a series of maintenance work. Therefore, KOYO bearings have played a vital role in some industries.

However, if there is any defect in the KOYO bearing described below, it should not be used again and should be replaced with a new KOYO bearing immediately. The details are as follows:

a) There are cracks or notches in any one of the inner ring, outer ring, rolling element and cage of KOYO bearing;

b) There is a fracture in any one of the rings and rolling elements of the KOYO bearing;

c) There are significant jams on the raceway surface, flange and rolling elements of the KOYO bearing;

d) The cage of the koyo bearing is significantly worn, or the rivet is significantly relaxed;

e) Raceways of Koyo bearings.

1. NSK bearing coordination should be able to make the bearing installation and disassembly simple and convenient, so it is good to save time, labor and cost as much as possible.

2. In addition, the ferrule cannot slide along the tangential direction in its mating surface, so as not to damage the mating surface.

3. In order to reduce the deformation degree of the spherical roller bearing ring and give full play to the bearing capacity, it is best to have good support and uniform force on the bearing ring.

4. It must adapt to the axial position and have the ability to swim within a certain range, so the free end bearing must be able to adapt to the length change of the shaft and the bearing housing hole.

The first noise related to bearing manufacturing: This includes cage noise and vibrato, cage noise mainly occurs in ball bearings and tapered roller bearings, when the combined bearing rotates, it will make a sound due to the vibration of the cage and the impact of the cage with the rolling elements. This sound is cyclical.

Vibrato (various bearings) is a sound with a certain frequency, which is produced by vibration caused by a large waviness on the raceway surface.

Second, noise caused by improper use: this kind of noise is non-periodic, and it is also accompanied by vibration, and its sound volume is not fixed, and it comes and goes.

The third inherent noise: raceway sound and various bearings and rolling friction sound is the inherent sound of rolling bearing, raceway sound is produced by the elastic characteristics of the rolling element when it is in contact with the raceway, when the combined bearing rotates, the rolling element rolls on the raceway and emits a continuous and smooth sound; Abnormal rolling friction sounds can produce uncomfortable metal friction abnormal sounds such as "squeak, squeak", and do not make such sounds when lubricated well.

Properly deal with the noise of the KOYO combination needle roller bearing should be properly handled and then properly handled, hehe......

It can not be regarded as a roller bearing, generally speaking, roller bearing refers to a cylindrical roller bearing and a spherical roller bushing, and its rolling element is a thick cylinder, which has a large bearing capacity. Like njnfnun etc. Although the roller body of a needle roller bearing is technically a cylinder, it is a separate category, as are the others.
