Which type of bearing is less noisy?

The noise of bearing not only affects the bearing operation, but also brings a lot of trouble to the mechanical equipment. The intrusion of foreign materials will directly cause certain noise during the operation of the bearing, and the improper lubrication and wrong bearing installation will also cause bearing noise. Which kinds of bearings have less noise?

1. The noise of the ball bearing is lower than that of the roller bearing, and the friction noise of the bearing with less sliding is lower than that of the bearing with relatively more sliding; the bearing with more balls and thick outer ring also has smaller noise.

2. The noise of bearing with solid cage is relatively lower than that of a bearing using a stamped cage.

3. The noise of bearing with the plastic cage is lower than that of the bearings using solid cage or stamped cage.

4.Bearings with high precision, especially those with higher precision rolling elements, have lower noise than low precision bearings.

5. The noise of small bearings is relatively small compared to the noise of large bearings.

In order to maintain the good performance of the bearing, daily maintenance, inspection, overhaul, and prevention must be done. For long-running equipment, the usual inspection and tracking is particularly important, including the rotation of the bearing, vibration, temperature, lubricant status, etc. According to the test results, equipment maintenance personnel can find and deal with problems in time. ZYS will carefully analyze the technical information and application of bearing offered by the customer, and then choose the right type of bearing and inform the precautions during installation and operation.

6 methods to distinguish the false bearings

Bearing is an important part in mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient during its motion, and ensure its rotation accuracy. In production and processing, once fake bearings are used, the consequences are not only machine maintenance and even downtime, but also millions of losses for the company. Today I will share 6 methods to distinguish the false bearings.

1. Check the logo and characteristic on the package is clear or not. 
2. Check certificate of quality is standard or not. 
3. Check whether the steel print on the bearing is clear or not.
4. Check the overall quality of bearings.
5. Check the metallic luster of bearings.
6. Rotate the bearings to check whether there is noise or not. 

the lowest ball bearing average export price of products

This year, two months before Luoyang drum-shaped roller bearings export average price of 430.8 yuan each, cylindrical roller bearings average price of 390.6 yuan each, but exports were only 01,500 units and 02,700 units, compared with the average export price products with high export volume is low. The ball bearing deep groove ball average price 7.8 yuan each, the lowest average export price of products, the highest export volume.
The past two years largely maintained Luoyang Bearing exports about $ 200 million. automotive bearing exports substantially from miniature bearings, Luoyang Bearing micro level of technical quality of products have been close to international standards, has occupied a stable international market. But the lag-end bearings contain the development of the bearing industry. Since the end Luoyang Bearing in performance and price ratio, high precision, low noise, long life and high reliability and foreign bearing tester well-known enterprises there is a big gap, reflected in the market is the domestic demand for high-end bearings are still to be rely on imports to meet. Therefore, in order to maintain long-term Luoyang Bearing Industry level in a steady and rapid development, the focus should be placed on top of the R & D and industrialization of high-end bearings
