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.

ZYS High-speed Angular Contact Ball Bearings

High Precision Angular Contact Ball Bearings are our hot products. We have been engaged in research and development of High Precision Angular Contact Ball Bearings since 1958. ZYS has set up a scientific research workstation, and a strong world class experts team for High Precision Angular Contact Ball Bearings, whose main researches represent the technology developing direction of China bearing industry. So we bring you the High Precision Angular Contact Ball Bearings with best quality , high precision, reliable performance and strong durability.

1. Application of High-speed Angular Contact Ball Bearings:

•Machine tool spindle

•Robot technology

•high-frequency motor

•gas turbine

•centrifuge

•small-size automobile front wheels

•differential pinion shaft 

2. Advantages of High-speed Angular Contact Ball Bearings:

The inner ring, outer ring and rolling element of High-speed Angular Contact Ball Bearings are made in high carbon chromium bearing steel. The chamfer arc radius of rings is reasonable, which is not only convenient to install, but also guaranteed to improve the installation precision and reduce the risk of the related parts being bumped. 

•The speed performance of High-speed Angular Contact Ball Bearings is outstanding. 

•Unique heat treatment process of High-speed Angular Contact Ball Bearings allows products to achieve the best dimensional stability and rigidity, so as to reduce wear and tear. 

•Multiple pre-load levels can help to meet different requirements for speed and system stiffness, which is more reasonable to select and use the levels.

Why is there noise in the bearing? I

1. Fatigue peeling

On the raceway or rolling body surface of the rolling bearing, the surface metal of the contact surface is peeling off and gradually expands to form a dent because of bearing the alternating load. If it continues to run, it will form big peeling area. Due to improper installation or the inclination of the center line of the bearing seat and the axis, the local area of the bearing will bear larger load and then appears early fatigue damage.

2. Crack and fracture

 If the material has defects and heat treatment is not proper, the interference amount is too large and the combination design is improper, it will cause stress concentration and then the ring crack and fracture will be formed.

3. Indentation

When the external material enters the bearing between the rolling body and the raceway, the rolling surface can be indented. In addition, excessive impact load can also lead to plastic deformation of the contact surface and then the formation of pits. When the bearing is still, even if the load is very small, uniformly distributed pit will be formed in the raceway due to the vibration of the surrounding environment.

ZYS wind turbine bearing

Bearing type is the air-cooled heat sink fan-shaped bearing type used. In mechanical engineering,Wind turbine bearing ,bearing class shaped very much, but also on the radiator so few products in use, the use of sliding friction sleeve bearings and use a rolling bearing friction ball bearings and two forms of combining these three.


The use of oil-bearing sliding friction sleeve bearings, when used as a lubricant and lubricant DRA initially run using low noise,angular contact thrust ball bearing , low manufacturing costs, but this badly worn bearings, ball bearing life than there is a big gap.

Ball bearing profiles and composition structure

Ball bearing profiles and composition structure
There are single row radial Deep groove ball bearing, double row spherical, radial thrust, thrust and thrust to the heart and other structural types. ① single row radial ball bearings: compact, easy to use, and wide application. Mainly used to bear radial load, it can withstand a certain amount of axial load. In the high-speed device, it can also be used to replace the thrust bearing. This Order of the friction is small, extreme high speed, suitable for rigid large double bearing axis.
Structure and composition
Ball bearings are mainly made up of four basic elements: ball, inner ring, outer ring and the cage or retainer. Ball and ring usually high chromium steel, Rockwell hardness of between about 61-65. While maintaining the low hardness compared to the balls and the ring, which material has a metal or metalloid. ball bearing rotation than the ball bearing friction is small, and therefore at the same speed, temperature and friction will be relatively low.

The investment project was Province

The investment project was  Province, and governments at all levels attach great importance.  Municipal Party secretary Wu  Municipal Committee, vice mayor  specially to attend the ceremony, met with Japan's Seiko president N party. The foundation stone laying ceremony rotary table bearing  by the High-tech Zone  Director Business Planning  N Minister Fan  served jointly presided over the ceremony. Municipal Committee, Deputy Mayor Wei  Municipal Committee, vice mayor , Municipal Committee, vice mayor Lu , attended the groundbreaking ceremony.
 Corporation president  believes that China's development is definitely the future of the center is located in central, rather than along the coast. Therefore,is the core of the product line, the global share of the first ball bearing project investment ball bearing  in  bearing production company is the first in China to set up 12 plants will be equipped with the most sophisticated equipment, NSK outside of Japan to become the largest production base. plant will be subject to local employees to operate in China, while the rapid development of industry from around the world to provide  high quality products. Inland areas will be the core of the future development of China,  able to have the opportunity to build factories and regions, contribute to the community, it is our pleasure to thank the local government to give  this opportunity.
