Why does the precision bearing turn black and blue? Various common failure causes and solutions

2021-11-15 in /by

When we use precision bearings, we will find that the bearings turn black and blue. This is caused by improper operation during use or installation. How should we solve it? Next, the precision bearing manufacturer will introduce the reasons and solutions for the black and blue of precision bearings and other common faults. Let’s take a look! Precision bearings turn black and blue Cause Analysis 1. In use, the bearing will turn black and blue when it is burnt due to the high temperature; 2. When the precision bearing is installed by heating method, the bearing is annealed due to the high heating temperature, which reduces the hardness of the bearing. Solution 1. Pay attention to the correct use of bearings and strictly control the temperature; 2. When using the heating method to install the bearing, the heating temperature should be controlled according to the regulations and the operation should […]

What materials are used for high-speed bearings? Material requirements for bearings and components

2019-01-02 in /by

Compared with other bearings, high-speed bearings have special requirements in terms of materials, so as to ensure that the manufactured bearings can exert better performance, so what materials are used for high-speed bearings? Now the editor of Rockewell will introduce to you what are the requirements for materials used in high-speed bearings and various components! 1. Material requirements for high-speed bearings 1) high temperature hardness High-speed bearings have high temperature themselves or work at high temperatures, so the requirements for high-temperature conditions are different. For example, high-speed bearings working at a temperature of 220°C require high-temperature materials to be selected at 315°C. This is because high-speed bearings require more High temperature hardness, so as to resist the deformation tendency caused by the speed effect at high speed. The commonly used steels for high-speed bearings usually used at high temperatures are M50, M2, WB49, and M315, etc. Among them, M50 steel […]

How to clean precision angular contact ball bearings correctly?

2018-12-26 in /by

When we use precision angular contact ball bearings, we all know that the bearings need to be cleaned after a period of use, in order to increase the operating efficiency of the equipment and prolong the service life. But many people use the wrong cleaning method, so how to clean precision angular contact ball bearings correctly? Let’s introduce it to you from the editor of Rockwell! 1. Wrong cleaning method of precision angular contact ball bearings Now many precision angular contact ball bearing manufacturers generally use the wrong cleaning process, and they continue to use the old process decades ago, which is to prepare a basin of gasoline and a basin of kerosene, and put the bearing in the basin to rotate. Cleaning, whether it is immersing all the bearings in oil for cleaning, or immersing half of the bearings in oil and rotating and cleaning, can not clean the […]

What are the main forms of damage to sealed angular contact ball bearings? Causes and solutions

2018-12-24 in /by

Sealed angular contact ball bearings will fail after being used for a period of time. Different failures prove that the bearing has suffered different degrees of damage. At this time, we need to analyze the causes according to different damages and solve them in time. Then the sealed angular contact ball bearings are damaged. What are the main forms? Let’s analyze it for you in the following editor from Rockwell! Sealed angular contact ball bearings have three main types of damage, such as peeling, seizing, and cracking. Let’s take a look at how to solve these three different types of damage! 1. The sealed angular contact ball bearing is peeling off The peeling of sealed angular contact ball bearings refers to the peeling of the inner and outer ring raceway surfaces or rolling surfaces due to fatigue. There are two types of peeling. One is that after the bearing has […]

Causes and treatment of burnt of steel ball of sealed angular contact ball bearing

2018-12-19 in /by

The steel ball burns of sealed angular contact ball bearings are relatively easy to produce during hard grinding, which may cause soft point defects in the bearing and reduce the life of the steel ball. What should I do if the steel ball burns? Now let the editor of Rockewell introduce to you the cause and treatment of the burnt of the sealed angular contact ball bearing steel ball! 1. Sealed angular contact ball bearing steel ball line burns Line burn means that the rolling contact point of the steel ball produces a certain friction temperature under the action of the grinding pressure and speed. When the friction temperature reaches the quenching or tempering temperature of the metal, and it is immediately cooled by the coolant, it becomes a line. Shape secondary quenching or tempering burns. There are many reasons for line burns: 1) The flares of the steel ball […]

How to maintain sealed angular contact bearings? Maintenance steps and precautions

2018-12-16 in /by

Sealed angular contact ball bearings must be maintained regularly during use. Maintenance is for the bearings to run stably for a longer period of time. If they are used all the time without maintenance, the service life of the bearing will be reduced and the failure rate will increase, so maintenance work It is very important. Let’s talk about how to maintain sealed angular contact bearings by Rockwell editor below! 1. Maintenance steps of sealed angular contact bearings 1) When the sealed angular contact bearing is running for a certain period of time, or when the maintenance period is reached, all the bearings need to be removed for maintenance and repair. 2) When cleaning the bearings, diesel or kerosene should be used to soak and clean the bearings. If possible, the sealing cover can be opened to clean the bearings. 3) After cleaning, check to ensure that the cleaning oil […]
