Choose The Right SKF Cylindrical Roller Bearing Material

Today Our ERIC BEARING LIMITED explain how to choose The Right SKF Cylindrical Roller Bearing Material

As we all know, bearing materials are the core and soul of a machine. Choosing the right material can improve the production efficiency and product quality of the machine, but if the quality of the selected material is poor, it will affect the product quality and the service life of the machine. It will affect the safety of users' lives. Therefore, the selection of this kind of parts is very important. Below we will give you a brief example of how to choose the appropriate cylindrical roller bearing material.

First of all, this cylindrical roller bearing material selection is particularly important. As far as the current science and technology are concerned, China's spherical roller bearing materials can be basically divided into iron and stainless steel. Generally speaking, iron components The material is lower, but because of the rougher processing, the service life is shorter. Such parts made of stainless steel have undergone anti-rust treatment and anti-wear treatment, so the price is relatively high, but it is undeniable that the service life has indeed been extended a lot.

Second, we must pay attention to the environmental protection and safety of cylindrical roller bearing materials. The operator stays indoors for almost eight hours or more every day, accompanied by these parts. If the materials containing these parts use toxic and harmful chemicals, long-term contact with the operator will inevitably lead to various diseases, damage to health, and is not conducive to the company's further development. Therefore, when purchasing parts, be sure to ask the producer what chemical products are harmful, etc., to prevent the occurrence of various occupational diseases.Cylindrical roller bearing materials are mixed in the market, and the sand and mud are all down. Consumers will be deceived if they are not careful. Therefore, when purchasing, when conditions permit, you can set up a special inspection team, shop around, compare the various situations of the seller, choose a more cost-effective seller to purchase.
 

Finally, let's explain the reasons for the noise of cylindrical roller bearings Generating vibration in bearings Generally speaking, rolling bearings do not produce noise. The "bearing noise" usually felt is actually the sound effect of the bearing directly or indirectly vibrating with the surrounding structure. This is why many times the noise problem can be regarded as a vibration problem involving the entire bearing application.Need SKF NU218 ECP,click here to learn more.

Partial damage 
Due to operational or installation errors, a small portion of the cylindrical roller bearing raceways and rolling elements may be damaged. During operation, rolling over damaged bearing components will produce specific vibration frequencies. Vibration frequency analysis can identify damaged bearing components. This principle has been applied to condition monitoring equipment to detect bearing damage. To calculate the bearing frequency, please refer to the calculation program "bearing frequency".

Accuracy of related parts
In the case of a close fit between the bearing ring and the bearing housing or the drive shaft, the bearing ring may deform due to the shape of the adjacent components. If deformation occurs, vibration may occur during operation.

Pollutant

If operating in a polluted environment, impurities may enter the bearing and be crushed by the rolling elements. The degree of vibration generated depends on the number, size, and composition of the foreign particles being crushed. Although it does not produce a typical frequency form, an irritating noise can be heard.

The reasons for the noise of cylindrical roller bearings are more complicated. One is the wear of the mating surfaces of the inner and outer rings of the bearing. As a result of this wear, the matching relationship between the bearing and the housing, and the bearing and the shaft is destroyed, which causes the axis to deviate from the correct position and produce an abnormal noise when the shaft moves at high speed. When the bearing is fatigued, the metal on the surface will peel off, which will also increase the radial clearance of the bearing and produce abnormal noise.

In addition, the lack of lubrication of the bearing, the formation of dry friction, and the crushing of the bearing will produce abnormal sounds. After Songkuang bearing wear, loose cage damage, also will produce abnormal sound.
