Shaft Linear Bearing For Beijing Zhongli/Jwell Manufacturers

What factors affect the accuracy of Shaft Linear Bearing?

1. Manufacturing accuracy of bearings

The accuracy of axial linear bearings is closely related to the accuracy during their manufacturing process. During the production process, factors such as the inner and outer ring size of the bearing, the shape of the rolling element and the surface finish will affect the accuracy of the bearing. If there is processing error during the manufacturing process, such as insufficient roundness or excessive surface roughness, it will cause unnecessary friction during the bearing operation, affecting the stability of the equipment. Therefore, high-precision manufacturing process and strict quality control are the basis for ensuring the accuracy of axial linear bearings.

2. Axis accuracy

The mating relationship between the bearing and the shaft is crucial to the accuracy of the bearing. If the surface quality of the shaft is poor, or the machining accuracy of the shaft is not high, the operating accuracy of the bearing will be reduced. The surface roughness and concentricity of the shaft have a great impact on the operation of the bearing. If the axis has a large deviation in linearity or concentricity, the bearing will bear uneven loads, which will affect the accuracy. In order to ensure the best fit, the accuracy of the shaft should be strictly matched with the design requirements of the bearing.

3. Installation accuracy

Even if the manufacturing accuracy of the bearing and shaft meets the standard, improper installation accuracy will still affect the accuracy of the bearing. During installation, if the bearing is not properly centered or is disturbed by external forces during installation, it may cause the bearing to be offset or deformed, affecting its working performance. Correct installation methods and ensuring accuracy during installation can effectively prevent these problems from occurring and ensure that the bearings can work in the best condition.

4. Lubrication and cleanliness

The lubricating state of axial linear bearings has a profound impact on their accuracy. Reasonable lubrication can reduce friction, reduce wear and maintain the accuracy of the bearing. However, if the lubricant oil is of poor quality or is improperly lubricated and the friction increases, the bearing may wear prematurely, resulting in a decrease in accuracy. In addition, the cleanliness of the bearings are also important. If dust, impurities and other foreign matters accumulate inside the bearing, it will increase friction and may even cause stagnation, which will ultimately affect the accuracy. Therefore, regular lubrication and cleaning maintenance are very important to maintain the long-term accuracy of the bearing.

5. Selection of material

The material of axial linear bearings directly affects its wear resistance, corrosion resistance and deformation resistance. If the material is not selected properly, the bearing is prone to wear or corrosion under high loads or special environments, resulting in a decrease in accuracy. For example, under high temperature environments, bearings made of ordinary materials may experience thermal expansion, which will lead to a decrease in accuracy. Therefore, selecting suitable materials and making reasonable material selection according to different working environments can effectively improve the accuracy and service life of the bearing.

In this regard, Jiaxing Shengbang Mechanical Equipment Co., Ltd. uses high-quality alloy steel and special materials, which have high hardness and good corrosion resistance, and can maintain high accuracy even in harsh environments. By choosing different materials, Jiaxing Shengbang's axial linear bearings can maintain high precision and long-term stable performance under a variety of operating conditions.

6. Temperature changes

Temperature also has a certain impact on the accuracy of axial linear bearings. The material expands or contracts at high or low temperatures, and this physical change may cause deviations in the working accuracy of the bearing. Under high temperature conditions, the internal lubricant of the bearing may lose its original lubricating effect, while in low temperature environments, the increased viscosity of the lubricant may lead to poor lubricating effect. Therefore, temperature changes are an important factor affecting the accuracy of axial linear bearings, especially in working environments with large temperature fluctuations, temperature control measures are particularly important.

7. Load and operation speed

Load and operating speed are also key factors affecting the accuracy of axial linear bearings. High loads or too fast running speeds can increase friction inside the bearing, resulting in faster wear and loss of accuracy. Especially under long-term and high-frequency operation, the accuracy of the bearing is easily affected. Therefore, when choosing bearings, the working load and operating speed of the bearings must be taken into account to ensure that they can maintain good accuracy under these conditions.

8. Impact of the work environment

The accuracy of axial linear bearings is also affected by the working environment. Factors such as high humidity, dust, and chemical corrosion will affect the long-term stability of the bearing. In humid environments, bearings are susceptible to corrosion, resulting in degradation of material properties, which in turn affects its accuracy; in environments with a large amount of dust or particulate matter, these particles may accumulate inside the bearing, resulting in increased friction, which in turn affects the accuracy. Therefore, the working environment of the bearing needs to be kept clean and dry as much as possible to avoid negative impacts on the accuracy of external factors.

9. Impact of dynamic load

During operation, bearings are usually affected by various dynamic loads. These dynamic loads may cause slight displacement of the bearing during movement, which in turn affects its accuracy. Changes in dynamic loads may cause components inside the bearing to vibrate, resulting in additional friction or uneven loads, which in turn affects the accuracy of the bearing. Therefore, bearing designs that adapt to dynamic load changes are key to ensuring high-precision operation.
