Sharing practical information, let you know the characteristics of Luoyang bearing steel in one minute

What are the materials of Luoyang bearing? What are the characteristics of Luoyang bearing?

　　1. Contact fatigue strength. Under the action of periodic loads, the contact surface of Luoyang bearings is easily exhausted and damaged, that is, cracking and peeling occur, which is an important damage condition of bearings. Therefore, in order to improve the service life of bearings, bearing steel must have high contact fatigue strength.

　　2. Wear resistance. During the operation of the bearing, not only rolling friction but also sliding friction will occur between the rings, rolling elements and support frames, which will keep the bearing parts in a state of wear.

　　3. Hardness. Hardness is one of the important qualities of bearing quality, which has an indirect impact on contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel in service should reach HRC61~65 respectively to enable the bearing to obtain higher contact fatigue strength and wear resistance.

　　4. Anti-rust performance. In order to avoid corrosion and rust of Luoyang bearing parts and finished products during processing, storage and use, bearing steel is required to have good anti-rust performance.

　　5. Processing performance. In the consumption process of Luoyang bearings, there are many cold and hot processes. In order to meet the requirements of small batch and high quality, bearing steel should have good processing performance.

　　Luoyang bearings shall, in addition to the above basic requirements, also meet the requirements of appropriate chemical composition, general external structure, few non-metallic impurities, appearance defects complying with the specifications, and decarburization layer not exceeding the specified concentration.

　　Whether the Luoyang bearing is installed correctly affects its accuracy, life and performance. Therefore, the design and assembly department must fully study the installation of the bearing and hope to install it according to the operating standards. The standard items of the operation are usually as follows: (1) Clean the bearing and bearing-related parts. (2) Check the size and finish of related parts. (3) Installation. (4) Inspection after installation of the bearing. (5) Supply lubricant.

Before installation, the Luoyang bearing package was opened. Generally, grease lubrication is used without cleaning and grease is directly filled. Lubricating oil lubrication does not usually require cleaning. However, bearings for instruments or high-speed use should be cleaned with clean oil to remove the rust inhibitor applied to the bearings. Bearings with the rust inhibitor removed are prone to rust, so they cannot be left alone. Furthermore, bearings that have been sealed with grease should be used directly without cleaning.

　　The installation method of Luoyang bearings varies according to the bearing structure, fit, and conditions. Generally, since the shaft rotates, the inner ring requires an interference fit. Cylindrical bore bearings are mostly pressed in with a press or hot-fitted. In the case of tapered holes, they are directly installed on the tapered shaft or installed with a sleeve.

　　Luoyang bearingWhen installed into the housing, there is generally more clearance and the outer ring has an interference fit. It is usually pressed in with a press, or there is a shrink fit method for installation after cooling, using dry ice as a coolant. When shrink fit is installed, the moisture in the air will condense on the surface of the bearing. Therefore, appropriate anti-rust measures are needed.
