Material selection for bearings: key factors and common materials
The selection of suitable materials is crucial for the performance and lifespan of bearings. Different application environments and working conditions require bearings to have different physical and chemical properties. This article will explore the key factors that affect material selection and common bearing materials.
1. Factors affecting material selection: When selecting bearing materials, the following key factors need to be considered:
How to deal with the temperature impact of bearings
The temperature control of bearings during operation is crucial for their performance and lifespan. Excessive or insufficient temperature can cause damage to bearings and affect their normal operation. This article will explore the impact of temperature on bearing performance and how to maintain bearings under extreme temperature conditions.
1. The effect of temperature on bearings: When bearings overheat, it can cause the decomposition of lubricating oil, reduce lubrication effectiveness, and increase wear. Long term high temperature may also lead to a decrease in material properties. On the contrary, excessively low temperatures may lead to excessive viscosity of lubricating oil, affecting the rolling of bearings.
2. Maintenance of bearings under high temperature conditions. Bearings working in high temperature environments require special attention to lubrication. Choose lubricating oil that can maintain performance at high temperatures and regularly check and replenish it. In addition, consider using bearings made of high-temperature resistant materials to improve their performance
Bearing installation and disassembly techniques: ensuring better performance
Introduction: Proper installation and disassembly of bearings are crucial for ensuring their performance and extending their service life. Improper installation or disassembly methods may not only damage bearings, but also affect the performance of the entire mechanical system. This article will introduce some basic installation and disassembly techniques.
1. Preparation before installation: Before installing bearings, it is important to ensure that all tools and working environments are clean. Check the dimensions and surface roughness of the shaft and seat holes to ensure they meet the specified tolerances and fit requirements.
