Physical properties of high temperature resistant materials for bearings

Porosity: refers to the percentage of pore volume in the material as a percentage of the total volume of the material. The pores of SKF bearing high temperature resistant materials can be divided into three types according to their existing forms: closed pores, one pores - pores connected to the outside atmosphere, connected pores - the proportion of the entire pores is 7L. Small SKF bearing high temperature resistant materials have the ability to resist erosion and structural strength; the higher the porosity, especially the more interconnected pores, the lower the thermal conductivity of the material. Lightweight adobe bricks, lightweight high-alumina bricks and other insulation materials use a method to increase porosity and reduce their thermal conductivity.

Reasons for seal failure of imported bearing seats and improvement plans

Reasons for seal failure of imported bearing seats and improvement plans

FAG imported bearing seat seal improvement plan "multi-stage pressure relief sealing technology" experimental bearing seat seal ring, and can reduce the leakage of lubricating oil by reducing the pressure difference between the two ends of the seal in the working environment without the need for large-scale disassembly such as shaft extraction , At the same time, the remaining leaked lubricating oil flows back to the oil tank to achieve the purpose of preventing leakage of the shaft seal.

Why do imported bearings fail and how to solve them?

Why do imported bearings fail and how to solve them?

Bearing vibration has a significant impact on bearing failure. For example: peeling, indentation, rust, cracks, wear, etc. will be reflected in the vibration detection of INA imported bearings. Therefore, the size of the vibration can be measured by using a special overall eccentric bearing vibration measurement device (frequency analyzer and vibration meter, etc.) The frequency distribution can be used to infer the details of abnormal vibration. The measured values ​​vary depending on the use conditions of INA imported bearings or the installation position of the sensor. Therefore, it is necessary to analyze and compare the measured values ​​of each machine in advance to determine the judgment scale.

How to extend the service life of FAG imported bearings

How to extend the service life of FAG imported bearings

During use, the basic external conditions of the operation of FAG imported bearings must be frequently monitored, such as temperature, vibration and noise measurements, etc. These regular inspections will detect potential problems early and prevent unexpected machine outages, allowing production plans to be implemented and improving factory productivity and efficiency.

INA imported bearing accessories selection and loading and unloading precautions

INA imported bearing accessories selection and loading and unloading precautions

Selection of bearing clearance: When purchasing bearings, users generally only inform them of the model and grade, and rarely ask for the clearance of bearings. Business personnel must ask about the conditions of use of INA imported bearings, including INA imported bearings.
