Bearing characteristics of deep groove ball bearings
Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing, and can bear combined radial and axial loads. When the rotation speed is high and it is not suitable to use thrust ball bearings, it can also be used to bear pure axial load. Compared with other types of bearings with the same specifications and dimensions as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for bearing heavy loads.

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
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.

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.
