The sealing structure design and lubrication and maintenance technology of deep groove ball bearings guarantee the extension of bearing life

The sealing structure design of deep groove ball bearings is the first line of defense to prevent pollutant intrusion and lubricant leakage, and it plays an important role in extending the service life of bearings.According to the requirements of the use environment and working conditions, deep groove ball bearings can be sealed in a variety of forms, including dust caps, rubber seals and labyrinth seals.The dust cover is usually made of steel plate stamped with a small gap between it and the inner ring, which can block larger particles of dust and foreign objects, and is suitable for cleaner environments.The rubber sealing ring forms a dynamic seal in contact with the inner ring, which has a better sealing effect, can effectively prevent the invasion of fine dust and moisture, and reduce grease leakage. It is suitable for dusty or humid environments.

The lubrication and maintenance technology of deep groove ball bearings is directly related to the operating state and life performance of the bearings.Grease is the most common lubrication method for deep groove ball bearings. Its role is to form an oil film on the rolling contact surface, reduce friction and wear, and at the same time play an auxiliary role in heat dissipation, rust prevention and sealing.The filling amount of grease needs to be properly controlled. Too much will cause the stirring resistance to increase and the temperature rise to be too high; too little will cause insufficient lubrication and accelerate wear.For sealed bearings, quantitative grease has been filled at the factory, and long-term maintenance-free can be achieved under normal operating conditions.For open bearings or heavy-duty and high-speed working conditions, grease needs to be replenished or replaced regularly to maintain lubrication performance.

The lubrication and maintenance cycle and method of deep groove ball bearings should be determined according to specific working conditions.For bearings operating in a clean environment, normal temperature, and light load conditions, the lubrication and maintenance cycle can be appropriately extended; in dusty, high temperature, heavy load, or humid environments, the maintenance cycle needs to be shortened.When supplementing grease, products with the same grade and base oil viscosity as the original grease should be used to avoid adverse reactions caused by mixing different components of grease.The amount of fat added should be moderate, based on the principle of a small amount and multiple times, to avoid excessive fat addition leading to excessive temperature rise.For important equipment, vibration monitoring, temperature monitoring and oil analysis can be used to determine the lubrication status and wear of bearings, and to achieve maintenance as appropriate.Through reasonable sealing design and standardized lubrication and maintenance, the service life of deep groove ball bearings can be significantly extended and the reliability of equipment operation can be improved.
