What is the impact of the working environment on the operating efficiency of deep groove ball bearing 63 series

Deep groove ball bearings are key components in mechanical transmission systems, and their operating efficiency is affected by many factors, especially changes in the working environment. Taking the 63 series deep groove ball bearings as an example, factors such as temperature, humidity, pollutants and vibration in the working environment may directly or indirectly affect the lubrication state, material properties, vibration level and overall working stability of the bearings. These changes not only affect friction loss and heat generation, but may also significantly shorten the service life and increase maintenance costs.

The impact of temperature changes on deep groove ball bearings is particularly obvious. High temperature environments will cause the viscosity of lubricating grease to decrease, the lubricating film to become thin or even fail, resulting in direct metal contact between the rolling elements and the raceways. At this time, the friction coefficient increases, energy loss increases, and heat accumulation is accompanied, forming a vicious cycle, and ultimately shortening the service life of the bearing. Conversely, low temperature environments will make the lubricating grease viscous and the lubricating film thicken, hindering the movement of the rolling elements. Although the friction coefficient may be reduced, the resistance at startup increases, resulting in increased energy consumption, and intensified shock and vibration during startup, affecting the smooth operation of the bearing.

The presence of humidity and water vapor is also an important factor affecting the efficiency of deep groove ball bearings. High humidity environment easily leads to corrosion of metal parts. Corrosion not only destroys the metal surface, forming corrosion spots and cracks, but also may contaminate lubricating grease, form oxide layer or corrosion products, reduce lubrication effect, increase friction and wear. The intrusion of water will lead to the decline of lubricant performance, the lubricating film becomes uneven, which in turn affects the friction resistance and heat accumulation, and reduces the stability and reliability of the bearing. Especially at the seaside or in humid areas, the salt and corrosive gases in the environment will accelerate metal corrosion, shorten the service life of the bearing, and increase the maintenance frequency and cost.

In addition, the intrusion of dust, impurities and pollutants is also an important factor affecting the performance of deep groove ball bearings. In a working environment with a lot of dust or serious pollution, dust particles can easily enter the bearing, adhere to the rolling element and raceway surface, form abrasive particles, cause local wear and scratches, increase the friction coefficient, and then lead to increased energy loss. The accumulation of pollutants may also cause the deterioration of lubricating grease, accelerate the aging of lubricants, reduce their lubrication performance, and make the bearing produce greater vibration and noise when running at high speed, and even cause local failure in severe cases. In industrial environments with high dust concentrations, the quality of sealing performance is directly related to the operating efficiency and life of the bearing. Poor sealing will allow pollutants to penetrate, affect the lubrication state, and increase the difficulty of maintenance.

Vibration and impact loads also have an adverse effect on the operating efficiency of deep groove ball bearings in complex or harsh working environments. When mechanical equipment works in a vibrating environment, the vibration force on the bearing may cause eccentric movement of the rolling element and local deformation of the raceway, increase friction resistance, and lead to increased energy loss. Impact loads will cause local stress concentration in the bearing, accelerate the fatigue failure process, produce cracks and peeling, and further shorten the service life of the bearing.
