Deep groove ball bearing with seals or shields Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea ling prolongs bearing service life Simple, versatile and robust design Low friction and high-speed capability Accommodate radial and axial loads in both directions Require little maintenance |  | ||||||||
Knowledge and introduction of bearings : | |||||||||
The 6921 bearing is a type of deep groove ball bearing that is widely used in various industrial and mechanical applications. Below is a detailed introduction to the 6921 bearing in English: OverviewThe 6921 bearing belongs to the deep groove ball bearing family, which is characterized by its ability to support radial loads as well as moderate axial loads in both directions. This versatility makes it suitable for a wide range of applications. DimensionsThe 6921 bearing has standard dimensions that include:
These dimensions make the 6921 bearing suitable for use in various mechanical systems where these size requirements are met. Load CapacityThe 6921 bearing is designed to support significant loads. Its load capacity, which includes both radial and axial loads, is determined by its design and material properties. Manufacturers often provide specific load ratings for their bearings, which indicate the maximum loads that the bearing can support without failing. Material and ConstructionThe 6921 bearing is typically made of high-quality steel, which provides excellent strength and durability. The rolling elements (balls) and races are precision-manufactured to ensure smooth and efficient operation. The bearing is also sealed to prevent contaminants from entering and damaging the internal components. LubricationProper lubrication is essential for the performance and lifespan of the 6921 bearing. Lubricants such as oil or grease are used to reduce friction and wear between the rolling elements and races. The choice of lubricant depends on the operating conditions, including speed, temperature, and load. ApplicationsThe 6921 bearing is used in a wide range of applications, including:
MaintenanceRegular maintenance and inspection of the 6921 bearing are crucial to ensure its long-term performance and reliability. This includes checking for wear, cracks, and lubrication levels, as well as replacing the bearing if it shows signs of damage or wear. In conclusion, the 6921 bearing is a versatile and reliable deep groove ball bearing that is suitable for a wide range of industrial and mechanical applications. Its standard dimensions, load capacity, material properties, and lubrication requirements make it an excellent choice for many systems. Regular maintenance and inspection are essential to ensure its continued performance and reliability. | |||||||||
