Double Row Cylindrical Roller Bearing/NN3056K/Rolling Bearing Made in China
Here is an introduction to the Double Row Cylindrical Roller Bearing:
1. Structure: The Double Row Cylindrical Roller Bearing consists of two inner rings, two outer rings, and cylindrical rollers positioned between the inner rings. The rollers are cylindrical in shape and arranged in a row along the axis, separated by a cage. This design allows the bearing to withstand significant radial loads and certain axial loads.
2. Load-bearing capacity: Due to the arrangement of two rows of rollers, the Double Row Cylindrical Roller Bearing has a higher load-bearing capacity compared to single row cylindrical roller bearings. They are suitable for applications that require handling larger radial loads and smaller axial loads.
3. High rigidity: The design of the cylindrical rollers and the cage in the Double Row Cylindrical Roller Bearing provides it with high rigidity. This high rigidity helps the bearing maintain stability and reliability under high-speed and heavy-load conditions.
4. Automatic alignment capability: The Double Row Cylindrical Roller Bearing, with its two inner rings and two outer rings, possesses good automatic alignment capability. This means that during installation and operation, the bearing can automatically adjust and accommodate minor deviations in the shaft and housing, ensuring smooth operation.
5. Applications: Double Row Cylindrical Roller Bearings are widely used in applications such as construction machinery, metallurgical equipment, mining equipment, crane machinery, rolling mills, excavators, wind power generation equipment, and other industries that require high load-bearing capacity and rigidity.
In summary, the Double Row Cylindrical Roller Bearing offers high load-bearing capacity, rigidity, and automatic alignment capability. It is well-suited for industrial applications that require handling significant loads and high reliability.
