[tab name='More Information']
The N type cylindrical roller bearing is a specific type of roller bearing that is widely used in applications where high radial load capacity is required without axial guidance. It belongs to the family of cylindrical roller bearings, known for their ability to support heavy radial loads and moderate speeds.

The N designation indicates that this bearing does not have any integral flanges or ribs on either the inner or outer ring. As a result, it does not provide any axial guidance for the shaft. This design allows for axial movement of the shaft relative to the housing, making it suitable for applications where thermal expansion or contraction is expected, or where axial positioning is not critical.

N type cylindrical roller bearings consist of an inner ring, an outer ring, cylindrical rollers, and a cage assembly. The cylindrical rollers are arranged in parallel between the inner and outer rings and guided by the cage, which maintains their proper spacing and prevents excessive friction between the rollers.

These bearings are commonly used in applications such as electric motors, pumps, conveyor systems, and general machinery, where the focus is primarily on supporting radial loads. The absence of flanges or ribs allows for more flexibility in axial movement, making them suitable for applications with thermal variations or shaft misalignment.

N type cylindrical roller bearings offer high radial load carrying capacity, excellent rigidity, and smooth operation. They are designed to operate at moderate to high speeds with low friction, providing reliable performance in demanding environments.

In summary, the N type cylindrical roller bearing is designed to provide high radial load capacity without axial guidance. Its simple design allows for axial movement, making it suitable for applications where thermal expansion or axial positioning is not critical. These bearings offer reliable operation and are commonly used in various industrial applications.
