[tab name='More Information']
The NU type cylindrical roller bearing is a specific type of roller bearing widely used in various mechanical applications. It belongs to the family of cylindrical roller bearings, known for their ability to provide high radial load capacity and moderate axial load capacity.

The NU type designation stands for "non-locating unit," indicating that this bearing design does not have ribs on either the inner or outer ring, allowing for axial movement. This feature enables the NU type bearing to accommodate thermal expansion or contraction of the shaft or housing without causing excessive stress or misalignment.

NU 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 particularly suitable for applications where high radial loads are expected, such as in heavy machinery, gearboxes, electric motors, and automotive applications. The absence of ribs allows for more flexibility in axial movement, making them suitable for applications with thermal variations or shaft misalignment.

NU type cylindrical roller bearings are designed to operate at high speeds with low friction and provide reliable and smooth operation. They are available in various sizes and configurations to accommodate different load and speed requirements.

Overall, the NU type cylindrical roller bearing offers a robust and efficient solution for applications requiring high radial load capacity, moderate axial load capacity, and axial movement flexibility.
